The LPT-B is a full featured, 1, 2 or 3 channel, digital transmitter for use in non-hazardous, non-explosion rated, commercial and light industrial applications. It is available with a wide range of internal and/or external sensors and sensor types including electrochemical, solid state, catalytic and PID. The LPT-B may be configured to operate as a standalone fixed system or be part of a digital network. It offers a BACnet® MS/TP output signal for communicating with a Controller or Building Automation System, an audible internal alarm, one SPDT dry contact relay, LCD display with user selectable functions, temperature compensation and thermal resetting fuses all in a RoHS compliant package. 
 
The LPT-B comes in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door. It is IP54 rated with the optional splash guard installed which provides protection in water spray or wash down applications. An optional heater is available for continued operation in cold environment applications.
 
The LPT-B is not compatible with CETCI’s Controllers. It is intended to be used alone or integrated into an existing BACnet® network.
