Brief Introduction 

TGas-1031 on-line gas transmitter which adopts high performance sensor unit can continuously measure the concentration of gas on site and convert the concentration signal into digital or analog signal output(4-20mA analog signal,RS485 communication signal and switch quantity alarm signal to transmit remotely and drive). 

It is widely used in such industries such as petroleum, chemical, natural gas, coal, metallurgy, electric power, municipal administration, telecom,tunnel construction,gas storage station, special plants and other places where flammable gases or toxic and harmful gases exist. 

Main Features

Two kinds of optional mode of power supply, including centralized busbar type and independent area type

High and low concentration alarm, performing real-time monitor to gas

Anti-poisoning type gas sensor with high sensitivity 

Automatic modification of ageing curve of sensor, keeping constant alarm sensitivity

Function of automatic recognition of sensor trouble, function of high concentration gas above-norm of sensor

Function of automatic detection at starting up, and it has advanced function of self-diagnosis and self-reparing

The calibrated concentration value is adjustable, facilitating users to set by themselves

When the sensor loses the function of monitoring alarm because of ageing, the detector is capable of automatic recognition and alarm, so as to avoid missing report effectively           Technical Parameters
