LPT Low Power Transmitter
Single channel, analog gas detector for enclosed parking facilities, recreational facilities, oxygen depletion applications.
- Single channel
- Linear 4 - 20 mA output signal
- 2-wire loop, 3-wire VDC or 4-wire VAC power
- Standard water / dust tight, corrosion resistant enclosure (drip proof)
Description
The LPT is an economical, single sensor, analog transmitter for monitoring toxic gases non-hazardous, non-explosion proof rated commercial and light industrial applications. This basic transmitter is designed to be part of a fixed system with a Controller for applications such as car parks, vehicle repair, aquatic centers, ice rinks and oxygen depletion applications. It features a two-wire loop power, three-wire VDC or four-wire VAC power, 4 - 20 mA linear output signal, thermal resetting fuses, temperature compensation, and visual LED indication for power and fault conditions, all in a RoHS compliant package. Comes 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 and ideal for use in water spray or wash down applications.
Automated calibration and other maintenance procedures are simple and easily performed in the field. For parking garage applications, 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.
