  • Page 15: Design

    4 Design Design The filter monitoring device PFM 13 consists of an in-situ probe with probe head and probe rod. The probe rod is surrounded by a guide bushing and an insulator. Thus it is electrically isolated from the housing. In the probe head the evaluation electronics are located.

  • Page 16: Connection Assignment

    4 Design Connection assignment The electrical connections of the PFM 13 are located in the probe head. The terminals at the signal module are performed as cage clamps. They serve as analogue output (4…20 mA) for output of the qualitative dust value [%] as well as for power supply (passive 2-wire transmitter).
