The 3-component force sensor is mounted under preload between two mounting flanges. The quartz force link can therefore measure compression and tensile forces.
The force measurement of the sensor is based on the piezoelectric principle. The application of a force results in the quartz washers in the sensor (one for each of the force components to be measured) yielding a charge proportional to the force. This is picked off by built-in electrodes and transferred to the corresponding connector.
The contact faces of the sensor are covered with ceramic discs to facilitate ground-isolated mounting of the sensor. The straightforward and vibration-resistant design of the sensor produces a very rigid structure. The resulting high natural frequency makes highly dynamic force measurements possible over a large frequency range.
