During the transportation process of gas-solid two-phase fluid containing dust particles in the bag dust removal detector of the steel plant, the collision and friction between dust particles and dust particles, as well as between dust particles and the inner wall of the pipeline, 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 accurately measured.
Bag filter dust detector for steel plantUsing the principle of charge induction to measure dust concentration, the measurement accuracy is high.Integrated structure, long distance for current signal transmission, strong resistance.The measuring electrodes are made of imported protective materials, which improve their ability to withstand high temperatures, corrosion, and adhesion, reduce cleaning and maintenance, and extend their service life. Improved product quality.
Bag filter dust detector for steel plantThe main body of the sensor adopts independent research and development design, and the airtight connection piece strictly prevents the leakage of the measured gas and the outward impact and extrusion of the measuring electrode due to pressure, ensuring the safety of the transmitter and staff.Equipped with automatic zero adjustment function, it is convenient to check the zero point.DC24V power supply, low power consumption, will not affect normal production.Adopting intelligent circuit design, with three alarm outputs, the alarm value can be set arbitrarily.
