Three-channel radio-frequency sensors with one sensitive element for invariant measurements


An algorithm for converting the primary data of a radio-frequency sensor, containing a sensitive element in the form of a distributed long line, excited at three resonance frequencies, is developed in connection with the problem of the invariant measurement of the position of the interface of a double-layer medium. The output characteristics of this algorithm for simple structures of the sensitive element are investigated.Its configuration to ensure uniqueness of the measurement and uniform sensitivity over the whole range of variation of the interface is synthesized.
