This easy to install piezoelectric reaction torque sensor is particularly suitable for measuring rapidly changing torques at non-rotating shafts. Its measuring range is ±1 Nm.

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.

This Kistler reaction torque sensor reliably detects even the slightest torques acting on the sensor axis in both rotary directions.
