style="text-indent:25px">渦流測量原理高頻交流信號在測頭線圈中產(chǎn)生電磁場，測頭靠近導體時，就在其中形成渦流。測頭離導電基體愈近，則渦流愈大，反射阻抗也愈大。這個反饋作用量表征了測頭與導電基體之間距離的大小，也就是導電基體上非導電覆層厚度的大小。由于這類測頭專門測量非鐵磁金屬基材上的覆層厚度，所以通常稱之為非磁性測頭。非磁性測頭采用高頻材料做線圈鐵芯，例如鉑鎳合金或其它新材料。與磁感應原理比較，主要區(qū)別是測頭不同，信號的頻率不同，信號的大小、標度關(guān)系不同。與磁感應測厚儀一樣，渦流測厚儀也達到了分辨率0.1um，允許誤差1%，量程10mm的高水平。采用電渦流原理的測厚儀，原則上對所有導電體上的非導電體覆層均可測量，如航天航空器表面、車輛、家電、鋁合金門窗及其它鋁制品表面的漆，塑料涂層及陽極氧化膜。覆層材料有一定的導電性，通過校準同樣也可測量，但要求兩者的導電率之比至少相差3-5倍（如銅上鍍鉻）。雖然鋼鐵基體亦為導電體，但這類任務還是采用磁性原理測量較為合適。</p><p

ferrous非鐵磁性基體，N型的涂層測厚儀采用電渦流原理；來測量用渦流傳感器測量銅、鋁、鋅、錫等基體上的琺瑯、橡膠、油漆、塑料層等。 FN型的涂層測厚儀既采用電磁感應原理，又采用采用電渦流原理，是F型和N型的二合一型涂層測厚儀。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">磁吸力測量原理及測厚儀長久磁鐵（測頭）與導磁鋼材之間的吸力大小與處于這兩者之間的距離成一定比例關(guān)系，這個距離就是覆層的厚度。利用這一原理制成測厚儀，只要覆層與基材的導磁率之差足夠大，就可進行測量。鑒于大多數(shù)工業(yè)品采用結(jié)構(gòu)鋼和熱軋冷軋鋼板沖壓成型，所以磁性測厚儀應用相當廣。測厚儀基本結(jié)構(gòu)由磁鋼，接力簧，標尺及自停機構(gòu)組成。磁鋼與被測物吸合后，將測量簧在其后逐漸拉長，拉力逐漸增大。當拉力剛好大于吸力，磁鋼脫離的一瞬間記錄下拉力的大小即可獲得覆層厚度。新型的產(chǎn)品可以自動完成這一記錄過程。不同的型號有不同的量程與適用場合。這種儀器的特點是操作簡便、堅固耐用、不用電源，測量前無須校準，價格也較低，很適合車間做現(xiàn)場質(zhì)量控制?；窗插儗訙y厚儀廠家</p><p
