Abstract

A method and an apparatus for monitoring at least one media-specific property of a medium in automation technology with a measuring probe, wherein the at least one media-specific property is ascertained in a conductive operating mode and in a capacitive operating mode of the measuring probe. The conductive operating mode and the capacitive operating mode are operated alternately, wherein based on the measured values, which are ascertained in at least one of the two operating modes, it is checked, whether the at least one media-specific property to be monitored lies within a predetermined tolerance band, and wherein a report and/or a switching signal is generated, when the at least one media-specific property to be monitored lies outside of the predetermined tolerance band.
