Non-contact eddy current sensors of the series eddyNCDT (eddy current Non-Contact Displacement Transducer) measure wear-free positions, displacements or distances. Eddy current sensors are mainly used for highly accurate measurements being effected in industrial ambient conditions. As the high-frequency lines of flux which are generated by the coil penetrate non-metallic material, measurements can be effected even under difficult ambient conditions (e.g. fouling, pressure or oil). Furthermore, this special feature allows the measurement of plastic-coated metals e.g. the measurement of coat thickness. OEM-solutions for customerised integration are possible upon request.
