mV3630-W
4-20mA Redox Transmitter
The mV3630-W Redox transmitter is supplied in an optional surface mounting weatherproof enclosure for mounting close to the Redox electrode system. Alternatively, we can supply the mV3630 in a Din Rail Enclosure for mounting within a control panel or system.
The 4-20mA transmitter is designed to connect to a Redox Electrode and then send an industry standard isolated 4-20 mA signal up to 1000 metres away. The mV3630-W Redox transmitter operates from a 24 Volt DC (VDC) supply and the same two wires used to power the transmitter also carry the 4-20mA current signal.
By using only two wires this loop powered device is simple to install and configure to work with a PLC or Digital Chart Recorder.
The mV3630 4-20mA Redox transmitter has a 2 point calibration and a very easy calibration procedure. By calibrating the Zero value and the Span value using a Redox calibration solution, the transmitted 4-20mA signal then precisely follows the corresponding redox measurement.
The 4-20mA Redox transmitter can be powered by the receiving Controller, Recorder, PLC or AWE Instruments model BC7635 digital indicator controller. Where the Redox transmitter doesn't include any control or alarm relays. By using a BC7635 Digital Indicator / Controller, we can have a secondary display complete with built in stabilised power supply and High - Low alarms.
The amount of wiring to connect the transmitter and receiver is minimised and the majority of receiving instruments including AWE Instruments Model BC7635 are initially designed to receive the signal and power the external instrument.
The mV3630 Redox Transmitter is a physically small device and allows precision transmission of an isolated 4-20mA signal corresponding to the Redox value. The device is straightforward to install, easy to use, simple to calibrate and designed to operate in the field for extended periods of time requiring minimal human involvement.
