Plug in dust detector in stockWorking principle

During the transportation of gas-solid two-phase fluids containing dust particles, the collision and friction between dust particles and dust particles, as well as between dust particles and the inner wall of pipelines, will cause the dust particles to carry charges and form an electrostatic field. When charged dust particles pass through the measuring electrode, positive and negative charges are induced by the measuring electrode, and the charges form a current signal during the transfer motion; The magnitude of this AC signal is directly proportional to the mass content of dust. By further amplifying and processing this electrical signal, the dust concentration (mg/m3) can be measured.

Performance characteristics:

1. By using communication coupling technology, the detection sensitivity of dust is high, the linearity is good, and dust contamination of the probe does not affect the measurement sensitivity. It is maintenance free and requires no cleaning.

2. Standard two-wire 4-20mA current output, strong anti-interference ability, easy long-distance signal transmission, no special requirements for signal transmission wires, linear relationship between output current and dust concentration, convenient for subsequent PLC data processing.

3. The installation and use are consistent with the two-wire pressure transmitter, and on-site engineering and technical personnel can use it correctly without any special training. The installation is convenient and the operation is reliable.

4. The integrated transmitter output 4-20mA current in the junction box is electrically isolated from the dust sensing probe to achieve safe signal transmission.

Insertable Dust Monitor is an instrument used to detect the concentration of dust inside pipelines or equipment. It monitors dust emissions by inserting sensors into pipelines or equipment to measure dust concentration. The working mechanism and application areas of the plug-in dust detector are as follows:
