Daily application of combustible gas detector
Combustible gas detector When flammable or toxic gas leaks in the industrial environment, when the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the combustible gas alarm will send out an alarm signal to remind the work to take safe measures. Measures are taken, and the exhaust, cut-off, and sprinkler systems are driven to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production.
The principle of combustible gas detector:
Combustible gas detectors are detectors that respond to single or multiple combustible gas concentrations. There are two types of combustible gas detectors: catalytic type and infrared optical type. The infrared optical type uses infrared sensors to detect hydrocarbon combustible gases in the on-site environment through the absorption principle of infrared light sources.
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.
Scope of use of combustible gas detectors:
Combustible gas detectors are mainly used to detect combustible gases in the air, such as hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), butyne (C4H6), Phosphine, ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), propyne (C3H4), etc.
