More Precision eddyNCDT // Inductive sensors based on eddy currents

Measuring principle & fields of application Electromagnetic alternating field Sensor with coil Eddy currents Distance Metal plate Measuring principle Among inductive displacement sensors, the eddy current principle occupies a unique position. Measuring via eddy current is based on the extraction of energy from an oscillating circuit. This energy is needed for the induction of eddy currents in electrically-conductive materials. Here, a coil is supplied with an alternating current, causing a magnetic field to form around the coil. If an electrically conducting object is placed in this...

Standard installation situation Each eddyNCDT sensor is factory-calibrated under standardized installation conditions. These installation conditions involve mounting, positioning of the nut and surrounding materials. Deviations installation situations may affect the linearity and accuracy. Field linearization or special tuning in the factory may counteract this effect. Standard target materials eddyNCDT sensors are factory-calibrated for the following materials: Ferromagnetic target: Steel (St37) DIN1.0037 Non-ferromagnetic target: Aluminum AICuMgPb3.1645 Customer-specific adjustment for...
