1-Component Reaction Torque Link Kistler 9275 (±200Nm)

Quartz torque dynamometer for measuring a torque acting around the sensor axis. The compact dynamometer possesses high rigidity and therefore a high natural frequency, enabling the smallest dynamic changes to be measured in large basic torques.

Description

The dynamometer consists of a torque sensor which is fitted under high preload between a base plate and a top plate. The sensor contains a set of shear sensitive quartz disks. The arrangement of the disks is realised in a way to yield an electric charge which is proportional to the torque Mz acting around the axis of the dynamometer. The charge is led via an electrode to the TNC connector

Application Examples

• Testing torque wrenches
• Testing springs (torsion)
• Measurements on small thrust bearings, friction clutches etc.
• Measuring starting torques on fractional horsepower and stepping motors
• Ergonomic measurements

Mounting

The base plate has a ground underface and eight holes, enabling it to be fitted straight onto a rigid, face-ground surface. However, the dynamometer can also be fixed by means of claws. For clamping-on the force introducing parts, 12 threaded holes are arranged in the top plate. The supporting surfaces of the force introducing parts must also be ground or machined to equivalent standard.

Electronics

Besides the dynamometer a torque measuring system includes a charge amplifier, which converts the charge signal from the dynamometer into an output voltage. Full-range signal from a Kistler charge amplifier is 10 V.
