How it Works

The transducer comprises a sensor element (shown in blue), a signal converter (at the right of the diagram) and a position magnet.

The signal converter applies an electrical pulse to the sensor element and simultaneously starts a timer.

The magnetic field generated around the sensing element by the electrical pulse interacts with the field of the position magnet and produces a mechanical pulse.

The mechanical pulse travels back down the sensing element where a sensor in the signal converter detects it and stops the timer.

As the speed of the mechanical pulse is constant, the time taken for the pulse to reach the sensor can be used to accurately measure the position of the magnet.

Typically the mechanical pulse travels at 2800m/s and the cycle process is repeated 1000 times per second.
