Embedded coil technology radically improves temperature stability and miniaturisation of displacement sensors

Micro-Epsilon’s new Embedded Coil Technology (ECT) represents a technological breakthrough in eddy current sensor design and manufacture, enabling the previous limitations of using eddy current sensors to be overcome. Due to its ultra-compact design and by using new inorganic materials in its construction, the new eddyNCDT ECT sensors provide almost unlimited scope in terms of the external design and geometrical shape of the sensor. This means the sensors can be adapted to suit virtually any application requirements.

EddyNCDT ECT sensors offer extreme mechanical robustness, resulting in longer service intervals and higher temperature stability. In addition, the complete circuit electronics can now be integrated into the sensor itself, providing an even more compact measurement solution for OEMs and machine builders. The sensors are also suitable for harsh operating environments, including high vibration, impact shocks and high operating temperatures as high as 350 deg C.

Sensors have been produced with extremely low thermal drift and with temperature errors of less than 20ppm/K (parts per million per degree Kelvin).
