The ESH Remote Sensor offers flexible location monitoring of catalytic, refrigerant or TVOC gases in non-hazardous, non-explosion rated commercial and light industrial applications. 

 
The ESH Remote Sensor is powered by and communicates with a controller or transmitter using a current loop into a 100 ohm load or a voltage signal of 0.40 to 2 volts. It can be located at a maximum distance of 200 ft from the controller or transmitter.
 
COMPATIBLE CETCI PRODUCTS:
Transmitters 
LPT-A Analog (single channel)
LPT-P Car Park Digital (1, 2 or 3 channel)
LPT-M Modbus (1, 2 or 3 channel)
LPT-B BACnet (1, 2 or 3 channel)
LPT-H Hybrid (single or dual channel)
Controllers
SCC Self Contained (single or dual channel)
DCC Dual Channel (single or dual channel)

 

The sensor is protected in our standard water/dust tight, corrosion resistant ABS/poly-carbonate enclosure which also provides easy mounting components. With the optional splash guard installed, it is IP54 rated and the remote sensor is protected in water spray or wash down applications.
