Product Details

1、 Product Description
The electrostatic dust detector (bag leak detector/pipeline dust detector) measures the electrostatic charge induction of dust particles passing through a fixed probe. Dust particles and probes induce static charges, which are amplified by the probe and transmitted to the monitoring and control system. The size of static charge is proportional to the flow rate of dust particles. The high-tech electronic circuit of this system converts this part of the charge into a control signal output, activates the dust over limit emission alarm, and is used to continuously record the total amount or concentration of dust particles. The device provides the current new AC coupling technology. This is a modern and stable monitoring technology, particularly suitable for continuous emission recording and data accumulation.

2、 Scope of application

Electrostatic dust detectors are widely used in various industrial applications, including steelmaking, power generation, petroleum, chemical, pharmaceutical, building materials processing, coal mining and mining, cement manufacturing and packaging industries. Typical applications include detecting damaged filter bags in bag filters, recovering powdered materials, monitoring the total amount of product transportation, or monitoring the concentration of smoke and dust emissions from boilers of various sizes and fuels.
