Technical Sheet

Product Description

These gauges are used to measure non-magnetic layers on magnetic (ferrous) surfaces. Magnetic induction instruments use a permanent magnet to generate a magnetic field. A magneto-resistor or Hall-effect generator is used to sense the magnetic flux density at a pole of the magnet. Electromagnetic induction instruments use an alternating magnetic field. By measuring flux density the coating thickness or layer thickness can be determined.
