We have been developing and manufacturing a wide range of measurement instruments since 1916, always with an emphasis on quality and durability. As our products remain in use throughout the world we continue to support our customers with spares, repairs and replacements.
In 2001 we joined with Rheintacho GmbH to create one of the largest rotational speed measurement manufacturers in the world. Rheintacho bring 100 years of additional expertise, especially in the field of non-contact sensors and stroboscopes.
As a consequence, our expanded range now covers a wide selection of products for the measurement, indication and control of rotational speed together with a range of stroboscopes for quality control and maintenance. 
Our handheld portable range of tachometers and stroboscopes provides the user with the ability to measure speed and distance as well as carrying out maintenance checks by creating a ‘frozen’ image using a strobe. With equipment for use in a range of environments and applications there is a solution for every need. 
Where a fixed solution is required we offer stroboscopes with a range of light sources, widths and trigger configurations to suit individual demands.
Our rotational speed instruments range from mechanical indicators which are directly connected to moving components, to non-contact sensors which generate a signal from the component and transmit this to electronic devices for control and indication. With this range we have the capability to supply effective solutions from stock, or to engineer existing products to meet specific requirements, either as a ‘one-off’ or for a serial production.
Our technical strength is key to remaining at the forefront of our industry, and we work closely with our clients during the product development process to ensure that when we design and develop a product for them it meets the specification and adds value to the finished product. Quality, accuracy and durability are fundamental to our success.

  1. Extremely Compact – Extremely Robust – Extremely Versatile RHEINTACHO Speed Sensors of the FE Series
    3 March 2020

    Peter Cisar, Head of Development at RHEINTACHO, is enthusiastic about the FE series: “With the FE series, we offer a speed sensor family that offers a variety of different signal outputs in a compact design – in addition to meeting the highest protection requirements with IP67 and IP6K9K."

    There are two different immersion depths,18.4mm and 32mm, available as standard. This offers the possibility to select the optimal sensor for the respective installation conditions.

    Another technical detail to increase flexibility is the deliberate avoidance of a connector integrated directly on the sensor body. This reduces the risk that the connector is located at a structurally unfavorable point in the overall system. Another advantage of the cable outlet is the relocation of the connector to a more suitable position, especially with regard to environmental conditions such as moisture, dirt/dust as well as vibration. In particular, vibration should not be underestimated. The space requirement of common connector systems is also disadvantageous in relation to this very compact sensor - an important aspect in restricted installation positions. For optimal protection against the ingress of moisture, connectors molded directly onto the cable or molded on the back are used.

    Today, RHEINTACHO offers the FE series with these different output signals: 1-channel (for speed detection), 2-channel (for detection of speed and direction of rotation) and a pulse-width modulated current signal (also speed and direction, as well as diagnostic options).

    The advantages of the RHEINTACHO FE concept are obvious: A sensor series which is specified and approved for an application. The mechanical interfaces are identical, regardless of which signal you or your users choose. With the RHEINTACHO FE series, you choose the right speed sensor precisely for the requirements of the application.

    Application-Report - Electro race car

    Application:

    LA eRacing e.V. requires a very robust yet small rotational speed sensor for an electro race car. This sensor has to determine the rotational speed on small gears with a high resolution.

    Task:

    In order to determine the speed of the race car, the rotational speed of the wheels should be measured by using a sensor. This would also enable distance and reach to be calculated.

    A further point is the so called „Torque Vectoring“. If the exact rotational speed of the wheels is known, the torque of the two motors can be specifically adjusted and hence the drive torque of the wheels can be corrected. This means that when a car is understeered in a curve, the outside wheel can be driven more strongly to get back to a straight track. In addition, the rotational speed is necessary for torque control to prevent the rear wheels from slipping while accelerating.

    Solution/ Result:

    The desicion was made to use the 1-channel hall difference sensor SDN11.FE00.E1R. This sensor is perfect for the requirements considering its small installation size and its resolution. In addition, it also is IP67 certified and therefore well-suited for the car.

