KFS/KFA/KFX - pojemnościowe czujniki poziomu


Image

Systemy pomiaru poziomu pojemności (KFS/KFA/KFX) działają w oparciu o metodę 3-elektrodową. Zgodnie z tą zasadą, zbiornik lub dodatkowa elektroda pełnią funkcję elektrody przeciwnej do elektrod sondy.



Charakterystyka

The capacitive level measurement systems (KFS/KFA/KFX) operate according to the three-electrode principle. With this principle the container or an additional electrode serve as a counter-electrode to the probe electrodes. For this reason it is necessary with this system that the container is of a conductive material or a "substitute electrode" is fixed to the container wall, e.g. copper foil. These systems are available with probes for analogue filling level measurement or for detection up to 4 measuring points. The position of the switching points and the analogue measuring area is custom made within the possible effective range and therefore it can be determined for optimized matching of each application.

Zastosowania

Level measurements of bulk material, liquids or pastes are possible with a dielectric constant as of εr 1,1.
