Piezoelectric force sensor, also known as piezoelectric ring force transducer, for precise measurement of tensile and compressive forces in highest resolution.This piezoelectric (PE) force sensor of the 90x1 series measures forces in the z-direction. The ring force transducer contains a quartz sensor element which measures the force directly transferred through the cover and base of the tightly welded steel case. When subjected to a mechanical load, quartz produces an electric charge that is proportional to that load. An outstanding property of quartz is the very low threshold and, thus, a high sensor sensitivity that remains extremely linear over the entire measuring range. Thus the behaviour in a certain measuring range is practically identical for all PE sensors, independent of their size.
