Pressure and shear sensitive quartz disks are integrated under high preload between a hollow preload screw and a nut designed as the sensor case. Because of the extremely high rigidity of the sensor elements, the components F z and M z are measured practically without change of stroke or angle. The force and torque-proportional charge signal is picked up by electrodes and fed via a shielded cable to the charge amplifier. The latter converts the charge signals into proportional output voltages, which can be recorded and evaluated.

Flanges with tapped holes in the top and bottom sides of the sensor allow simple mounting on a shaft or adapter flange. Centering seats on both sides permit a very accurate coaxial fitting and a centric bore allows shafts to be inserted.
