What do F, N and FN stand for on coating thickness gauges?
The coating thickness gauge can non-destructively measure the thickness of non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) and non-magnetic coatings on magnetic metal substrates (such as steel, iron, alloys and hard magnetic steel, etc.) The thickness of the non-conductive coating (such as enamel, rubber, paint, plastic, etc.) on the metal substrate (such as copper, aluminum, zinc, tin, etc.). So what do F, N and FN stand for in coating thickness gauges? Shenzhen Yuanhengtong Technology Co., Ltd. will introduce to you in detail:
F stands for ferrous ferromagnetic substrate. The F-type coating thickness gauge uses the principle of electromagnetic induction to measure non-ferromagnetic coatings and coatings on ferromagnetic metal substrates such as steel and iron, such as paint, powder, plastic, and rubber. , synthetic materials, phosphate layer, chromium, zinc, lead, aluminum, tin, cadmium, porcelain, enamel, oxide layer, etc.
N stands for Non-ferrous non-ferrous substrate. The N-type coating thickness gauge adopts the principle of eddy current; it uses eddy current sensors to measure enamel, rubber, paint, plastic layers, etc. on copper, aluminum, zinc, tin and other substrates.
The FN type coating thickness gauge adopts both the electromagnetic induction principle and the eddy current principle. It is a two-in-one coating thickness gauge of F type and N type.
Coating thickness gauges can generally measure how thick a coating is
The maximum range of imported coating thickness gauge can reach 120mm
When choosing a coating thickness gauge, the larger the measuring range, the better. The larger the measuring range, the larger the probe and the lower the accuracy.
The common coating thickness gauge range is 0-1250 μm, and the PD-CT2 high-precision coating thickness gauge is 0-1500 μm, with an error of up to 1%.
If it is a coating measurement, you need to choose a special coating thickness gauge to measure the coating. You cannot use a paint film thickness gauge.
Standard test pieces of corresponding thickness are also required.
