Principle and application of dust concentration sensor

2019-06-19 Source: admin

Dust concentration sensor The fine electrostatic measurement method is used to monitor the dust content on-line in real time, measure the electrostatic charge carried by the dust in the pipeline, and output the standard current related to the dust concentration in the conveying pipeline through the well-designed calculation circuit, Because of the collision and friction between dust particles and dust particles, between dust particles and inner wall of pipeline, between dust particles and filter element, and between dust particles and flue gas, dust particles will carry electrostatic charge. The amount of electrostatic charge is directly related to the dust content in gas-solid two-phase fluid in the pipeline. The arithmetic mean value of charge amount and the root mean square value of disturbance momentum all reflect the dust content in the pipeline The bag leak detector of blast furnace gas dust collector is equipped with high precision, high stability and high reliability inspection and calculation equipment. All equipment are strictly selected. The dust concentration sensor meets the requirements of high, low temperature and oscillation inspection, two-wire system (4-20mA) standard output method, built-in signal blocking processor and perfect maintenance circuit. The output can be directly connected with PLC and DCS, so it is convenient to use, It is safe and reliable.
