HCL leak gas detector hydrogen chlorine alarm detector with 4-20mA output
HCL leak gas detector hydrogen chlorine alarm detector with 4-20mA output
Product Overview:
KQ500D series gas detector with LED display transforms the gas density in the operating site into standard electric current signal(4-20mA).
KQ500D has excellent performance, stable operation, easy maintenance. since detector also can detect various gas, it meet various requirements in the operation site; it has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
Main features:
l Standard 4-20mA electric current output, compatible with existing alarm control unit or DSC (distributed control system).
l LED site display
l Standard three buttons: so an individual can operate the detector in site.
l Automatic identify and display the sensor failures, and output the corresponded current signal at the same time.
l The key operation needs to input password to prevent wrong operation.
l Simple calibration function; reducing measuring error
l Two levels' light alarm, relay output (connected with audible and visual alarm outside or start the exhaust system)
