Operation process

The sampled gas first passes through the filter, filters dust and impurities, and then passes through the sampling pump to control the flow rate of the extracted gas through the flowmeter (the flow rate of the flowmeter is generally controlled at 0.3~0.5L/Min.), Finally, the instrument is tested (the working environment of the instrument needs to be used in the working condition of -20 ° ~ 60 °).

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. Sampling air pump about 1 year service life

 

Features

1. Detector detection principle: according to the demand range customization, and can provide customized products according to user needs, without tools to achieve sensor exchange, off-line 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. Dust filter, filter dust, when there is water, stored with peristaltic pump for discharge
6. Sampling pump, the longest sampling distance can reach 100 meters, it is recommended to be within 20 meters
7. Flow meter, control the gas flow rate, avoid the gas flow too fast to wash the sensor.

Pipe Description

There are 4 pipe connections:
One sampling air inlet;
2 water outlets, with a throttle valve on the water outlet, which is usually tightened and normally closed. Check regularly. If there is water in the water outlet pipeline, water can be discharged through the valve;
1 air outlet;