    LA eRacing:

    LA eRacing is an independent club of the university of Landshut, Germany. The presently active 100 members are composed of interdisciplinary students of the Landshut University.
    The involved faculties include business administration, electrotechnology and industrial engineering, information technology, interdisciplinary studies, mechanical engineering and social work.
    The objective is an own development of an electro race car which will be used to participate in Formula Student racing events. This enables the members to use both their technical and business knowledge in practice. In addition, the cooperation in the team strengthens the teamworking abilities of each member.

    RHEINTACHO is a flexible, highly efficient partner- wherever speed must be measured, monitored or indicated. Innovation, the most modern production techniques and equipment, meticulous quality control along with a first-class workforce are the corner stones of our company. For the past 114 years, Rheintacho has used his extensive knowledge and experience to developed sensors, systems and customized solution to meet the customer’s requirements.

  4. The RHEINTACHO “Black box” Or: Measuring infinite light
    15 May 2018

    In the final assembly of stroboscopes at RHEINTACHO, there is probably a measuring unit which is unique worldwide. With this system, the light intensity of RHEINTACHO stroboscopes is measured and shown graphically.

     

    From the outside, it looks like an inconspicuous, built-to-purpose square "box”. However, it is full of complicated and intelligent technology. We are dealing with the measurement of light intensity of extremely short flashes of light. These light flashes can be as short as 5µs. In this short time, the special xenon light units reach a brightness of mega-lux level.

     

    With such a concentration of light, conventional methods of brightness measurement would not provide any usable results.

    And in connection with the large stationary stroboscopes, this becomes a real problem – a good reason for the stroboscope specialists in the RHEINTACHO development department to find a solution for this. And they have been very successful.

    Every RHEINTACHO stroboscope is checked and released on this test rig and an individual test report is created. The determined data is stored in the test software. For some of the portable stroboscopes, such a test certificate is supplied with the device.

     

    One important task of the “black box” has already been realized: using this system, the components responsible for light efficiency and light distribution can be designed and selected significantly more quickly, purposefully, based on objective measuring data.

    This is how, for example, the reflectors for the xenon stroboscopes were optimized. For LED stroboscopes, the measuring unit provides important data for the selection and arrangement of the LED’s and the design of the lenses.

    After a very good year in 2016, both RHEINTACHO Messtechnik in Freiburg, Germany and RHEINTACHO UK in Leeds, increased their sales by more than 25 % in 2017.

    Several large new contracts and many new developments in sensors enabled to tackle the increasingly difficult international sensor market with great success and also provide a very positive overlook for the future. Significant new developments include two sensor series which integrate more than the traditional rotational speed detection. The M8 series now includes a temperature sensor and the ABZ series can not only measure rotational speed but also the direction of rotation as well as position! The additional features offer not only technical but also cost advantages to users. Further developments in this area are nearing the launch of sales. Both innovations will be present at the Hanover fair CeMAT.

    A spectacular feature will be present in a new version of the hand stroboscope RT STROBE pocketLED in Hanover: The auto-sync function using a laser beam and a clever signal-receiving.

    The subsidiary RT UK in England with the bespoke craftsmanship present in Leeds, Yorkshire continues to be a specialist in the production of mechanical and electrical instruments and tachometers. Together with over 110 years of experience available from the German parent company and its own combination of over 200 years of experience from Foundrometers Instrumentation and Hardings of Leeds, history is accompanying the RHEINTACHO group into the future.

    RHEINTACHO UK has specialized in the development of ATEX products. These are often used in areas where there is sometimes a risk of explosive atmospheres due to either dust particles or gases. As the newly appointed ATEX competence center within the RHEINTACHO Group, they are currently developing ATEX versions of some well-proven and established products.

    IP67 IP

    Task:

    The speed and rotation of direction of hydrostatic drives are

    to be measured and passed on to the control system. The

    environmental conditions place extreme demands on the

    reliability and sturdiness of the sensors.

    These drives can be used for snowplows, street cleaning

    vehicles, agricultural machines and any sort of construction

    machines. But they can also be used in drill heads of tunnel

    boring machines or in special vehicles.

