OC‑F08 Fixed N2 Detection Device is industrial‑grade fixed nitrogen gas monitor, equipped with imported sensor and 32‑bit ultra‑low‑power microprocessor. It measures nitrogen concentration or monitors oxygen deficiency caused by N₂ displacement. It supports 4‑20mA, RS485 and relay output, connects to PLC/DCS system, realizes real‑time monitoring, remote alarm and data logging for inert gas protection in industrial sitesAlibaba
Description:
OC-F08 fixed gas detection device can be connected with the control system, with remote monitoring alarm, analysis function and data recording function. Imported sensors are adopted, with high precision, good repeatability, stable signal and fast response. 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.
