The Meaning of English Letters in Coating Thickness Gauges
What are the differences between F, N, and FN in coating thickness gauges? F represents a ferromagnetic substrate, and 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, rubber, synthetic materials, phosphating layers, chromium, zinc, lead, aluminum, tin, cadmium, porcelain, enamel, oxide layers, etc. N represents Non ferromagnetic substrate, and the N-type coating thickness gauge adopts the principle of eddy current; To measure enamel, rubber, paint, plastic layers, etc. on substrates such as copper, aluminum, zinc, tin, etc. using eddy current sensors. The FN type coating thickness gauge adopts both electromagnetic induction principle and eddy current principle, and is a two in one coating thickness gauge of F-type and N-type. See above for the purpose. A magnetic thickness gauge with an F-probe; FN refers to a magnetic and eddy current dual-purpose 2-in-1 coating thickness gauge with two probes. Function: Measure the thickness of non-magnetic coatings on magnetic objects and non-conductive coatings on non-magnetic metal substrates. Application: Use magnetic sensors to measure non-magnetic coatings and coatings on ferromagnetic metal substrates such as steel and iron, such as paint, powder, plastic, rubber, synthetic materials, phosphating layers, chromium, zinc, lead, aluminum, tin, cadmium, porcelain, enamel, oxide layers, etc. Measure enamel, rubber, paint, plastic layers, etc. on substrates such as copper, aluminum, zinc, tin, etc. using eddy current sensors. Widely used in inspection fields such as manufacturing, metal processing, chemical industry, and commercial inspection.
