1. Brief introduction:

Fixed-type combustible CH4 gas detector is an instrument designed to detect the presence of flammable gas in the air. It is commonly used in industrial settings where combustible gases are produced or used (such as gas pipelines, petrochemical plants, and oil refineries) to warn workers of potential gas leaks or buildup. The device operates by sensing the concentration of combustible gas in the air and triggering an alarm if the level exceeds a certain threshold. Fixed-type gas detectors are stationary and permanently mounted to a fixed location, providing continuous monitoring of the surrounding environment for potential gas hazards. They are an essential safety tool in many hazardous work environments.

2 . Detailed Introduction:

Xi'an Huafan technology fixed methane CH4 gas detector is generally installed in the workshop and warehouse to form a fixed detection point, which needs to be used in conjunction with the alarm controller. The controller can be placed in the watch room to control the monitoring points. The CH4 Gas Detector is installed in the spot where combustible gas is most likely to leak. Its core component is a built-in combustible gas sensor, which detects the concentration of gas in the air. The detector converts the gas concentration detected by the sensor into an electrical signal and transmits it to the controller through cables. The higher the gas concentration is, the stronger the electrical signal will be. When the gas concentration reaches or exceeds the alarm point set by the alarm controller, the alarm will send an alarm signal and start the electromagnetic valve, exhaust fan and other external devices to automatically eliminate hidden dangers.
