Mainstream equipment adoptsNDIR Non-dispersive infrared sensor, compared with electrochemical sensors, it has advantages of strong anti-interference, no gas poisoning, long service life, small zero drift, and is not affected by conventional environmental factors such as oxygen, water vapor, and dust. The detector uses diffusion sampling, wall-mounted installation,DC24V Industrial power supply.
Core functions: real-time digital display of gas concentration, supports high and low two-level alarms, alarm threshold customizable; after triggering alarm, local sound and light prompt, simultaneously outputs 4-20mA Analog signal,RS485 Modbus communication signal and relay passive switch signal, can link exhaust fan, refrigerant cut-off solenoid valve, connect to PLC、BA Building automation,SCADA system, realizing remote monitoring and automated emergency response.
The housing is mostly cast aluminum alloy explosion-proof shell, explosion-proof rating Ex d II CT6, protection rating IP65/IP66, dustproof and waterproof, adapts to - 20℃～+50℃、10%～95% RH(no condensation) machine room working conditions. Range optional 0~500ppm To 0~2000ppm, detection accuracy ±5% FS, fast response, supports networking of multiple detectors, some models can store alarm records, convenient for operation and maintenance traceability.
