Position sensing solution utilises magnetostriction

16 June 2015

MTS Sensors has expanded its EC-Series absolute position sensing family, based on its Temposonics magnetostrictive technology.

The new EC-Series models are designed to offer a higher degree of integration – with a choice of serial interface standards supported, plus built-in active signal conditioning functionality. Supplementing the original devices, which have direct signal outputs (both analogue and start-stop), the new versions have interconnects incorporated into the sensor housing that are compliant with either CANopen or synchronous serial interface (SSI) communication protocols. This results in enhanced system flexibility and added convenience. Depending on the cable length involved, the SSI and CANopen interfaces can handle data rates reaching 400kbits/sec and 1000kbits/sec respectively.
Specified for stroke lengths of between 50mm and 2500mm, both of the CANopen and SSI EC-Series devices exhibit less than ±0.005% full scale (FS) deviation in their repeatability and less than ±0.02% FS deviation in their linearity. The sensors have an operational temperature range of between -20°C and +70°C. Furthermore, they can withstand 90% relative humidity and are IP30 rated.
