The reaction torque sensor is integrated under high preload between preload screw and nut. When a torque acts on a sensor, the shear stresses produced are transmitted to the crystals. The charge signal proportional to the force is picked up by an electrode and fed through a screened cable to a charge amplifier. The charge signal is converted by the charge amplifier to a proportional output voltage, which can be recorded and evaluated.

Flanges on the top and bottom sides of the reaction torque sensor allow simple and direct installation on a shaft or adapter flange. This allows very low, space-saving installation. Alternatively, a mounting flange (optional accessories) can be used or installation can take place using custom adapters. A two-sided centering facility allows very accurate coaxial fitting. A centric bore allows additional applications, e.g. for shaft bushing. A screw-on connector cover ferrule is provided with the included accessories to protect the cable connection at the side.
