Dust bag Leakage Detector
Overview:
The Dust Detector adopts the world's advanced charge induction measurement principle.The unique circuit design, the application of new devices, the new sealing technology of the measuring electrode, the high technology of spray insulation, and the stable high magnification of the very weak charge signal ensure the continuous online measurement of the dust concentration.
Working principle:
When the charged dust particles pass through the measuring electrode, the measuring electrode induces positive and negative charges, and the charge forms a current signal during the transfer movement; the size of the alternating current signal is proportional to the mass content of the dust. By further amplifying and processing the electrical signal, the dust concentration (mg/m3) can be accurately measured.
Features:
1.The dust concentration is measured by the principle of charge induction, the measurement accuracy is high.
2.Integrated structure, long current signal transmission distance, strong anti-interference ability.
3.The measuring electrode is sprayed with imported protective material, which improves the ability of high temperature resistance, corrosion resistance and anti-adhesion, reduces cleaning and maintenance, and extends the service life. Improve product quality.
4.The main body of the sensor adopts a special design, and the air-tight connection piece strictly prevents the measured gas from leaking and the measuring electrode is impacted and squeezed out due to pressure, which guarantees the safety of the transmitter and the staff.
5.DC24V non-polar power supply, using industrial two-wire power supply,low-power operation, improve the safety of this product.
6.The internal MCU has the functions of self-adaptation, automatic reference, and self-calibration, which can automatically adjust to the current working conditions at the initial stage of equipment installation; and automatically calibrate the equipment status at zero hour every day to prevent drift.
