Magnetostriction: How it works

In a Temposonics position sensor, an electronic pulse called a current pulse (A.) is created in the head of the unit and sent speeding down the sensor tube.

Down the tube, a circular magnet having it's own magnetic field, (B.) indicates the position of the hydraulic cylinder. As the current pulse (A.) interacts with the magnetic field (B.) a strain pulse (C.) is produced and travels back along the sensor tube until it is detected at the head of the unit.

The position of the circular magnet is determined precisely by the time it takes between launching the electronic pulse and strain pulse to return. As a result, accurate position of the hydraulics unit can be found, with no wear to any of the sensing elements.

ACS Hydraulics is a proud distributor of MTS Temposonic sensors.
