What is a flammable gas detector? What is it used for?
In our daily lives, there are actually many combustible gases present, and the hazards of these gases have become a major issue in public safety for many years. Therefore, to effectively avoid the harm caused by combustible gases, we need to use a gas detector, which is a combustible gas detector.
A combustible gas detector is a detector that responds to the concentration of a single or multiple combustible gases. There are two types of combustible gas detectors: catalytic type and infrared optical type. Catalytic combustible gas detector uses the resistance change of refractory metal platinum wire after heating to determine the concentration of combustible gases. When 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, causing a change in its electrical resistivity.
Combustible gas detector is an explosion-proof type detector with display and digital signal output. Each gas detector is only used for detecting one type of gas. Gas detectors are industrial combustible gas safety detection instruments used in industrial gas leak detection and alarm devices. It can be fixedly installed in indoor or outdoor hazardous areas with gas leakage under test. It plays a role in on-site monitoring. If there is a flammable gas leak at the monitoring location, the gas detector will quickly transmit the concentration data of the leaked flammable and explosive gases to the gas alarm controller for data processing.
In daily life, combustible gas detectors are mainly used for gas detection in industrial environments. In the form of a detector and a controller, the detection data of the detector is received and displayed on the controller in the factory. One or two monitoring personnel can monitor the large-scale environmental detection of the factory, and at the same time, the exhaust device can be activated or the electromagnetic valve can be closed to block the gas source for safety purposes. Combustible gas alarm, gas alarm, gas detector detector, installed on explosion-proof sites; The controller is wall mounted in manned areas such as the duty room, and the two are connected using shielded cables.
