KQ500D series fixed gas detector is also called gas sensor.It transforms the gas density in the operating site into standard electric current signal(4-20mA). With LED display, detector's sensor can be changed and reused as soon as it is connected to electricity.
KQ500D detector has excellent performance, stable operation, easy maintenance. detector 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 that is suitable for factory
l Standard three buttons: so an individual can operate the detector on site.
l Automatic identify and display the sensor failures, 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 & visual alarm outside or start exhaust system)