    Depending on the version, the two-channel differential halleffect

    sensors of the FA series either transmit two frequency

    signals, which are phase shifted by 90° or one frequency

    signal, and one rotational direction signal (0 / 24 V).

    These sensors can be used at pressures of up to 10 bar and

    at temperatures of between –40 °C and +125 °C. They meet

    the toughest requirements in terms of thermal shock resistance,

    electromagnetic compatibility, vibration resistance,

    shock resistance and resistance against known oil types,

    diesel, salt fog and high-pressure cleaners.

    The sensors are protected by special individual wire seals,

    among others from fluids entering them through cables

    (IP69K protection class).

    Another solution could also be the FE Push-Pull series. These

    sensors not only impress with their small size but also with

    their high protection class IP6K9K.

     

     

    Furthermore the output signal push-pull offers more flexibility

    regarding electronic connection. This sensors comes

    in standard with cable length 1500 mm and an overmolded

    DEUTSCH connector DT04-4P.

    The sensors are used in hydrostatic drives exclusively by

  8. Hazardex
    21 March 2017

    When RHEINTACHO decided to enter the ATEX product market 3 years ago, with its mechanical hand-tachometer htm, no one then anticipated winning an award for technical innovation of the year only 3 years later.
        The global market lacked a stroboscope which was ATEX certified and the only one previously available was discontinued in 2016. RHEINTACHO then decided to act and did two things. First of all, we created a task force based in Leeds to analyze the market for ATEX strobes taking potential applications and volumes into consideration. We then decided to modify some existing stroboscopes to enable them to get ATEX certification. One of them, our RT STROBE pocket LED, is now in the process of being certified. We are also examining further strobes and some sensors and digital hand-tachometers for ATEX certification as well.
    However, there being a void in ATEX strobes throughout the world, we looked for a quick solution to this problem. Together with a partner for enclosures, Extronics, we enclosed a RHEINTACHO LED stationary stroboscope. This ATEX system is now available in 2 sizes using the 3000 and 5000 versions of the LED stroboscope.
    This innovative technical innovation provides the market with an immediate and very robust solution for Zone 2 applications. The award as runner-up in this category was presented to Paul Hargraves, Managing Director and William Buhler, Sales, Marketing and Business Development Manager of RHEINTACHO UK, which is the ATEX competence center of the RHEINTACHO Group.

  9. Digital hand-tachometers and ATEX certified devices from RHEINTACHO
    15 February 2017

     

    The reliable and simple recording and monitoring of speed, rotational speed and run length of different materials is part of everyday working life in many companies.

    Therefore, these working steps should be quick and uncomplicated to carry out.

     

    RHEINTACHO Messtechnik GmbH offers the ideal measuring instrument for doing this: the digital hand-tachometer rotaro. Thanks to different measuring attachments, the handy device can be used for many various applications.

    The special adapter for fibre measurement, rotaro T, and the special set for elevator and cable measurement, rotaro Te, have been realized due to individual customer requests.

    RHEINTACHO, well-known for its flexible and customer-oriented corporate philosophy, reacted promptly to them and developed special adapters for the specific demands of the textiles and elevator industries.

     

    Another special adapter for measuring welding wire speed, rotaro Tw, can be applied to optical and mechanical measurement of welding wire feed speed and is a reliable tool for quality control of welding-based production.

     

    The basic device rotaro consists of wheels, measuring funnel and tip for mechanical measurements as well as reflective tapes for optical, and therefore non-contacting measurement.

    The digital hand tachometers are just as useful when setting up plants and machinery as during service jobs, monitoring manufacturing processes or in development laboratories. Example applications include measuring the rotational speeds of engines, pumps and turbines, as well as of mixers, centrifuges and conveyors; it can also measure the velocities and lengths of all kinds of sheets and belts.

