Specifications
Single Gas detector
Replaceable modularized sensor
Wall-mounted //4~20mA SIGNAL
Online monitor
Stand alone gas detector
Product Overview:
TR series single channel wall-mounted gas detector can be used continuously in operation environment to detect the concentration of combustion gas, oxygen, and toxic gas.
The gas detector detects gas concentration in natural diffusion way, and uses electric chemical sensor or catalytic combustion type sensor; big LCD displays the concentration of the leaked gas real time.
If the concentration exceeds the preset alarm level, detector will start the acoustic-optical alarm or exhaust system; international standard signal of 4-20mA can be directly connected into the factory DCS system, RS4845 digital signal is connected with factory’s principle computer; the device adopts embedded micro controlling technique.
Stand-alone gas detector: AC 220V
Main features:
l Adopts advanced embedded micro controller(16 digit ultra-low power consumption )
