Overview
SK/MIC-600-SO2-Y/20 online sulfur dioxide detector is a fixed installation gas concentration monitoring equipment of SKYEAGLEE brand. The instrument adopts Modular design, with intelligent Sensor detection technology, and the whole is explosion-proof (d) structure. Standard configuration includes LCD with dot matrix, 3-wire 4~ 20mA analog signal and RS485 digital signal output, and can customize programmable switch output and other modules according to user request. Output signal fine-tuning is supported, which is convenient for system networking and maintenance.
Features
1. Modular design, intelligent Sensor detection technology, the overall flameproof (d) structure.
2. With automatic temperature compensation, zero point and full scale drift compensation function.
3. Impact protection against high concentration gases.
4. Support full software calibrate, users can calibrate by themselves through 3 buttons, easy to operate.
5. Provide 2-wire 4-20mA output.
Principle
The detector adopts the Sensor of electrochemistry principle to continuously monitor the concentration of sulfur dioxide gas in the environment through Sampling methods such as diffusion, pipeline, flow or pump suction. The Sensor converts the gas concentration signal into an electrical signal, and after processing by the internal processing circuit, uses 4-20mA current signal and RS485 digital signal output, and can display the concentration value in real time through the LCD display 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. Wire the equipment according to the electrical wiring definition diagram.
2. Connect DC12~ 30V Power Supply.
3. After the instrument is powered on, confirm the normal operation of the device 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 instrument, and follow the prompts to calibrate the zero point and range.
5. According to the actual needs, set the alarm point through the system.
6. Equipment starts continuous monitoring, can be connected to PLC, DCS or computer Control system through Output signal.
