Tribo electric filter monitors measure the charge exchange between the probe and the streaming as well as the bouncing dust particles. These devices are suitable for monitoring baghouse-, envelope- and cartridge filters and centrifugal separators (cyclones).
There are more than 10,000 pcs of Dr. Födisch AG filter monitor devices operating worldwide such as food processing or cement industries, metal- and woodworking and chemical industries.
Different models of PFM filter monitors include:
PFM 20 C Qualitative triboelectric in-situ dust measurement for process and emissions monitoring
PFM 20 D Continuous, tribo-electric monitoring of dust concentration in exhaust gas
PFM 20 F Continuous, tribo-electric in-situ measurement for qualitative monitoring of exhaust gas PFM 20 m Mobile system for checking filter systems based on the tribo-electric measuring principle
