TGas-1031 Series Combustible, Toxic and Harmful Gas Transmitter
TGas-1031 Series Combustible, Toxic and Harmful Gas Transmitter can continuously measure the concentration of site gas, and convert the concentration signal into 4-20mA output. It is extensively applied in petroleum, petrochemistry, chemical industry, gas, coal, metallurgy and electric power; safety detection in municipal administration, telecommunication and traffic tunnel construction; the place where combustible, poisonous and harmful gas might leak, such as gasholder station and special industrial factory building, etc.
Main features
l Two kinds of optional mode of power supply, including centralized busbar type and independent area type
l High and low concentration alarm, performing real-time monitor to gas
l Anti-poisoning type gas sensor with high sensitivity
l Automatic modification of ageing curve of sensor, keeping constant alarm sensitivity
l Function of automatic recognition of sensor trouble, function of high concentration gas above-norm of sensor
l Function of automatic detection at starting up, and it has advanced function of self-diagnosis and self-reparing.
l The calibrated concentration value is adjustable, facilitating users to set by themselves
l When the sensor loses the function of monitoring alarm because of ageing, the detector is capable of automatic recognition and alarm, so as to effectively avoid missing report.
