Critical Environmental Technologies announce the release of the new LPT Low Power Transmitter.

LPT is an economical, single sensor, “Low Power Transmitter”. Sensors available include carbon monoxide (CO) and nitrogen dioxide (NO2) which are ideal for vehicle exhaust type applications such as carparks.

LPT transmitters feature a two-wire loop, three-wire VDC or four-wire VAC power making installation simple. LPT transmitters also features a 4 - 20 mA linear output signal, automatic thermal resetting fuse, RoHS compliant circuit boards, temperature compensation, and visual LED indication for power and fault conditions. The sensor is enclosed in a standard water / dust tight (drip proof) ABS / polycarbonate enclosure that is equivalent to IP62 (NEMA 12) rating.

New sensor CEF (Calibration Extending Firmware) is included that takes into account the aging of the sensors so that less frequent calibrations are required for non-critical applications.

Automated calibration and other maintenance procedures are simple and easily performed in the field.
