Tribo Electric Type
Description
Dry dust detector adopts the world's most advanced principle of charge induction measurement, independently developed and produced by our company.The series of products are widely used in steel, metallurgy, power generation, petroleum, chemical, cement, mining and other industries gas solid two-phase flow dust concentration online measurement.Typical application: the blast furnace gas bag dust removal, TRT power generation, dry method and wet method, electrostatic dust removal, carbon concentration on-line continuous monitoring pulverized coal boiler, instead of in the past by artificial old timing sampling analysis, found that dust emission concentration in time, avoid the loss of available dust, protect gas recycle production equipment, lower consumption, deeply user welcome!
During the transportation of gas-solid two-phase fluid containing dust particles, dust particles will be charged due to the collision and friction between dust particles and dust particles and the inner wall of the pipe.When charged dust particles pass through the special measuring electrode, the measuring electrode can induce positive and negative electric charges, and the electric charges can form pA current signals in the transfer movement.The size of the ac signal is proportional to the dust mass.The dust concentration (mg/m3) can be accurately measured by further amplifying and processing the electrical signal.
Features
•. Dust concentration is measured by charge induction principle with high measurement accuracy.
•. Integrated structure, long distance of current signal transmission, strong anti-interference ability.
•. The measuring electrode is protected by spraying or casing, which improves the ability of high temperature resistance, corrosion resistance and adhesion resistance, reduces cleaning and maintenance, prolongs service life and improves product quality.
•. The main part of the sensor adopts patent design, and the air-tight connector strictly prevents the gas leakage under test and the measuring electrode is impacted out due to pressure, which guarantees the safety of the circuit and the staff.
•. Non-polar two wire connection, low power consumption operation, improve the safety of the product and field use.
•. Adopt full metal shell, waterproof, dustproof and explosion-proof.
