Abstract (en)
[origin: DE102005062813A1] The arrangement has a control unit (19) to produce an electrical exciter signal and/or to process an electrical receive signal. A piezoelectric oscillating unit produces a mechanical oscillation based on the exciter signal and/or converts the oscillation into the receive signal. A temperature determining unit (17) determines a temperature of the oscillating unit and/or a temperature of a surrounding of the oscillating unit. The control unit produces a switch signal and/or a warning signal when achieving a threshold temperature or depending on the oscillating unit temperature. An independent claim is also included for a method of operating a vibration limit switch.
