Defelsko Metal Coating Thickness Gauges ...
The Probe range offers Magnetic Induction measurement for use over ferrous metals and Eddy Current for non-ferrous.
Coating thickness is an important variable that plays a role in product quality, process control, and cost control. Measurement of film thickness can be done with many different instruments. Understanding the equipment that is available for film thickness measurement and how to use it is useful to every coating operation.
The issues that determine what method is best for a given coating measurement include the type of coating, the substrate material, the thickness range of the coating, the size and shape of the part.
The PosiTector 6000 offers users the best technology in the world with which to measure coating thicknesses on metallic substrates. There are a multitude of options with regards to probe specification, data treatment and complimentary technologies.
Two predominant technologies are used for coating thickness measurements on metal substrates. The choice of technology depends on the nature of the substrate ferrous or non-ferrous
Magnetic Induction
Used for ferrous substrates; magnetic induction instruments use a permanent magnet as the source of the magnetic field. A Hall effect generator or magneto resistor is used to sense the magnetic flux density at a pole of the magnet.
Electromagnetic induction instruments use an alternating magnetic field. A soft, ferromagnetic rod wound with a coil of fine wire is used to produce a magnetic field. A second coil of wire is used to detect changes in magnetic flux.
These electronic instruments measure the change in magnetic flux density at the surface of a magnetic probe as it nears a steel surface. The magnitude of the flux density at the probe surface is directly related to the distance from the steel substrate. By measuring flux density the coating thickness can be determined.
Eddy Current
Eddy current techniques are used to non-destructively measure the thickness of non-conductive coatings
on nonferrous metal substrates. A coil of fine wire conducting a high frequency alternating current (above 1 MHz) is used to set up an alternating magnetic field at the surface of the instrument's probe. When the probe is brought near a conductive surface, the alternating magnetic field will set up eddy currents on the surface. The substrate characteristics and the distance of the probe from the substrate (the coating thickness) affect the magnitude of the eddy currents. The eddy currents create their own opposing electromagnetic field that can be sensed by the exciting coil or by a second, adjacent coil.
