PFM 20 C Dust sensor Dr. Födsch

PFM 20 C Continuous,  dust sensor, triboelectric monitoring of dust emissions

The PFM 20 C is a very sensitive analyzer for continuous measurement of dust emissions. The dust measurement meets the highest international and European standards.
This simple measurement is very suitable for emission measurement at waste incineration plants  and other combustion plants.

The PFM 20 C is used for continuous, qualitative monitoring of the dust content in flue gases at channels or
stacks without insulation. As a filter monitor, it is used for permanent control of dust separators. The device consists of a probe rod and a compact probe head. It is suitable for chimneys with as well as without insulation. Depending on the configuration, a Tri-Clamp connection or a flange DN 25 is used for the process connection.
The properties and numerous configurations of the PFM 20 C make diverse and demanding applications easily possible.

The  dust sensor is a Plug-And-Play device and easy to maintain.
The clamp connection also enables quick installation, and this assembly is also easy to disassemble for maintenance.

The robust design ensures a long lifespan > 10 – 15 years.
