Description

The product family of level probes Leveltec of the types Standard S, R, P, HAT, VAS is used for level monitoring and for dry run protection with non conductive media. The capacitive measuring method allows a wide application range also with changing media. An electromagnetic wave penetrates the media and depending on the dielectric constant ε the propagation time of the electromagnetic wave is influenced. Crusts, foam and condensate are not detected.

The output signal can be connected directly to a SPS or PLS for processing. The adaption to the process with respect of hygienic aspects is asured by a proper selection of the welding parts and front flat assembly to the process. The adoption of sockets for vibrating forks is possible. Due to the resistance against cleaning temperatures sterilisations and CIP cleaning cycles are executable. For highly oxidizing media, e.g. H₂O₂ as cleaning detergent, the application of Leveltec R is recommended. 

Independently of the conductivity of the media the controllable Leveltec P is especially well suited for level detection in pipes and vessels. The specialness is the alignment (optional) of the switching level of the output signal to the additional control input, which is controlled by the SPS / PLS. The switching status of the output signal is indicated by a LED (constantly, dichromatic) on the connecting circuit board.