    In addition to our versatile rotaro product line, RHEINTACHO is becoming an important player in the world of ATEX applications in maintenance and processing. RHEINTACHO’s English subsidiary, RHEINTACHO UK, is now the group’s Competence Center for ATEX applications and products. The first product, a handheld mechanical tachometer (HTM), was introduced with zone 2 certification in 2015 and this has since been upgraded to zone 1 to enable applications in mines. In 2016, two stationary solutions for RHEINTACHO stroboscopes in special zone 2 ATEX enclosures were introduced for applications in the printing and packaging industries. At present, further products ranging from stroboscopes to sensors are being developed and investigated to further complement RHEINTACHO’s portfolio of ATEX products.

     

     

    RHEINTACHO and the world of ATEX devices and applications – an ever-increasing reciprocal relationship for our customers.

  10. Application report - Service / Maintenance of electric motors with digital hand-tachometers redpoint / rotaro
    22 November 2016

    Task:

    During the production of electric motors, the speed is to record at a certain current consumption during the final test.

    This requires a speed-measuring device, which quickly and precisely measures and saves the speed.

    Here, a calibrated measuring system is desired, too.

    Solution:

    With the digital hand-tachometer rotaro, a mechanical adapter and probe tip are used to measure the rotational speed of the motor and store it in the memory.

    The value is retrieved later and recorded in the test log together with the current consumption.

    The digital hand-tachometer redpoint can also be used to measure the speed visually without contact, using a reflective strip.

  11. The RHEINTACHO Group, has now increased its efforts to provide the ATEX world with more devices which can be used in hazardous areas.
    12 October 2016

    After introducing the handheld mechanical tachometer for Zone 2 applications in August 2014, this product was upgraded to enable it to be used in Zone 1 hazardous areas such as mines in November 2015. The success of this product as well as its ease of use, has led many companies to implement it in maintenance processes on site and in repair shops as well.

    The newest and second addition to RHEINTACHO’S ATEX family is the introduction of two types of enclosure which are both Zone 1 approved. Within these enclosures, either the Rheintacho LED Stationary Strobe 3000 or 5000 are fitted and wired within them. The 5000 enclosure is a bit larger than the 3000 enclosure. Both are then wired to a DIN rail inside the enclosure. The cable leaving the enclosure through an ATEX gland, is routed to a safe area, (meaning outside the hazardous zone) and is connected via a 5-pin plug to the RHEINTACHO strobe control which provides and receives signals as well as provides power to the strobe.

    This enclosure can easily be mounted in printing areas or elsewhere to facilitate the inspection of high-speed surfaces and as a highly efficient light source for use in industrial image processing technology. Despite the characteristics of the enclosure no cooling is required and no soiling or other contamination occurs with the strobe being inside.

    There is very little to no effect on the brightness or illuminated area through the window in the enclosure due to its position close to the window.

    23 September 2016

    The reliable and simple recording and monitoring of speed, rotational speed and run length of different materials is part of everyday working life in many companies.

    Therefore, these working steps should be quick and uncomplicated to carry out.

  13. IP69K: FQ rotational speed sensors from RHEINTACHO
    23 September 2016

    The intelligent continuation of a success story

    With its high IP69K protection class, RHEINTACHO is set to introduce a complete new series of plastic sensors for detecting rotational speed and direction from the second quarter of 2016.

    Thanks to different sensor lengths, cable outlet directions and connector options, this product line offers users a high degree of flexibility, enabling adaptation to entirely individual requirements. And even if none of the available models is suitable, RHEINTACHO will be pleased to draw on its recognised expertise in customised solutions to develop the right solution for you.

    Why IP69K? RHEINTACHO Sales Manager Wolfgang Sexauer: "There are two main reasons why we were motivated to develop this new series. Firstly, we see a tendency to specify higher IP classes in many applications for safety reasons, than was the case a few years ago. Secondly, the IP69K protection class enables technical potentials to be realised even more efficiently today. This applies to both available materials and, of course, to intelligent constructions."

    The FQ product line is consequently a further development of the current FK product line, which fulfils protection class IP65. In recent years the FK sensors have developed into a genuine success model. Numerous electromotor applications would be inconceivable without these rotational speed sensors. The basic geometrical data for the RHEINTACHO FK has meanwhile been adopted by significantly larger competitors too.

