THE INSTRUMENT

These Single Point Wall Mounted Instruments work on 18-24VDC and have a PESO certified Ex proof sensor housing fitted on an Ex-proof Junction box. They use an IP 55 enclosure for the electronics as standard. They are provided with two alarms both audible and visual along with relays and output of 420 mA. They are meant for continuous operation of area monitoring with continuous read out, plus vital status indicators

FEATURES

Type of sensors that can be connected are Electrochemical, NDIR, Pellistor, and Thermal conductivity depending on gas and application.

APPLICATIONS

Used in Hazardous areas for Group IIA, IIB or Group IIC gases. Zone 1 and Zone 2 for gas sensing with appropriate sensor in conjunction with the necessary FLP enclosures for instrumentation or wiring, for detection of toxic or flammable gases in work places or enclosed spaces for safety. Measurement of Hydrogen in battery rooms .
