product description

Product description:

Acrylonitrile is a colorless, pungent odor liquid, which is flammable. Its vapor can form explosive mixture with air. In case of open flames or high heat, it is easy to cause combustion and emit toxic gases. Reacts violently with oxidants, strong acids, strong bases, amines, and bromine. Flammable, its vapor can form explosive mixture with air. In case of open flames or high heat, it is easy to cause combustion and emit toxic gases. Reacts violently with oxidants, strong acids, strong bases, amines, and bromine. At the high temperature of the fire, polymerization and exotherm can occur, which can cause the container to rupture.

On-line acrylonitrile gas alarm, suitable for real-time and accurate detection of acrylonitrile gas concentration and leak in various environments, using electrical detection principle sensor and microcontroller technology. Fast response speed, high measurement accuracy, stability and repeatability Good and other advantages. Explosion-proof wiring method is suitable for various hazardous locations, and is compatible with various control alarms, PLC, DCS and other control systems. It is widely used in petrochemical, industrial production, smelting and forging, power, coal mine, tunnel engineering, environmental monitoring. , Sewage treatment, bio-pharmaceuticals, household environmental protection, livestock breeding, greenhouse cultivation, warehousing and logistics, brewing and fermentation, agricultural production, fire protection, gas, building construction, municipal enterprises, school laboratories, scientific research centers and other industries.

Industrial fixed acrylonitrile detection probes consist of an alarm controller and an acrylonitrile detector. The alarm controller can be placed in the duty room and mainly controls various monitoring points. The acrylonitrile detector is installed in the place where the gas is most likely to leak. The core component is a built-in gas sensor that detects the concentration of gas in the air. The detector converts the acrylonitrile concentration detected by the sensor into an electrical signal and transmits it to the controller through the cable. The higher the gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the alarm controller, the alarm The alarm signal is issued, and external devices such as solenoid valves and exhaust fans can be activated to automatically eliminate hidden dangers. Fixed chlorine dioxide detection probes are widely used in petroleum, chemical, metallurgy, electric power, coal mines, water plants and other environments to effectively prevent accidents such as poisoning and explosions.
