T40MS for High-Speed Torque Measurement up to 30,000 Rpm T40MS for High-Speed Torque Measurement up to 30,000 Rpm | HBM

T40MS Torque Flange: Small, Compact, and Short – Ideal for High Rotational Speed of up to 30,000 rpm

The T40MS torque transducer is a space and cost-saving solution for applications with a high rotational speed of up to 30,000 rpm. It is characterized by its very compact, short, and mass-optimized design and covers the available nominal torques with only one measuring body size. This significantly simplifies its handling in the application. The proven in use T40 electronics deliver the usual high precision, making the sensor, in combination with its other properties, ideally suited for tests in which high rotational speeds and robustness are required, such as fully electric drives, transmission test benches, as well as test benches for helicopter components and adjustable actuators, etc.

  • HBM accuracy class: 0.05
  • Rotational speed:  up to 30,000 rpm
  • Nominal (rated) torque: 200 Nm, 500 Nm, 1 kNm, and 2 kNm
