MTS Temposonics® Position Sensors On The Job

Injection Molding Machines
Our sensing technology is routinely used on 3 axes of plastic injection molding machines: injector control, ejector control and mold closure. Superior ruggedness and reliability as well as a host of other applicable performance features, make Temposonics the smart choice for this application.

Hydraulic Cylinders
High-performance and durability make Temposonics position sensors the standard in the hydraulics industry. An innovative modular design allows you to easily replace the sensing element and electronics without breaking the cylinder's high-pressure seal. This feature significantly reduces maintenance cost and downtime.

Primary Woodworking
Temposonics sensors are designed and built to withstand the rigors of sawmill applications. So effective are Temposonics sensors in withstanding the high shock and vibration inherent in this rugged application, they have become the industry standard.

Presses
High performance Temposonics R Series sensors are required for this exacting application. The Temposonics line of sensors provides the high-frequency update rates and superior resolution (up to 2 microns) and linearity needed for effective press performance.

Magnetostriction - how it works.

In a Temposonics transducer, a torsional strain pulse is induced in a specially designed magnetostrictive waveguide by the momentary interaction of two magnetic fields. One field comes from a moving magnet, which passes along the outside of the transducer tube, the other field from a current pulse launched along a wire inside the waveguide.

The interaction between these two magnetic fields produces a strain pulse which travels as sonic speed along the waveguide, until the pulse is detected at the head of the transducer. The position of the moving magnet is precisely determined by measuring the elapsed time between the launching of the electronic pulse and the arrival of the strain pulse. As a result, accurate non-contact position sensing is achieved with absolutely no wear to any of the sensing elements.
