Qhov sib txawv ntawm F, N thiab FN hauv txheej thickness ntsuas
F stands rau ferrous ferromagnetic substrate. F-hom txheej thickness gauge siv lub hauv paus ntsiab lus ntawm electromagnetic induction los ntsuas non-ferromagnetic coatings thiab coatings ntawm ferromagnetic hlau substrates xws li hlau thiab hlau, xws li: xim, hmoov, yas, roj hmab, khoom siv hluavtaws, phosphating txheej, chromium, zinc, txhuas, txhuas, tin, cadmium, porcelain, enamel, oxide txheej, thiab lwm yam.
N stands rau Non-ferrous non-ferrous substrate, thiab N-hom txheej thickness gauge txais lub hauv paus ntsiab lus ntawm eddy tam sim no; ntsuas cov enamel, roj hmab, xim, txheej yas, thiab lwm yam ntawm tooj liab, txhuas, zinc, tin thiab lwm yam substrates nrog eddy tam sim no sensors.
FN hom txheej thickness gauge txais ob lub hauv paus ntsiab lus ntawm electromagnetic induction thiab lub hauv paus ntsiab lus ntawm eddy tam sim no. Nws yog ob-hauv-ib txheej thickness ntsuas ntawm F hom thiab N hom.
