Flange type High-stiffness Torque Detector TQ-3507

Capturing minute fluctuations accurately

Flange type High-stiffness Torque Detector

The improvement of energy efficiency has been required in future generation vehicles. The TQ-3507 Torque Detector developed for the measurement of torque capacity 5 kNm accurately captures minute torque fluctuations. It helps to grasp the energy loss precisely and improve energy efficiency of your system.


1. Outstanding mechanical characteristics 

 Achieves high stiffness

Torsional stiffness : 13,000 kN · m/rad

The torsional resonance frequency (detector itself) is approx. 3,500Hz.
Increased stiffness while maintaining accuracy. The high stiffness enables to accurately reproduce the driving state of the actual vehicle, and capture even minute torque fluctuations.

 Light weight

Reviewed the structure and achieved a weight reduction of about 3 kg compared to the existing model.

Calibration with a high-precision torque reference device

2. High accuracy

The non-linearity including hysteresis is most basic characteristics required for highly accurate torque measurement. ±0.02 %F.S. is available with the optional high accuracy.

Standard      Option
±0.05 %F.S. ⇒  ±0.02 %F.S.

Durability testing with continuous load testing system

Example of system configuration

Bench system for evaluation of EV drive unit

Accurately measures the transient torque when driving on a snowy road or on a wavy road that is reproduced on a bench.

Torque measurement system

Supports general-purpose digital communication to accurately transmit measured torque.
