About This Product
■Torque sensor T40B
World standard torque measurement with excellent cost performance Magnetic rotation speed measurement is also available as an option.
■T40B: Standard torque that allows simultaneous measurement of rotational speed and angle
Torque sensor T40B is a world standard wireless torque flange that combines high accuracy, repeatability, and robustness. It is suitable for both static and dynamic measurements, and has high stability against temperature changes, with nonlinearity including hysteresis of 0.03%. If you choose the magnetic rotation speed measurement system or reference pulse option, you can simultaneously measure the rotation angle required for EV testing, achieving highly accurate power analysis.
An Internet connectivity module is also available to easily integrate the T40B into various next generation networks such as EtherCAT and PROFINET.
■Even faster rotation
The rotation speed of T40B has been further expanded. Measurements up to 23,000rpm (1kNm) or 18,000rpm (2 and 3kNm) are possible. This also supports the speed resistance requirements of electric drive systems.
