Eddy Current Sensors

Embedded Coil Technology (ECT) allows the limitations normally caused by the material and design to be exceeded. This fact makes the sensors unique. Technology for the production of coils in sintered inorganic carrier material has only been applied to customised applications. However, standard ECT eddy current sensors are now available from Micro-Epsilon. Eddy current sensors with Embedded Coil Technology differ from traditional sensors that use a wound coil. The sensor itself is embedded in an inorganic carrier material. Electronic components can be positioned on the carrier material. This technology has been developed for customised applications, which have high requirements in terms of temperature and long-term stability, as well as excellent repeatability. As this technology has been tested in OEM applications for several years, it can now be applied to standard eddy current sensors. ECT-sensors are suitable for extremely harsh environments. At temperatures up to 180°C, these sensors are permanently applied. The version with an integrated high temperature cable can also be used in temperatures up to 350°C. The new sensors are available with the new high performance eddyNCDT DT3300 controller.
