High-accuracy ATEX-certified magnetostrictive position sensor

April 20, 2015 // By Graham Prophet
MTS Sensors has designed a robust, high performance magnetostrictive position sensor, using its Temposonics technology. The ET sensor is suited to applications with high temperature environments. It can deliver up to 0.005mm resolution when used in combination with a suitable controller.

Industrial facilities dedicated to pressboard production or the processing of steel/iron need instrumentation that provides maximum safety and reliability, regardless of difficult working conditions. The new ET product offering extends the supported temperature range of the MTS E-Series, with the ability to precisely determine exact positions even at 105°C temperature levels. This small rod sensor can be integrated directly into a cylinder, with rod length options covering 50 mm to 3000 mm. It exhibits linearity deviation of less than 0.02% (full scale).

ET sensors have liquid ingress protection in accordance with IP68. Furthermore, ATEX certification for hazardous areas is available. These devices are equipped with a start/stop interface. "The ET sensor is designed to be reliable and operationally effective in industry sectors where elevated temperatures are a major concern,” said Robert Luong, MTS Sensors’ Industrial Technical Marketing Manager. “The magnetostrictive technology it uses provides a wear-free sensing mechanism that has significant value in heavy industrial settings.”

The proprietary Temposonics magnetostrictive sensing technology is a non-contact method for accurately measuring position, which permits its implementation into the most demanding of application environments. Sensors based on this technology are highly resilient to shock, vibrations and extreme temperatures.
