Mechanical power transmission through rotating machine parts often requires extensive investigations of machine parts that transmit or generate power. Furthermore, continuous monitoring is often required. This, in turn, makes it necessary to have transducers to sense the physical quantities torque and speed of rotation.
The torque transducers type T30FNA from HBM which are without sliprings, provide torque sensing as well as speed measurement. The torque transducers are suitable to determine static as well as dynamic torque in stationary and rotating shafts. Speed of rotation can be determined as well as the sense of rotation. The multiplication of both factors gives the shaft power. Torque transducers are available for nominal torque ratings from 50 Nm up to 10 kNm. The maximum speed rating is 3000 min-1.
A frequency modulation system with non-contacting, inductive transfer of the signal and the excitation voltage provides a system for the sensing of static and dynamic torque which is free from wear and maintenance. For every nominal torque HBM offer models for lower speed rating as well as for higher speed rating.
