The meaning of the letters in the coating thickness gauge
What are the differences between F, N and FN in coating thickness gauges? 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 eddy current principle; 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. See above for usage. A magnetic thickness gauge with one F probe; FN refers to a two-in-one coating thickness gauge with two probes, both magnetic and eddy current. Function: Measure the thickness of non-magnetic coatings on magnetically permeable objects and non-conductive coatings on non-magnetic metal substrates. Application: Use magnetic sensors to measure non-ferromagnetic coatings and coatings on ferromagnetic metal substrates such as steel and iron. , such as: paint, powder, plastic, rubber, synthetic materials, phosphate layer, chromium, zinc, lead, aluminum, tin, cadmium, porcelain, enamel, oxide layer, etc. Use eddy current sensors to measure enamel, rubber, paint, plastic layers, etc. on copper, aluminum, zinc, tin and other substrates. It is widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other inspection fields.
