CETCI to Introduce the LPT Series of Gas Detection Transmitters at AHR Expo 2013

Written by:

Critical Environment Technologies Canada Inc. (CETCI) plans to introduce a series of LPT at the International Air Conditioning, Heating, and Refrigeration (AHR) Expo in Dallas, Texas from January 28 - 30, 2013 at booth 850.

The LPT series will be housed in water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secure door and internally coated EMI paint to eliminate potential EMI and radio frequency interference (RFI) all in a RoHS compliant package. All models will also include the calibration extending firmware (CEF) that takes into account the aging of the sensors in less critical applications.

The original LPT single sensor, analog transmitter was successfully launched in June 2012 with only carbon monoxide (CO) or nitrogen dioxide (NO2) sensor options. This was an economical solution for the commercial HVAC market, specifically for vehicle exhaust type applications. It featured a two-wire loop power, three-wire VDC or four-wire VAC power, 4 - 20 mA linear output signal, automatic thermal resetting fuse, temperature compensation, and visual LED indication for power and fault conditions.

The LPT-A single sensor, analog transmitter comes with a wide range of sensors and sensor types including electrochemical, semi-conductor, and pellister. It features three-wire VDC or four-wire VAC power,  jumper selectable 4 - 20 mA or 0 - 10 VDC analog output, standard dry contact relay (2 amps @ 30 V SPDT), automatic thermal resetting fuse, temperature compensation, visual LED indication for power, alarm, and fault conditions, audible alarm, and optional LCD digital display.

The LPT-D single sensor, digital BACnet® transmitter comes with a wide range of sensors and sensor types including electrochemical, semi-conductor, or pellister. It features four-wire network connectivity (power and MS / TP Bacnet® communications), automatic thermal resetting fuse, temperature compensation, LED indicator for power, alarm, and fault conditions, and optional LCD digital display.

The LPT-E dual sensor, digital BACnet® transmitter comes with a standard electrochemical CO sensor and choices of NO2, nitric oxide (NO), oxygen (O2), or sulphur dioxide (SO2). It features four-wire network connectivity (power and MS / TP Bacnet® communications), automatic thermal resetting fuse, temperature compensation, LED indicator for power, alarm, and fault conditions, and standard LCD display.
