What is a combustible gas monitor? What is it used for?
In our daily lives, there are actually a lot of flammable gases. The harm of these flammable gases has caused major problems in public safety over the years. Therefore, to effectively avoid the harm caused to us by combustible gases, we need to use a gas detector, that is - a combustible gas detector.
A combustible gas detector is a detector that responds to single or multiple combustible gas concentrations. 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 combustible gas enters the detector, it causes an oxidation reaction (flameless combustion) on the surface of the platinum wire. The heat generated increases the temperature of the platinum wire, and the resistivity of the platinum wire changes.
The combustible gas detector is a combustible gas explosion-proof detector with display and digital signal output. Each gas detector only detects one type of gas. The gas detector is an industrial combustible gas safety detection instrument among industrial gas leakage detection and alarm devices. It can be fixedly installed in indoor and outdoor dangerous places where the gas to be measured leaks. It plays the role of on-site monitoring. If there is a leak of flammable gas at the monitoring location, the gas detector will quickly transmit the leaked flammable and explosive gas concentration data to the gas alarm controller, which will be controlled by the gas alarm. processor for data processing.
In daily life, combustible gas detectors are mainly used for gas detection in industrial environments. In the form of a detector plus a controller, in the factory, the detection data of the detector is received and displayed on the controller. A single monitoring person can monitor a wide range of environmental testing in the factory, and at the same time, start the exhaust device or close the solenoid valve to cut off the air source to achieve safety. Combustible gas alarms, gas alarms, gas alarms, and gas detectors are installed at explosion-proof sites; the controller is wall-mounted in guarded places such as duty rooms, and the two are connected using shielded cables.
