More Precision eddyNCDT // Inductive sensors based on eddy currents

■ Measuring principle & fields of application alternating field Sensor with coil Eddy currents 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 magnetic field, eddy currents are...
