What is a combustible gas detector? What is the use
In our daily life, there are actually a lot of combustible gases. The harm of these combustible gases has formed a major problem in public safety for many years. Therefore, in order to effectively avoid the harm caused by combustible gas, we need to use a gas detector, that is, a combustible gas detector.
The combustible gas detector is a detector that responds to the concentration of single or multiple combustible gases. There are two types of combustible gas detectors: catalytic type and infrared optical type. The catalytic combustible gas detector uses the resistance change of the refractory metal platinum wire after heating to measure the concentration of combustible gas. When the combustible gas enters the detector, it causes an oxidation reaction (flameless combustion) on the surface of the platinum wire, and the heat generated increases the temperature of the platinum wire, and the resistivity of the platinum wire changes.
The combustible gas detector is an explosion-proof combustible gas detector with display and digital signal output. Each gas detector is only for one kind of gas detection. The gas detector is an industrial flammable gas safety detection instrument in the industrial gas leakage detection and alarm device. It can be fixedly installed in indoor and outdoor dangerous places where the gas to be tested leaks. It plays the role of on-site monitoring. If there is a flammable gas leakage at the monitoring location, the gas detector will transmit the concentration data of the flammable and explosive gas leaked on site to the gas alarm controller within a very short time, and the gas alarm will control it. processor for data processing.
In daily life, combustible gas detectors are mainly used for gas detection in industrial environments. In the factory, in the form of detectors and controllers, the detection data of the detectors are received and displayed on the controller. A single monitoring person can monitor a wide range of environmental inspections in the factory, and at the same time can activate the exhaust device or close the solenoid valve to block the air source to achieve the purpose of safety. Combustible gas alarms, gas alarms, gas alarms, and gas detector detectors are installed at the explosion-proof site; the controller is wall-mounted in the duty room and other manned places, and the two are connected by shielded cables.
