Fixed Gas Alarms
- Brand
- Type
Description:
OC-F08 fixed gas alarm can be connected with various control systems, and has functions of remote monitoring and alarming, data recording and analysis. Using imported sensors, the signal is stable and the response is fast. Gas can be customized.
Common applications is gas safety inspection and alarm for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, metallurgy, mining, fire, environmental protection, etc., where need to inspect the gas concentration.
Features:
4-20mA standard analog signal and RS485 digital signal output, 200~1000HZ signal output, relay output, data restore, data logger (optional);
LED screen displaying the gas concentration, gas type, unit, instrument status etc.
Independent air chamber, the sensor is not required to replace the sensor calibration, automatic identification of key parameters of the sensor
Protection function to prevent high gas concentration attack.
Display the gas concentration in %vol.
Infrared remote controller operation;
With the 16bit ADC acquisition chip, designed with four-layer circuit board, so with high anti-interference ability.
With the Ex-proof certificate, the Ex-proof grade is Exd II CT6.
