Measuring Principles
The gauge uses magnetic and eddy current thickness measurement methods. The non-
destructive measurement can measure the thickness of magnetic metals (such as steel, iron,
alloy steel) and hard magnetic and non-magnetic coatings (such as aluminium, chromium, copper,
enamel, rubber, paint, etc.); the thickness of non-conductive coatings (such as enamel paint,
plastic, rubber, etc.) of non-magnetic metals (such as copper, aluminium, zinc, tin, etc.).
Magnetic measurement method:
•
When the (Fe) probe comes into contact with a metal surface, the magnetic field will be
amplified. It then generates a voltage in a second coil (measuring coil). This voltage
depends on the distance from the metal surface. If a non-magnetic coating is present,
a defined distance results between the probe and the metal surface, and thus a defined
coil voltage. This is electronically evaluated and digitally displayed as the coating
thickness.
Eddy current measuring method:
•
When the (NFe) probe with its alternating field approaches a non-ferrous metal, an
alternating current – called the eddy current – is induced in this metal. This produces
another electro-magnetic alternating field in the opposite direction, weakening the
original field. The effect in the probe is a change of inductiveness. By placing the probe
in contact with the coating, a defined distance between the probe and the non-ferrous
metal results, thus leading to a defined inductivity. This will be electronically evaluated
and digitally displayed as the coating thickness.
