Overview
SK/MIC-600-CH2O-Y/2000 On-line Formaldehyde detector is a fixed installation gas concentration monitoring equipment of SKYEAGLEE brand. The instrument 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. Full software Adjustment, users can calibrate 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 formaldehyde (CH2O) 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, it 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.
Standards
Explosion-proof mark: ExdIICT6, Protection Rating: IP66
Steps
1. Install the fixed detector and connect the power supply and signal cable as required.
2. Connect DC12~ 30V Power Supply.
3. After the instrument is powered on, confirm the working status through the point matrix LCD display.
4. If you need to calibrate, use the 3 buttons on the instrument to enter the calibrate mode, and follow the prompts to calibrate the zero point and range.
5. According to actual needs, configure alarm points and Output signal parameters through the settings menu.
6. After setting up, the instrument enters a continuous monitoring state.
Notice
Installation and wiring must be carried out by professionals to ensure compliance with explosion-proof requirements.
* Working ambient temperature range is -20 ℃~ + 50 ℃, Humidity should be ≤ 90% RH and no condensation.
It is recommended to use a single three-core Shielding cable with a wire diameter of ≥ 1.5mm, and the connection distance should not exceed 1000 meters.
* Sensors have a lifespan of approximately 2 years and require regular maintenance and calibrating to ensure detection accuracy.
* Avoid instrument from high concentration gas Impact to take advantage of its automatic protection function.
* When selecting, please confirm according to the actual working conditions (such as gas type, range, Installation method, etc.).
