Anaheim, CA — MTS Systems Corp. announced today at the Rockwell
Automation Fair a performance enhancement to its Temposonics® non-contact
position sensors. Based on the magnetostrictive principle,
the sensor measures absolute, linear position at the load.
While this approach has many
advantages, the measurement is time-based and the update rate is therefore
reliant on the overall stroke length. To overcome these limitations and extend
the sensor's use into applications that demand high-speed performance for
motion control, Product Manager John Balding explained that engineers have
added a predictive sensing algorithm to the sensor that provides updates every
100 µsec.
The controller is available for protocols
such as SSI (synchronous serial interface), which is a high-speed, point-to-point
interface for absolute encoders. It can read absolute position data at a 10 kHz
update frequency synchronized with an internal clock.
An outstanding resolution down to 1 micron
enables movement at very low speeds of 0.5 mm/sec. Sampling rates up to 10 kHz
are assured to track fast movement and cycle times. With a linearity of
Temposonics sensors enable simultaneous and
continuous position measurement of up to 30 different points on an axis and are
available in lengths up to 65 ft.
