Why piezoelectric force sensors beat strain gauge!

Piezoelectric force sensors have some outstanding characteristics which make them the first choice for multiple measurement challenges. While strain gauge force sensors need a certain level of physical deformation, piezoelectric sensors measure nearly deformation-free. The load on the piezoelectric crystal inside the sensor results in a charge proportional to the applied load.
In only 4 minutes Martin Stierli explains you a multitude of impressive facts about piezoelectric force sensors and where they offer you great advantages over strain gauge alternatives. Applications like aircraft landing gear testing or bird strike testing, impact testing in general, measuring microvibration of satellite reaction wheels, thrust measurements, force-limited vibration testing and many more profit heavily from the unique benefits of piezoelectric sensors.
