Abstract: There is a testing device for testing a sensor. The testing device includes a rotating mechanism; a first rotating plate connected to the rotating mechanism so that the first rotating plate rotates around an orbital axis (Z1); a second plate rotatably attached to the first rotating plate at a rotating point, the second plate having a rotational axis (Z2) offset from the orbital axis (Z1) by a predetermined distance R; and a gripping mechanism attached to the second plate and configured to receive and fix the sensor relative to the second plate. The second plate follows a circular trajectory with constant attitude around the orbital axis (Z1).

Abstract: A method for electrically setting a gap for a piezoelectric pressure sensor. The method includes positioning a piezoelectric flex element on a tray; attaching a voltage source to the piezoelectric flex element of a piezoelectric pressure sensor; applying a voltage from the voltage source to the piezoelectric flex element; curing an adhesive between the piezoelectric flex element and the tray while the piezoelectric flex element is deflected by the voltage; and stopping the voltage from the voltage source to the piezoelectric flex element when the adhesive has been cured.
