Quartz Torque Dynamometer Kistler 9275
Kistler 9275 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.
The Kistler 9275 quartz torque dynamometer consists of a torque sensor, which is fitted under high preload between a base plate and a top plates. The sensor contains a set of shear sensitive quartz disks. The arrangement of the disks is realized 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.
Besides the Kistler 9275 quartz torque 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.
