All Inclusive: Torque, Rotational Speed, Angle of Rotation. The T21WN torque transducer is ideal for measuring low torque as well as rotational speed or angle of rotation

T21WN Torque Transducer: Torque Measurement up to 200 Nm

The strain gauge technology-based T21WN uses non-contacting energy and measurement signal transmission to measure torque. The sensor is ideal for reliable measurement of relatively low static and dynamic torque on non-rotating as well as rotating components. The output signal at nominal (rated) torque is +/-10 V. The T21WN can be used, for example, in test benches for bearings as well as in material or haptic tests in medical engineering applications and research laboratories. Like its predecessor (T20WN) the T21WN can be easily and quickly integrated into the measurement chain using the robust VK20A junction box.

HBM accuracy class: 0.2
Nominal (rated) torque: 0.1 Nm to 200 Nm
Nominal (rated) rotational speed (rpm): up to 20,000
