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.
TQ-2000 series is used with the TQ-5200 High-response torque converter
