High-stiffness Torque Detector

TQ-2000 Series

 

TQ-2000 series
High-stiffness torque detector

 

 

TQ-2000 series is the high-stiffness and high-response detector for measuring the torque variation of an engine or a power train applied to the shaft.

 

Because of a very high torsional stiffness, fluctuating torque is accurately measured. As the detector is flange type without bearing, it can be connected to a rotating shaft directly. The slim and space-saving design enables easy mounting.

 

The TQ-2000 series is suitable for the torque test of an EV/HEV drive motor etc. that needs high speed rotation measurement.
