KQ500D intelligent gas detector is a kind of wall-mounted type detector that can be used continuously in operation environment to detect the concentration of combustion gas, oxygen, and toxic gas. The detector detects gas concentration in natural diffusion way.
KQ500D intelligent gas detector 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.
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 (optional LCD 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)
