Overview
SK/MIC-600-SO2-Y/2000 online sulfur dioxide detector is a fixed installation gas concentration monitoring equipment of SKYEAGLEE brand. The product adopts Modular design, intelligent Sensor detection technology, and the whole is explosion-proof (d) structure. Standard configuration includes point array LCD liquid crystal display, three-wire 4~ 20mA analog signal and RS485 digital signal output, and can customize programmable switch output and other modules according to user request, support Output signal fine-tuning, easy system networking and maintenance.
Features
1. Modular design is adopted to support customized configuration.
2. Sensor detection technology.
3. Integral flameproof (d) structure, suitable for use in hazardous locations.
4. Automatic temperature compensation, zero point and full scale drift compensation.
5. Impacts against high concentration gases with automatic protection function.
6. Support full software calibrate, users can calibrate by themselves through 3 buttons, easy to operate.
7. Provide 2-wire 4-20mA output.
Principle
The detector adopts the Sensor of electrochemistry principle to continuously monitor the concentration of sulfur dioxide (SO2) in the environment through Sampling methods such as diffusion type, pipeline type, flow type or pump type. The Sensor converts the gas concentration signal into an electrical signal, and after processing by the internal circuit, it uses 4-20mA current signal and digital signal output, and can display the concentration value in real time through the LCD display screen.
Applications
Paints room, incineration plant, 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
Standards
Explosion-proof mark: ExdIICT6, Protection Rating: IP66
Steps
1. Wire the equipment according to the electrical wiring definition diagram.
2. Connect DC12~ 30V Power Supply.
3. After the device is powered on, confirm the device status and reading 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, and follow the prompts to calibrate the zero point and range.
5. According to actual needs, set parameters such as alarm points through the supporting system.
6. The device starts continuous monitoring and can be output to the Control system through 4-20mA or RS485 signal.
Notice
• Please select the appropriate range and Sampling method (diffusion type, pipeline type, flow type, pump suction type) according to the actual working conditions.
• Installation and wiring must meet explosion-proof requirements. It is recommended to use a single three-core Shielding cable with a wire diameter of ≥ 1.5mm.
• Equipment working ambient temperature range is -20 ℃~ + 50 ℃, Humidity range is 10% RH~ 90% RH (no condensation).
• Sensors have a lifespan of about 2 years and require regular maintenance and calibrating to ensure detection accuracy.
• Impact equipment from high concentrations of gases to take advantage of its automatic protection function.
The maximum connection distance is recommended to be no more than 1000 meters.
