Device for determining and / or monitoring at least one level of at least one medium in a container according to a travel time measurement method and / or a capacitive measurement method

摘要

The present invention relates to a device (1) for detecting and / or monitoring at least one filling level (F, FO, FU) of at least one medium (2, 3) in a container (4) according to a transit time measuring method and / or a capacitive measuring method at least one measuring probe (5), which device (1) comprises: a capacitive measuring circuit (8), a time domain reflectometer measuring circuit (7) and a control / evaluation unit (6). The invention results from the fact that a crossover is provided which directs the low-frequency measurement signal (SNF) and the high-frequency electromagnetic measurement signal (SHF) to the measurement probe (5) and which separates the high-frequency electromagnetic measurement signal (SHF) into the signal first signal path (17) of the time domain reflectometer measuring circuit (7) and the low-frequency measuring signal (SNF) in the second signal path (18) causes the capacitive measuring circuit (8).
