Overview
SK/MIC-600-NH3-Y/5000 online ammonia gas 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 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, intelligent Sensor detection technology, the whole is 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 uses the Sensor of electrochemistry principle to continuously monitor the ammonia (NH3) concentration in the environment through the Sampling method of diffusion, pipeline, flow or pump (optional). The Sensor converts the gas concentration signal into an electrical signal, and after internal processing, 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 instrument is powered on, the reading is observed 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 requirements, configure alarm points and Output signal parameters through the settings menu.
Notice
* Please select the model according to the actual working conditions, the information is for reference only.
* Working ambient temperature range is -20 ℃~ + 50 ℃, Humidity is 10% RH~ 90% RH (no condensation).
The working pressure is 106KPa +/- 20KPa.
It is recommended to use a single wire diameter ≥ 1.5mm three-core Shielding cable for connection, with a maximum connection distance of ≤ 1000 meters.
* Sensors have a lifespan of approximately 2 years and require regular maintenance and calibrating.
* Instrument Protection Rating is IP66, but care should be taken to avoid long-term exposure to extreme environments when installing.
* Alarm point can be set as needed, output 2 passive node signal.
