Varimacndt Varimac eddy current sensor

 

Eddy current comparators operate on the principle that when a metal part is placed inside or near a test coil which is excited by an alternating current, the voltage output from the coil will be affected. This effect is directly related to the permeability, conductivity, and physical dimensions of the part. Essentially, the instrument “compares” these variations in the test part to conditions in a known sample. Variations in hardness or heat treatment, for example, create a change in permeability; changes in alloy affect conductivity; and significant dimensional changes affect both conductivity and permeability. These changes in the coil result in displayed signals which can be selected based on differences in amplitudes, phase angles, or harmonic distortion, using the Varimac Vi’s thresholds and target regions.
