CET LPT-A Analogue Transmitter

CET LPT-A Analogue Transmitter

The CET LPT-A Analogue Transmitter is an economical, single sensor, analogue transmitter available with a wide range of gas sensors and sensor types including electrochemical, solid state, and catalytic.

All models in the LPT series of transmitters come standard with a water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door. An optional splash guard is also available for water spray or wash down applications. With the splash guard installed, the enclosure is IP54 rated.

Automated calibration and other maintenance procedures are simple, and easily performed in the field. For parking garage applications the Calibration Extending Firmware (CEF) takes into account the ageing of the sensors so that less frequent calibrations are required.
