MTS Systems Corporation (NASDAQ: MTSC) is a global supplier of position sensors for a wide variety of markets and applications. A pioneer in precision force and motion control, MTS leverages more than 40 years of industry experience to provide products that determine the mechanical behavior of materials, products and structures.
MTS Sensors (a Division of MTS Systems Corp.) has manufacturing facilities located in America, Europe, and Asia that deliver leading-edge position and liquid-level sensors, and is the world's leading supplier of magnetostrictive-based sensor products. The Sensors Division was created by MTS Systems when it acquired Temposonics, Inc. in 1984. Temposonics remains the key technology brand for MTS Sensors and reflects an ongoing commitment to high-precision position and liquid level measurement technology development.
Temposonics Technology is the manner in which MTS applies the principles of magnetostriction to create a reliable position measurement system for use in industrial environments. Inside the sensor 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, and the other field is generated from a current pulse which is applied to the waveguide. The interaction between these two magnetic fields produces a strain pulse which travels at sonic speed along the sensor 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 application of the current pulse and the arrival of the strain pulse. As a result, MTS is able to create a reliable position measurement system that is capable of providing an accurate and repeatable measurement.
