Product Description
Function:
The sampled gas first passes through the filter, filters dust and impurities, and then passes through the sampling pump to the electronic condenser (the electronic condenser is mainly used for cooling and dehumidification to avoid secondary condensation of water vapor due to temperature, semiconductor condensation dehumidification, and condensation of humidity water vapor into water for discharge). The flow rate of the extracted gas is controlled by the flow meter (the flow rate of the flow meter is generally controlled at 0.3~0.5L/Min), Finally, in the instrument detection (the working environment of the instrument needs to be used in the working condition of -20 ° ~ 60 °), the water produced by the filter can be automatically drained by the peristaltic pump.
Consumables:
The service life of the sensor is about 1 to 3 years, which is a consumable, and the specific use time is determined according to the detection environment.
2. The color of the chip inside the filter changes and needs to be replaced. The service life is about 3 months, depending on the detection environment.
3. The sampling air pump has a service life of about 1 year and the peristaltic pump has a service life of about 1 year.
Features:
1. Detector detection principle: electrochemical, imported sensors, using intrinsic safety technology, can support multi-gas, multi-range detection, and can provide customized products according to user needs, without tools to achieve sensor exchange, offline calibration and zero self-calibration
2. A variety of signal output, which can be easily connected to PLC/DCS and other industrial control systems, can also be used as a stand-alone control (switch output, RS485 output, 4-20mA output)
3. Local alarm indication, integrated sound and light detector (optional)
4. The instrument has over-range and reverse polarity protection, which can avoid the danger caused by improper operation
5. Cooling and dehumidification of condenser to avoid secondary condensation of water vapor
6. Peristaltic pump with time relay timing drainage
7. Dust filter, filter dust, when there is water, stored with peristaltic pump for discharge
8. Sampling pump, the longest sampling distance can reach 100 meters, it is recommended to be within 20 meters
9. Flow meter, control the gas flow rate, avoid the gas flow too fast to wash the sensor
10. Seven-inch LCD large screen, 1000 historical alarm records, 100000 historical data, adjustable historical data storage interval
