T40B With Rotational Speed Measuring System and Reference Pulse


The market offers countless options for incremental rotational speed measurement systems. However, these systems are designed solely for measuring rotational speed. Combining rotational speed and torque measurement capabilities in a single measurement sensor imposes unique demands on the measurement of rotational speed:

  • The mechanical and application-specific features of the measurement sensor must not be impaired by the speed measuring system.
  • A high-resolution system that simultaneously allows large relative motion between the rotor and the stator is required.
  • The integrated rotational speed measuring system must not interfere with the transmission of the required nominal (rated) or limit torques.

Integrating the rotational speed measurement system with the transducer greatly facilitates handling. If necessary, the second shaft end is no longer required for a speed measuring system and is available for other tasks, such as an additional torque sensor.
