Measuring technology

For position measurement, the absolute, linear Temposonics® position sensors make use of the properties offered by the specially designed magnetostrictive waveguide. Inside the sensor a torsional strain pulse is induced in the waveguide by momentary interaction of two magnetic fields. One field is produced by a moving position magnet, which travels along the outside of the sensor rod, and the other field is generated by a current pulse applied to the waveguide. The interaction between these two magnetic fields produces a strain pulse, which is detected at the head of the sensor. The position of the moving magnet is determined precisely by measuring the time elapsed between the application of the current pulse and the arrival of the strain pulse. The result is a reliable position measurement system capable of ensuring accurate and repeatable measurement.
