Benefits of Magnetostriction
Temposonics linear-position
magnetostrictive position sensing principle developed by MTS.
Within the sensing element, a sonic-strain pulse is induced in a
specially designed magnetostrictive waveguide by the momentary
interaction of two magnetic fields. One field comes from a moveable
permanent magnet that passes along the outside of the sensor. The
other field comes from an "interrogation" current pulse applied along
the waveguide. The resulting strain pulse travels at sonic speed along
the waveguide and is detected at the head of the sensing element.
The position of the magnet is determined with high precision and speed
by accurately measuring the elapsed time between the application of
the interrogation pulse and the arrival of the resulting strain pulse with
a high-speed counter. The elapsed time measurement is directly pro-
portional to the position of the permanent magnet and is an absolute
value. Therefore, the sensor's output signal corresponds to absolute
position, instead of incremental, and never requires recalibration or re-
homing after a power loss. Absolute, non-contact sensing eliminates
wear, and guarantees the best durability and output repeatability.
