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


  • High stiffness
  • High accuracy (±0.05 % /F.S: frequency output)
  • High rotation speed : up to 22,000 r/min (standard),up to 25,000 r/min (option)
  • Long operating life: Non-contact signal transmission from the rotating section. Causing no wearing of parts and easy maintenance.
  • Slim flange type: Space-saving design
  • Accredited Calibration Laboratory by JCSS (Japan Calibration Service System)
