Eddy current sensors with embedded coil technology are significantly different from conventional sensors that use wound coil cores. The coil core is embedded into an inorganic carrier material. Micro-Epsilon developed this technology specifically for customised applications. Their innovative set up means that the sensors offer extremely high temperature and long-term stability, as well as excellent reproducibility. This technology has been tried and tested over many years in OEM applications and is now used for standard eddy current sensors. ECT sensors are suitable for extremely harsh environments. The sensors can be used for continuous operation at temperatures up to 180°C, and even as high as 350°C when using an integrated high temperature cable. These new sensors are available for use with the powerful eddyNCDT DT3300 controller.
