OC-F08 series online gas detector used the original imported sensor
and the ultra low power 32 bit microprocessor, so with the
advantages of high precision, good repeatability, stable signal,
respond quickly, etc. Possible connected with many controller
system, such as PLC, DCS, computer and other, with the function of
remote monitor and alarm, data logger and analysis.
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.
Features of the Fixed combustible gas detector:
4-20mA standard analog signal and RS485 digital signal output,
200~1000HZsignal output, relay output, data restore, data
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
Protection function to prevent high gas concentration attack.
Display the gas concentration in %LEL.
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.
