The dust monitor DYNAguard GM is used to detect malfunctions in dedusting plants, which can be caused by damaged or incorrectly installed filtration media.
The used electrostatic measurement principle is based on a modified triboelectric principle. Not only particles which hit the measuring rod are detected, but also those passing by.
Deposits on the sensor rod do not influence the measurement, since only moving particles are detected.
Because signal damping is adjustable, short peaks do not cause a false alarm. The signal gain can be adjusted easily according to the individual process.
With the analog output version (in connection with a PLC) it is possible to monitor more than one threshold and to plan filter maintenance by monitoring the cleaning cycles.
