F I XE D S YS TE M DATA S H E E T

The LPT is an economical, single sensor, analog transmitter available
with either a Carbon monoxide (CO) or Nitrogen dioxide (NO2) sensor
which are ideal for vehicle exhaust type applications such as parkades.
It features 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, all in a RoHS compliant package. 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.
With the optional splash guard installed, the enclosure is IP54 rated ideal for use in water spray or wash down applications.

Note: Drawings above are shown with an optional splash guard. Without splash guard,
thickness of unit is 2.1” (53.34 mm).

WIRING

Automated calibration and other maintenance procedures are simple and
easily performed in the field, and our proprietary Calibration Extending
Firmware (CEF) takes into account the aging of the sensors so that less
frequent calibrations are acceptable in non-critical applications.
