Combustible gas alarm device according to the use of the environment can be divided into industrial combustible gas alarm device and household gas alarm device, according to its own form can be divided into fixed combustible gas alarm device and portable combustible gas alarm device.
Fixed combustible gas alarm instrument is generally composed of alarm controller and detector, the controller can be placed in the duty room, mainly for the control of the monitoring point, the detector is installed in the combustible gas is most likely to leak the location of the core components for the built-in combustible gas sensors, sensors to detect the concentration of gas in the air. The sensor detects the gas concentration in the air. The detector converts the gas concentration detected by the sensor into an electric signal and transmits it to the controller through the cable. The higher the gas concentration is, the stronger the electric signal is; when the gas concentration reaches or exceeds the alarm point set by the alarm controller, the alarm sends out an alarm signal, and it can activate the solenoid valve, the exhaust fan and other outreach equipments to eliminate the hidden dangers automatically.
Portable combustible gas alarm for handheld, staff can carry, detecting different locations of the combustible gas concentration, portable gas detector set of controllers, detectors in one. Compared with fixed gas alarm, the main difference is that portable gas detector can not be connected to other equipment.
