Application and function

The mobile filter controller PFM 92 K is a perfect device in order to determine effectively damages at filtering precipitators (e.g. defective filter bags, inactive membrane valves, insufficient filter element fixings, not tightly-closing poppet valves…). The filter diagnosis unit PFM 92 K serves the qualitative monitoring of dusty emissions. In particular it is often used for the quick 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 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. The measuring values resp. the filter diagram can be seen and evaluated immediately via the integrated electronic recorder
