Rheintacho UK Ltd

We have been developing and manufacturing a wide range of measurement instruments since 1920, always with an emphasis on quality, durability and service. As our products remain in use throughout the world we continue to support our customers with spares, repairs and replacements and reengineered products.
In 2001 we joined with Rheintacho GmbH to create one of the largest rotational speed measurement manufacturers in the world. Rheintacho brings over 100 years of additional expertise, especially in the field of non-contact rotational speed 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.
We believe that we can provide a cost-effective solution for your needs, and if there is not currently a standard product, please talk to us and see what we can do for you.

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.
