Product Details

Integrated dust switchWidely 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 detection of bag damage of bag type dust remover, online monitoring of dust concentration of various dust removers, materials, boiler flue gas, and gas pipeline dust concentration in iron making gas dedusting process, or monitoring of powder material recovery and total product transportation. Especially for online monitoring of dust concentration in TRT power generation gas pipelines, it plays an important role in real-time monitoring whether the dust in the gas pipelines meets the requirements of TRT power generation, thereby ensuring that the fans are not worn out. This device has high sensitivity, accurate and timely signals, and the sensor can directly output 4-20mA (or RS485 communication, Modbus RTU protocol), reducing signal interference during transmission, making it a practical dust online monitoring device for various industrial enterprises.
