PFM 92 Compact

Kompakti pölymittari suodattimien valvontaan  

Application and function
The filter controller PFM 92 C serves the qualitative monitoring of dusty emissions. In particular it is often used for the registration of the clean gas dust content behind de-dusting facilities. The measuring principle is based on the use of the triboelectric effect (charge transfer at colliding or passing of particles on leading surfaces).
The filter controller consists of an isolated probe which is installed in the clean gas channel. The complete electronic is integrated in the probe head. No additional control unit is required. The charge transferred by contact and triboelectric processes is derived as current, converted in the evaluation unit, amplified and provided as norm signal 4 ... 20 mA. Via a limit value detector the exceeding of the allowable emission limit value can be signalised optically or acoustically.
Due to the compact design the measuring device is especially suited for the construction of complex monitoring systems with several emission sources.
