Model PFM 92 C - Filter Controller
From Filter Monitoring
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.