    The electronic design of the FQ product line is successively complemented with different variants in order to fulfil different requirements. In detail: Frequency range, detection distance, EMC and temperature stability. According to the current development plan, all versions will be designed as a two-channel sensor, enabling the detection of rotational speed and direction of rotation.

    RHEINTACHO wholeheartedly welcomes higher specifications from users in regard to its sensors. "Our experience has shown that specifying too low an IP class and putting the onus on users via operating or maintenance instructions, is not practical. This simply doesn’t work", continues Wolfgang Sexauer. "When a machine is to be cleaned with a steam jet for practical reasons, it is difficult to convince the operators otherwise – regardless of what is found in the operating manuals. Subsequent problems "in the field" are then inevitable. Whether in consideration of all actual costs a more cost-effective, lower-specified component is then the means of choice is at least doubtful. And just for this reason we are expanding the proven FK product line to include the FQ series with its higher protection class. We always strive to offer the best technical and economic solution, tailored to the specific application."

  14. RHEINTACHO FE Rotational speed sensor ¿ the one that does it all
    23 September 2016

    The three musketeers of the sensor world: installation-compatible 1-channel,

    2-channel, PWM

    The RHEINTACHO FE rotational speed sensor provides you with today’s most frequently used signal forms: 1-channel, 2-channel and PWM signal output. Three different electronic versions, each in installation-compatible, highly compact housings.

    It doesn’t matter whether you’re a manufacturer who equips their hydraulic units with rotational speed measurement devices or whether you’re a user who buys such units from highly regarded suppliers. You know the question. From the user’s perspective it goes: “Does the standard integrated solution for measuring rotational speed fit?” All too frequently, you have to answer: “No”.

    Now let us step into the shoes of the hydraulics supplier and ask the same question: “Does your standard-use rotational speed measurement device fit your customer’s demands precisely?” Probably, the answer here is all too often also: “No”.

    As competent partners, you do of course find a solution. No doubt a well-functioning custom solution. But unfortunately, it comes with all the mixed blessings that custom solutions imply. We all know the indisputable advantages of the typically German enthusiasm for custom solutions that are usually nice and smart. So allow us to mention just a couple of the disadvantages: project-related, unplanned development expenditure; no amortisation with larger numbers of items; additional testing and qualification expenditure; additional documentation expenditure; defect potential when upgrading the system; defect potential when servicing ‘in the field’.

    At this point, the engineers at RHEINTACHO would like to cry out: “It doesn’t have to be like this!”

    For decades, RHEINTACHO has been a successful supplier of rotational speed counting solutions for hydraulic drive units and has participated in and helped to shape many stages of development in this market. During this time, the scenario sketched out above has also come to pass at RHEINTACHO all too often. Therefore, one of the main targets in the development of the new sensor range right from the first analyses and feasibility studies was to take into consideration the various electronic variants typically found on the market and to allow these to influence the product development process at an early stage.

    And it turns out it paid off. The RHEINTACHO FE range offers three (3) different electronic versions (1-channel, 2-channel, PWM), two (2) different immersion depths (18.4 mm and 32 mm) and a variety of different cable lengths and types of plugs (on the cable).

    All sensors in this range are built to protection classes IP6K9K and IP67.

    The 1-channel version is the ideal choice if the needs are limited to the measurement of rotational speed. Carefully selected components guarantee highly tolerant contact behaviour with respect to all types of target geometries and air gaps. The output signal here is a square wave, the amplitude of which is independent of the rotational speed. In this way, stable signals are achieved even with slow rotational speeds.

    With its two phase-shifted square wave signals, the 2-channel solution offers the same advantages as mentioned above. However, with its two offset signals, you have the additional possibility of identifying the direction of rotation.

    In contrast to the two variants described above (voltage signal), the 2-channel construction with pulse-width modulated signal (PWM) works using a current signal, with information regarding the rotational direction transmitted via the varying length of the pulses. In this way, this sensor also produces a signal with constant amplitude, independent of the rotational speed. This sensor boasts not only the ability to identify the rotational direction; it can also carry out other diagnostic functions such as the identification of idle status, a critical air gap and critical installation position.

