Abstract
A movement sensor (40) for a process device has a sensor tip (42); means (41) for transmitting the vibrations from the sensor tip to a transducer means (43), the transducer means electrically detecting the resulting vibrations as movement occurs and producing an output signal. Means (70) can be provided for filtering the output signal below and above respective predetermined frequencies and producing a movement detection signal when the output signal lies between the predetermined frequencies.
