Rotary Motion logger sensor NUL-226

Rotary motion logger sensor


This sensor measures angles, rotations, rotation speeds or rotation acceleration. The sensor has a pulley connected to its shaft and the pulley rotation is measured. This sensor has four modes of operation: degrees, rev/s, rad/s, rad/s2.

  • Used for any science experiment which involves rotary motion including angular velocity, angular acceleration and revolutions per second such as in the fields of Mechanics, Physics, Biomechanics, etc.
  • The probe shaft is installed in a bearing and has a magnet at its end. A digital sensor based on The Hall Effect sensor, an analog circuit and a very sophisticated digital processor are located near the rotating magnet.
  • Includes a rotary motion revolving head piece attached directly to the sensor’s body by a durable rubber-coated wire.
  • The sensor is pre-calibrated at the factory.
  • Includes a reset to zero option for the measured angle.
  • Experiment duration: 1 second to 31 days.
