Introduction
BH-60 fixed Gas Detector is a new type of Gas Detector developed and produced based on the company's many years of experience in gas detection. It is used to detect the concentration of flammable gases or other toxic and harmful gases in the air. When the concentration reaches or exceeds the preset alarm value The controller will send out an audible and visual alarm to remind you to take safety measures in time to prevent explosion and poisoning accidents, thereby ensuring the safety of life and property.
This product has the advantages of stable signal, high precision, quick response, long life, short polarization time, etc. It adopts industrial-grade sensor, and the instrument shell adopts explosion-proof and explosion-proof structure design. The 4-20mA standard signal or directly enters the DOS system, which can be widely used. In metallurgy, petroleum, chemical industry, municipal and other industries, it is at the professional level of similar products in CHINA.
The shell adopts a die-cast aluminum shell with a flameproof structure design. The groove design of the upper cover can lock the shell. The front of the sensor is designed as a downward structure to ensure good contact between the sensor and the gas. The cable inlet adopts an explosion-proof waterproof connector.
