■ General
The WGS-A dust switch is used for monitoring the dust concentration exceeding the standard when the bag of the bag type dust remover is damaged, and also for monitoring the dust concentration in all metal pipes. The minimum measurement range can reach 0. lmg/m In addition, depending on its rapidity and reliability, the product can also be installed in the bag filter to replace the differential pressure transmitter for monitoring the operation of the filter.
WGS-A is a standard alarm type, which can be explosion-proof type LTS AEX, high temperature resistant type WGS AHT and other models. WGS-A adopts stable and reliable electrostatic principle. When solid particles flow through the probe rod or hit the probe rod, an electromotive force will be generated. This electromotive force is converted into a measurement signal. When the measurement signal exceeds the set value, the system will give an alarm.
