Overview
SK/MIC-600-H2S-Y/40000 online hydrogen sulfide detector is a fixed installation gas concentration monitor 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 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, 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 signal.
Principle
The detector adopts the Sensor of electrochemistry principle to continuously monitor hydrogen sulfide (H2S) gas 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, uses 4-20mA current signal and 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 marking: ExdIICT6
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, observe the 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 instrument to operate.
5. Set up alarm points in Control system (such as PLC, computer) according to requirements.
Notice
