Product Description

Description:

Gas detector CRH-80 series is a new type gas combustible gas detector which used high performance catalytic combustion gas sensor and microcontroller technology. It has following advantages: good repeatability, high resistance to humidity-temperature jamminglong performance life and simple operation. It is applied to inspection for combustible gas concentration in industrial environments

 

It can translate the combustible gas concentration signals into electric current signals or digital signals for outputting and transmitting. It adopted three-wire (4~20mA signals output) or four-wire (RS485 bus output) system, remotely examine the detection result through the monitor or controller. Common applications is gas safety inspection and alarm for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, etc.

 

Features:

High sensibility, rapid response, short polarization time;

4-20mA standard analog signal or RS485 digital signal output;

Two-level passive contact output;

Infrared remote controller operation (remote controller is optional part);

Possible to connect to DCS system directly;

Explosion-proof design complies with the requirement of applying in Zone 1,2.
