Inductive Resistance Probes

Inductive resistance probes measure a reduction in sensing element thickness by changes in the inductive resistance of a coil in the probe. By using sensing elements with a high magnetic permeability, the magnetic field around the coil is intensified. Any change in thickness of the elements will change the magnetic field encompassing the coil, and thus the corrosion rate may be obtained. Inductive resistance probes require a temperature adjustment similar to electrical resistance probes. The sensitivity of induction resistance probes is higher than with the electrical resistance probes.
