Absolute sensors
The name “absolute sensor” is derived from the fact that the absolute value of the voltage induced in the test coil is measured. The signal of a defect or a change in the properties of the test specimen is superimposed on the signal when the test specimen is free of defects or when the coil is empty. The test signal is therefore influenced not only by defects, but also by the material properties of the test piece and the environmental conditions. If, for example, the sensor h
