Sensor assembly and method for contact-free determination of the effective torque in a shaft

摘要

The sensor arrangement has a transmitter coil (2) which is arranged on an E-shaped iron bar (6), and three receiver coils (3-5) that are arranged on an E-shaped iron bar (7). The receiver coil (4) is arranged slightly offset from transmitter coil. Two receiver coils (3,5) are arranged at preset intervals with respect to receiver coil (4). An independent claim is included for method for contactless determination of torque of shaft.
