Principle
Electrochemical sensor is used to continuously monitor the target gas through diffusion, pipeline, flow or pump sampling methods. The sensor converts the gas concentration signal into an electrical signal, and outputs a standard 4-20mA current signal or RS485 digital signal through internal circuit processing. Real-time concentration can be displayed through point array LCD screen.
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.
Steps
1. According to the installation requirements, choose the appropriate location to install the detector fixedly.
2. Connect the power supply (DC12~ 30V) and signal output line (three-core cable, Shielding cable is recommended) according to the electrical wiring definition diagram.
3. After power on, the instrument is initialized to observe whether the LCD display is displayed normally.
4. If you need to calibrate, you can enter the calibrate mode through the 3 buttons on the instrument, and follow the prompts to calibrate at zero and full scale.
5. According to actual needs, set parameters such as alarm points through buttons or communication.
6. The instrument enters the normal working state, continuously monitors the gas concentration, and outputs data through 4-20mA or RS485 signal.
Notice
• Please select according to the actual working conditions to ensure that the detection gas, range and environmental conditions match.
• When installing, ensure that the working Ambient Temperature is -20 ℃~ + 50 ℃, Humidity is 10% RH~ 90% RH without condensation, and absolute pressure is within the range of 106KPa +/- 20KPa.
• It is recommended to choose a single Shielding cable with a diameter of ≥ 1.5mm for connecting cables, and the connection distance should be ≤ 1000m.
• The instrument is explosion-proof and explosion-proof equipment, and the installation, use and maintenance must strictly abide by the relevant regulations on explosion-proof electrical equipment.
• Sensors have a lifespan of about 2 years and require regular calibrating and maintenance to ensure detection accuracy.
• Avoid the instrument from being directly impacted by high concentrations of gases to prevent damage to the Sensor.
When calibrating, use standard gas and operate in a safe environment.
