CM8828FN coating thickness gauge principle:

The CM8828FN Thickness Gauge utilizes both magnetic and eddy current measurements to nondestructively measure the thickness of non-magnetic coatings on magnetic metal substrates such as steel, iron, alloy and hard magnetic steel (eg, chromium, zinc, Copper, aluminum, enamel, rubber, paint, etc.) and non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.) on the thickness of non-conductive coating (such as: enamel, rubber, paint, plastic, etc.).

A) Magnetic method (F type probe)

When TT280A coating thickness gauge touch probe and the cover layer, the probe and the magnetic metal matrix form a closed magnetic circuit, due to the presence of non-magnetic coating, so that the magnetic resistance of the magnetic circuit changes by measuring the change can be derived cover thickness of.

B) eddy current method (N type probe)

The use of high-frequency alternating current in the coil to produce an electromagnetic field, when the probe and the cover contact, the metal matrix generated eddy current, and probe feedback in the role of the coil, by measuring the size of the role of feedback can be derived coating thickness of.
