Filling level sensor to the limit value detection of electrically or capacitively conductive liquids

摘要

The present invention relates to a filling level transmitter for the limiting value registration of electrically or capacitively conductive liquids, having at least one capacitor for forming the registration means, the registration means being arranged within a protective tube and the registration means having a vertically aligned registration surface and communicating with at least one radio-frequency generator via a bus line which is designed as at least a two-wire line which is designed, at least in the protective tube, as a rigid line for the accommodation of the registration means at variable heights.
