Gas Alarm System for Detection of Flammable or Toxic Gas Leaks in Industrial Environments
Product Profile
AQMS-02 Gas Alarm System adopts imported intelligent gas sensor with high sensitivity and precision. The product is used to detect the leakage of combustible or toxic gases in industrial environment. The whole detector adopts flameproof structure to ensure safety.
Advantages
Imported high-performance sensors have high measurement accuracy, good repeatability and long service life.
Adopt independent 16-bit AD chip and 4-layer circuit board design, which has stronger anti-interference ability.
The units of mg/m3, ppm, VOL and LEL can be selected.
The embedded 32-bit ultra-low power processor is adopted, and the response speed is fast.
Automatic protection against high concentration gas.
It has the function of restoring factory settings to prevent misoperation.
The instrument is equipped with infrared remote controller, which is easy and convenient to operate without opening the cover.
Three-wire 4-20mA, RS485 signal output optional, relay output.
The explosion-proof grade is Exd II CT6, certified by the national explosion-proof electrical inspection center.
Applications
Petroleum and petrochemical, metallurgy, environmental protection, gas, fire protection, municipal administration, chemical industry, shipping, electric power, process control, sewage treatment, emergency rescue monitoring and other industries.
