MTS Systems Corp.Ãs Sensors Division has implemented a
third-generation testing unit for calibrating linear position sensors. The MTS
Universal Tester III is based on a precision-grade, belt-driven linear module with
an overall resolution of 79 nanometres. Additionally, the system allows
compensation for temperature and pressure variations, and performs all test
functions 20 per cent faster than previous generation testers, according to the
company. The new tester allows MTS to automatically “map” the linearity error
of each sensor and program a compensated output characteristic into each one.
