  • Easy to to install and maintain
  • Standard water / dust tight, corrosion resistant enclosure (drip proof)
  • IP54 rated with optional splash guard installed

 Description
The ESH-A Remote Sensor offers flexible location monitoring of combustible gases or PID TVOCs in non-hazardous, 
non-explosion rated, commercial and light industrial applications. It communicates with the device it is attached to 
using 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 meters from the compatible controller or transmitter.
The mounting height of the ESH-A Remote Sensor depends on the gas being monitored. A gas that is heavier than 
air should be detected 6 inches from the floor and a gas that is lighter should be detected on or near the ceiling.
A gas that has the same density as air should be detected in the “breathing zone”, where most human breathing
takes place, which is 1 to 2 m (4 to 6 ft) from the floor.
The ESH-A Remote Sensor comes in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure 
with a hinged, secure door and is designed to protect the sensor and provide easy mounting components.
An optional splash guard may be installed to further protect the remote sensor in water spray or washdown 
applications.
The ESH-A Remote Sensor is not a standalone device, it must be used with the SCC, DCC, LPT-A, LPT-P, LPT-M, 
LPT-B or CGAS-D (remote sensor's target gas will differ based on device).
