Digital Process Indicators
A range of programmable, flexible and easy to use process indicators is available, for monitoring conditions of a wide range of inputs. Outputs can be analogue, RS232 or BCD signal output, as well as LED indicators as standard.Request a Quote Supplied by Lee-Dickens Ltd -
Dual Level Trip Amplifier - DC Powered - DIN Rail Mounting
Dual Level Trip Amplifier from a single process signal input. The trip action can be arranged so that the Alarm condition can be above (High Trip) or below (Low Trip) each of the set points, and that the relays can be either normally energised to de-energise in the Alarm condition (Fail-Safe), or normally de-energised to energise in the Alarm condition (Non Fail-Safe).Request a Quote Supplied by Lee-Dickens Ltd -
Dual Level Trip Amplifiers
Dual level trip amplifiers operate from a single process input, with a dual trip action which can be arranged so that the alarm conditions are triggered either above or below each of the defined set pointsRequest a Quote Supplied by Lee-Dickens Ltd -
Dual Output Isolating Signal Converter - DC Powered - DIN Rail Mounting
Isolating signal converter which will convert a range of process signals into two independently isolated current or voltage outputs. The BM320 is ideally suited to providing signals for both local indication/control and remote monitoring and control from the one input signal. The BM320 still maintains three port isolation with the input and both output circuits powered from separate secondaries of the DC/DC converter.Request a Quote Supplied by Lee-Dickens Ltd -
Flow Meter Alarm
We offer a number of universally powered Alarm Units/Trip Amplifiers suitable for use with a range of different VA Flowmeters. The units can be configured for use as a Low or a High Flow Alarm, as required.Request a Quote Supplied by Lee-Dickens Ltd -
Frequency to Current/Voltage Converter - Mains Powered - DIN Rail Mounting
Isolating signal converter which will convert from a frequency range to an analogue output. The MicroFREQ F-A is a microprocessor based signal converter and can therefore be programmed by the user to specify the input and output frequency type and ranges. Both the input and output stages of the instruments are powered from separate secondaries of the transformer thus maintaining 3 port isolation. The MicroFREQ F-A has the programming function resident in memory.Request a Quote Supplied by Lee-Dickens Ltd -
Frequency to Current/Voltage Converter - Mains Powered - DIN Rail Mounting
This replaces the DIN200. Conversion of an input frequency to a linearly proportional, isolated output current or voltage. The BD200 can be used to monitor the speed of rotating machinery and can be followed by a BD100/BD120 trip amplifier to give alarm, control or shutdown facilities at preset levels of speed. It is ideally suited for use with turbine flow meters to give an analogue measurement of flow rate, and with proximity detectors for non-contact speed measurement. The BD200 incorporates both a sensitivity adjustment and a reference voltage to allow a variety of sensor types to be used.Request a Quote Supplied by Lee-Dickens Ltd -
Hand Held & OEM Probes
Lee-Dickens can offer several formats of Hand Held and OEM probes to suit all sorts of applications. The OP5 is an attractively priced Relative Humidity probe for the OEM market. The physical format for the OP5 outlined in the details below is that of a hand held probe. If duct or wall mounting versions are required, we can mount the electronics in an enclosure to suit your own requirement. Alternatively we can supply duct or wall mounting adapters for the hand held format. Please contact our internal sales department to discuss your specific application.Request a Quote Supplied by Lee-Dickens Ltd -
Instrument Power Supply - Mains Powered - DIN Rail Mounting
General purpose 24 Volt DC instrument power supply unit. The DIN700 will isolate and convert 110 Volts AC or 240 Volts AC 50/60Hz to 24 Volts DC for use with loop powered transmitters or 24 Volt DC powered instruments. For example the DIN700 can be used to supply up to six units from the AlphaMINI range of Signal Conditioning Equipment and Trip Amplifiers or any of the Flow, Level, Temperature or Relative Humidity transmitters located elsewhere in this catalogue.Request a Quote Supplied by Lee-Dickens Ltd -
Intrinsically Safe Relative Humidity Transmitter - Duct Mounting
The HP140IS is a Duct mounting Intrinsically Safe Relative Humidity transmitter. The HP140IS has been approved by Baseefa (2001) Ltd for use in Zone 20 conditions and is certified to II 1 GD EEx ia IIC T4 -20°C =Ta =+70°C GAS & DUST certificate number Baseefa03ATEX0101X/1. The probe operates as a two wire transmitter and produces a 4 to 20mA output proportional to 0 to 100% Relative Humidity. Interface to the safe area must be via approved barriers. Baseefa (2001) Ltd have also approved the system drawings in the pdf file using MTL7728-ve or MTL7788R+ve barriers. The system certificate number is Baseefa03Y0103.Request a Quote Supplied by Lee-Dickens Ltd
