Overview
SK/MIC-600-NO2-Y/20 on-line nitrogen dioxide detector is a fixed installation gas concentration monitoring equipment of SKYEAGLEE brand. The instrument adopts Modular design, intelligent Sensor detection technology, and has an overall explosion-proof (d) structure. Standard configuration includes point array LCD liquid crystal display, three-wire 4~ 20mA analog and RS485 digital signal output, and can customize programmable switching volume output and other modules according to user requirements. Output signal fine-tuning is supported, which is convenient for system networking and maintenance.
Features
1. Modular design and intelligent Sensor detection technology.
2. Equipped with an integral flameproof (d) structure, suitable for use in hazardous locations.
3. Automatic temperature compensation, and zero point and full scale drift compensation function.
4. Impacts against high concentration gases with automatic protection function.
5. Support full software calibrate, users can calibrate by themselves through 3 buttons, easy to operate.
6. Provide 2-wire 4-20mA Output signal.
Principle
The detector adopts the Sensor of electrochemistry principle, and works continuously through the Sampling method such as diffusion type, pipeline type, flow type or pump type to detect the concentration of nitrogen dioxide gas in the environment and convert it into a standard 4-20mA current signal output.
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. Wire the equipment according to the electrical wiring definition diagram.
2. Connect DC12~ 30V Power Supply.
3. After the instrument is powered on, the reading is observed through the point matrix LCD liquid crystal display.
4. If you need to calibrate, you can enter the calibrate mode through the 3 buttons on the device to operate.
5. Set the alarm point according to the requirements, and configure the passive node signal output.
