We have been measuring speed since 1925

What our speed sensors are used for

Our speed sensors are used for non-contact measurement of the rotational speed of scanning objects, such as thoothed wheels, perforated discs, pulse bands, objects with holes, openings or grooves. The measured value is typically specified as a frequency, e.g. in Hz or rpm.

Common measurement methods for this are:

  • Hall effect
  • Inductive-magnetic principle
  • Magnetoresistive principle or 
  • Eddy current principle

Each measuring method has advantages and disadvantages. The application is decisive for selecting the right technology. Depending on the measuring method, different measuring ranges from 0 to 30 kHz are possible, including standstill detection and detection of the direction of rotation.
