Principle
Electrochemical sensor is used to continuously monitor hydrogen through diffusion, pipeline, flow or pump sampling methods. Sensor converts the gas concentration signal into electrical signal, and can output 4-20mA current signal and RS485 digital signal after processing.
Applications
Paints room, incinerator, scientific research, production workshop, company, environment monitoring, school scientific research, building construction, fire alarm, sewage treatment, industrial gas process control, petroleum and petrochemical, chemical plant, smelter, steel plant, coal plant, thermal power plant, boiler room, waste treatment plant, tunnel construction, oil pipeline, gas station, underground gas pipeline maintenance, indoor air mass detection, safety protection equipment monitoring in dangerous places, etc.
Standards
Explosion-proof marking: ExdIICT6
Steps
1. Installation: Select the fixed Installation method according to the site needs, connect the cable (Shielding cable is recommended, single wire diameter ≥ 1.5mm).
2. Wiring: Connect the power supply (DC12~ 30V) and Output signal line (4-20mA, etc.) according to the electrical wiring definition diagram.
3. Power on: Power on, the device starts and performs self-test.
4. Calibrate: Enter the calibrate mode through the 3 buttons on the device, and use the standard gas to calibrate the zero point and range.
5. Settings: Set parameters such as alarm points as needed.
6. Operation: The device starts to continuously monitor, the LCD screen displays real-time concentration, and outputs corresponding signals.
