T12 digital torque transducer

T12 digital torque transducer

HBM's new T12 digital torque transducer claims excellent dynamic measuring capability, high accuracy and secure digital data transmission and processing.

To benefit from the transducer's full capabilities it is vital that high performance mountings are used, such as HBM's own BSD MODULFLEX couplings. The MODULFLEX couplings do not degrade the T12 torque transducer's low measurement uncertainty (0.03 percent accuracy) when used within the design specifications. The couplings' minimal play also ensures the correct application of torque.

The couplings are reportedly maintenance and wear free, corrosion resistant and compact and are well matched to the T12 design.

MODULFLEX couplings have been designed to work with the T12 digital torque transducer without modification. When combined, the T12 and MODULFLEX couplings can be used horizontally or vertically and allow the use of high endurance components to ensure high reliability.

Purchasing and administration costs are reduced because both the coupling and transducer can be single sourced from HBM. The products are aimed at applications that include highly dynamic measurements on test stands used to develop systems such as power transmissions.

Currently, the T12 is available in four measuring ranges, with maximum capacities of +500Nm, +1kNm, +2kNm, and +3kNm.

By using “Trend Analysis” data can be examined in real time allowing structural weaknesses to be forecast at an early stage before any cracks develop. If material weakness is forecast then additional strain gages can be fitted to enhance, for example, the evaluation and cause of the weakness.

Catman Enterprise software used with “Trend Analysis” enables evaluation criteria can be defined and limit values set for data analysis during fatigue tests.
