Kistler Model 9277A5 Quartz Torque Dynamometer
Kistler Model 9277A5 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 torque to be measured on small high-speed motors.
The dynamometer consists of a torque sensor which is fitted under high preload between a base plate and top plate. 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
