Based on the principle of micro-charge and microwave measurement, the circuit adopts AC dynamic signal filtering to filter out the DC baseline caused by static ash accumulation on the tube wall and electrode, and only captures the alternating charge caused by the flow of powder; long-term hanging on the tube wall and slight agglomeration will not trigger a false alarm and there is no need to purge frequently.
Suitable for stable monitoring of pulverized coal, cement, fly ash, lime powder, lithium electric graphite/lithium iron phosphate, plastic granules, grain flour, carbon black, and metal mineral powder
