Overview
SK/MIC-600-H2S-Y/100 online hydrogen sulfide detector is a fixed installation gas concentration monitoring equipment of SKYEAGLEE brand. The instrument adopts Modular design, intelligent Sensor detection technology and overall flameproof (d) structure, standard configuration with dot matrix LCD liquid crystal display, supports three-wire system 4~ 20mA analog and RS485 digital signal output, and can customize programmable switch output and other modules according to user request, which is convenient for system networking and maintenance.
Features
1. Modular design is adopted to support customization.
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. Full software Adjustment, users can calibrate themselves through 3 buttons, easy to operate.
7. Support 2-wire 4-20mA output.
Principle
The detector uses a fixed continuous operation mode to monitor hydrogen sulfide (H2S) gas in the air through diffusion, pipeline, flow or pump-suction (optional) sampling. After the sensor detects the gas concentration, the signal is converted into a standard 4-20mA current signal or RS485 digital 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.
Standards
Explosion-proof mark: ExdIICT6, Protection Rating: IP66
Steps
1. Wire 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 array LCD LCD screen.
4. If you need to calibrate, you can enter the calibrate mode through the three buttons of the instrument, and follow the prompts to calibrate the zero point and range.
5. According to requirements, configure alarm points and Output signals through the settings menu.
