1-Component Reaction Torque Link Kistler 9277A25 (±25Nm)

Quartz torque dynamometer for measuring a torque acting around the sensor axis. The compact dynamometer possesses an especially high sensitivity. The very lightweight top plate supporting the measuring object guarantees a high natural frequency, enabling torques to be measured on small high-speed
motors.

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

• Adjusting torques of pneumatic screw-drivers
• Testing of screw connections
• Calibrating of manual torque wrenches
• Testing of torsion of springs
• Measurements of friction clutches
• Measuring of starting torques, variations in synchronization and torsional vibrations of fractional horsepower and stepping motors

Mounting

The base plate has a ground underface and six 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, 6 threaded holes are arranged in a circle 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.
