Description
TQ-3507 Series Torque Detector
tq3507_eFeatures
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.
Application example in RC-S
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.
Calibration with a high-precision torque reference device
It has passed the load durability test of 10 million times or more continuously with the rated torque of ± 100%. In addition, it is a highly durable detector that ensures sufficient safety for material proof stress.
Limit torque : 10 kN · m（200 % of rated torque）
Breakdown torque : 20 kN · m（400 % of rated torque）
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.
