RPM Measurement


Rotational-speed-dependent data, such as flowrate from variable pumps, are determined ideally in combination with the pressure and volume flow measurement of a hydraulic drive.

Contactless speed measurement (opto-electronic principle) can be done quickly and easily.

The rotational speed is measured e.g. on a drive shaft and displayed on the handheld device. Installation or adjustment are not necessary.


  • Also for contactless measurement of rotational speed
  • Measures up to 10,000 RPM
  • With 3-meter fixed cable
