The Liquiphant vibration probe analyses the change in frequency which is produced by a liquid on the sensor. The symmetrical fork paddles start vibrating piezoelectrically at their resonance frequency.
The application of a voltage makes the piezo expand and the metal membrane is bent due to the rigidity of the ceramic disc. The main characteristic of the bimorph drive is its mechanical insensitivity.
