toxic gasinfraredinfrared

The GF-130 gas detector with display gas detection transmitter can be used in places where flammable and explosive gases leak and chemical plants where they are toxic and harmful. The instrument adopts high-performance sensor technology. The product has the advantages of stable signal and high precision. The instrument shell is made of cast aluminum explosion-proof and flameproof design, and the wiring method is suitable for various dangerous places. HIGHLIGHTS High detection accuracy, adjustable range. Long service life, high sensitivity, low drift, and stable and reliable operation. Self-detection of sensor faults, two-level concentration alarm, with relay output function. Digital display of gas concentration and working status on LCD or digital tube. Has temperature compensation and automatic zero-point correction functions 4-20mA standard signal output or RS485 digital output, can be uploaded to DCS and PLC systems Infrared remote control mode. The detector can be adiusted without opening the cover Three proof design, intrinsic safety circuit APPLICATION The point-type gas detector is suitable for industrial sites with gases such as oil refineries, chemical plants, liquefied gas stations, gas-fired boiler rooms, refueling and gas filling stations, and spray painting rooms to carry out gas safety detection and alarm SPECIFICATIONS Detection principle - Catalytic, semiconductor, infrared, PID Sensor Gas sampling - Natural diffusion Indication method - 4-digit LED light Operation - Infrared remote control operation Working temperature - -40℃-70℃ (combustible gases),-20℃-50℃ (toxic gases) Working humidity - ≤93%RH Power supply - DC24V Switch quantity - 2 (two alarm points often open)