    The advantages of the RHEINTACHO FE concept are easy to see: a sensor range for your hydraulic unit is specified and released. The mechanical interfaces are identical, regardless of which signal you or your users decide on. You choose the appropriate rotational speed sensor based precisely on the application’s specific requirements.

    Save your time and expertise regarding custom solutions for the situations where there really is no standard solution available!

  15. A world¿s first: Portable stroboscope RT STROBE super qbLED with auto-sync laser function
    23 September 2016

    The portable LED stroboscope RT STROBE super qbLED is the perfect supplement to the existing product line.

    This hand-held stroboscope, which is exceptionally bright thanks to its 118 high-power LEDs, has an outstanding technical highlight, for which RHEINTACHO has applied for a patent. This is the auto-sync laser function. By means of a far-reaching transmission/reception system based on lasers, the flash rate of the stroboscope is synchronised automatically. The system operates to a distance of up to 3 metres, depending on ambient conditions.

    How exactly does this auto-sync laser function work?

    A laser beam sent from the stroboscope is reflected by a reflective tape back to the recipient cell on the front side of the stroboscope. As a result, the control of the stroboscope calculates the rotation rate of the object, feeds in the flash frequency of the stroboscope and outputs it again as a precisely measured value. Through this integrated optical tachometer/stroboscope, this value is absolutely precise and reliable in terms of process. Fluctuating rotational speeds are not a problem. Through the instantaneous control of the flash rate, the user always has the benefit of redundant detection.

    This innovative and patent-pending function is a real highlight at both trade fairs as well as demonstrations: once a speed disc moving at high speed is instantaneously "frozen" with the auto-sync laser function, the presenter is sure to receive a great deal of attention. No tedious, manual adjustment, no installation of any trigger sensors required, and the measured value is instantly displayed.

    The uniqueness of the auto-sync laser function is based on the integration of the laser unit in the stroboscope. The practical implementation of this integration is not trivial, since, in addition to the reflection of the laser, the receiving unit is also achieved by the reflection of the flash of the stroboscope. This extremely bright flash reflection cannot affect a clean and reliable detection of the laser reflection in any way.

    For applications in which the reflex tape cannot be attached directly to the object under observation, an observation function (auto-save) has also been added. Thereby, similar to the focus lock on a photo camera, the speed at a position of the system which rotates with a similar to equal speed can be taken down, and this frequency can then be used for further observation on the position of the system which is actually to be tested.

    More intelligent and useful control functions are easily forgotten in comparison, but they are absolutely worth mentioning. As a result, all RHEINTACHO STROBE qbLED stroboscopes include the option to save the setting parameters on the "memory function" for various applications and to then load them again for later inspection tasks.

    Since these still non-exhaustive lists of functions for various applications are not necessary, the RHEINTACHO employs a 2-stage operating concept. Users can choose between a standard and a professional mode. This allows users to choose between a simple or a complex operation tailored to their specific use of the device. The range of setting options in the professional mode leave the user with nothing to be desired: brightness which is absolute (µs) or relative (degrees), trigger divider, trigger multiplier, phase shift/deceleration which is absolute (ms) or relative (degrees), slow-motion automatic, and trigger edge are selectable.

    A signal amplifier is available as a new optional accessory for all qbLED stroboscopes. This enables vibration test rigs, for example, to be connected to the stroboscope. The stroboscope will then flash automatically with the vibration frequency. As a result, the vibrations of the objects located on the test bench are visible and interpretable to the human eye. With the aforementioned features, the stroboscope can also be parameterised continuously.

    The RT STROBE super qbLED stroboscope, which weighs just over 1 kg, is delivered in a functional and robust case. Handle, calibration certificate, battery charger with plugs, trigger plugs and reflex tapes are also included. Thanks to the integrated lithium-ion batteries, the stroboscope can be operated for up to 7 hours without a break.

    RT STROBE super qbLED is a very good example of how long-proven devices can offer solutions for current and future application tasks through forward-thinking development and the use of the latest technologies.
