Description
Technical Field
The invention relates to a fixed gas detector, in particular to a multifunctional fixed gas detector.
Background
At present, in an explosive gas detection environment, the types of gas detection equipment are more, and the application of a fixed gas detector is increasingly wide. The gas detector is normally powered by a DC24V DC power source, and the detector is powered by a UPS in a control room through an explosion-proof hose, but some field environment equipment is single, has no UPS, and only has an AC22V AC power source, and when the detector is powered, a control box with higher cost needs to be installed firstly to convert AC220V into DC 24V.
