Description
Acrylonitrile ppm detector – flameproof, fixed, ATEX, Zone 1, 2
online, continuous measurement and alarm of toxic level (ppm range) of acrylonitrile gas / vapour in air or gas stream ducts, flameproof / explosion proof certified Zone 1, 2 – ATEX, with / without display, contact relays, flashing alarm LEDs, RS485 serial interface with Modbus RTU protocol
Model: XGST-007
Acrylonitrile is a colorless, liquid, man-made chemical with a sharp, onion- or garlic-like odor. It can be dissolved in water and evaporates quickly. It is a highly poisonous compound used widely in the manufacturing plastics, adhesives , synthetic rubber, and acrylic fibers.
Acute (short-term) exposure of workers to acrylonitrile has been observed to cause mucous membrane irritation, headaches, dizziness, and nausea.
XGST series acrylonitrile sensor transmitter is high sensitive, industrial grade, explosion proof detector toxic range ppm measurement. It is suitable for installed hazardous zone 1, 2 classified area as per OSHA, WHO worksafety requirement. Eg. chemical plant, solvent manufacturing unit, polymer industry, manufacturing plants, warehouse etc
The detector comes with universal mounting, hence can be installed at walls, surfaces or in ducts.
It offer linear, proportional analog output in industry standard current signals, and suitable for integration with BMS, SCADA system. It has unique feature of auto diagnostic watch dog with zero point tracking feature. Due to its 10-bit microprocessor based control unit, it offer high accuracy over long term. The detector is also equipped with sintered filter with flashback arrestor for enhanced safety.
