1 Temposonics Magnetostrictive Linear Position SensorsEP / EL AnalogData Sheet For standard applications Position measurement with more than one magnet Ideal for limited installation spaceI 2 ITemposonics EP / EL AnalogData SheetFig. 2: Typical application: Factory automationMEASURING TECHNOLOGYThe absolute, linear position Sensors provided by MTS Sensors rely on the company s proprietary Temposonics magnetostrictive techno-logy, which can determine position with a high level of precision and robustness. Each Temposonics position sensor consists of a ferromagnetic waveguide, a position magnet, a strain pulse converter and supporting electronics. The magnet, connected to the object in motion in the application, generates a magnetic field at its location on the waveguide.

2 A short current pulse is applied to the waveguide. This creates a momentary radial magnetic field and torsional strain on the waveguide. The momentary interaction of the magnetic fields releases a torsional strain pulse that propagates the length of the waveguide. When the ultrasonic wave reaches the end of the waveguide it is con-verted into an electrical signal. Since the speed of the ultrasonic wave in the waveguide is precisely known, the time required to receive the return signal can be converted into a linear position measurement with both high accuracy and 1: Time-of-flight based magnetostrictive position sensing principle4531 Measurement Cycle1 Current pulse generates magnetic fi eld2 Interaction with position magnet fi eld generates torsional strain pulse3 Torsional strain pulse propagates4 Strain pulse detected by converter5 Time-of-fl ight converted into positionSensing element (Waveguide)Position magnet (Magnetic fi eld)Torsional strain pulse converter2EP / EL SENSORR obust, non-contact and wear free, the Temposonics linear position Sensors provide the best durability and precise position measurement feedback in harsh industrial environments.

3 Measurement accuracy is tightly controlled by the quality of the waveguide manufactured exclusively by MTS compact Temposonics EP as well as the ultra low Temposonics EL are profile Sensors suitable for standard applications and in parti-cularly for applications with limited installation space. The evaluation electronics is accomodated in an aluminum sensor housing. Typical fields of applications are plastics industry, metal forming and wood-working as well as factory automation.
