HBM Test and Measurement (HBM) has introduced its T21WN torque transducer. Based on strain-gauge technology, the T21WN uses contactless energy and measurement signal transmission to take measurements. The torque transducer enables the static and dynamic measurement of torque, rotational speed and angle of rotation to be performed on non-rotating as well as rotating components. HBM says that laboratory, test shop and testing applications will benefit, as well as performing production and process monitoring, and quality assurance.
Apart from the torque output signal of ±10 V at nominal (rated) torque, the transducer also provides a standard frequency output signal of 10 kHz ±5 kHz.
The T21WN torque transducer is available with nominal (rated) torques ranging between 0.1 and 200 Nm, while the maximum permissible rotational speed of the torque measuring system is up to 20,000 rpm, depending on the measurement range. An integrated rotational speed/angle of rotation measuring system with 360 pulses per revolution completes the transducer and can be used up to the specified maximum nominal (rated) rotational speed without restrictions.
HBM’s new torque transducer is supplied with a direct voltage of 24 V that is common in test benches. The T21WN is suitable for use in substantially more dynamic applications than the preceding model, the T20WN, thanks to its measurement bandwidth of 1 kHz. In addition, users benefit from a significantly broader range of functions than with
the preceding model – at the same price.
