Cov ntsiab lus tshwj xeeb rau kev txheeb xyuas txheej thickness gauges los ntawm kev pom zoo
Txheej thickness gauge yog ib hom kev ntsuas uas tsis muaj kev puas tsuaj. Piv txwv li, yog tias cov yeeb nkab steel yog pleev xim rau xim, peb tsis tas yuav khawb tawm cov xim, peb tuaj yeem kuaj ncaj qha nrog cov txheej thickness ntsuas kom tau cov txheej thickness, uas yog yooj yim heev.
Cov txheej txheej tuab tuaj yeem ntsuas qhov tuab ntawm cov hlau tsis sib nqus (xws li txhuas, chromium, tooj liab, enamel, roj hmab, xim, thiab lwm yam) Lub thickness ntawm cov txheej uas tsis yog-conductive (xws li enamel, roj hmab, xim. , yas, thiab lwm yam) ntawm cov hlau substrate (xws li tooj liab, txhuas, zinc, tin, thiab lwm yam). Cov txheej thickness gauge muaj cov yam ntxwv ntawm me me ntsuas yuam kev, muaj kev ntseeg siab, zoo stability, thiab ua haujlwm yooj yim. Nws yog ib qho tseem ceeb ntawm kev ntsuam xyuas cov cuab yeej rau kev tswj thiab ua kom cov khoom zoo. Nws yog dav siv nyob rau hauv kev tsim, hlau ua, tshuaj lom neeg kev lag luam, Khoom muag tshuaj xyuas thiab lwm yam kev xeem teb.
Kev sib raug zoo ntawm cov khoom siv hauv paus thiab txheej txheej nruab nrab ntawm cov txheej txheem txheej thickness ntsuas raws li lub hauv paus ntsiab lus ntawm "sib nqus thiab tsis sib nqus, tsis sib nqus thiab tsis-conductive" (Ceeb toom: ntsuas qhov tuab ntawm cov txheej tsis sib nqus ntawm lub Cov khoom siv sib nqus, ntsuas qhov tuab ntawm cov khoom tsis sib nqus ntawm cov khoom tsis sib nqus ntawm cov insulating npog). Ntawm lawv, "magnetic" yog hais txog cov hlau nplaum, uas yog sawv cev los ntawm F es tsis yog NF, thiab "conductive" yog hais txog cov khoom siv hluav taws xob, feem ntau tsis yog xim hlau.
F probe sawv cev rau ferromagnetic substrate. F-hom txheej thickness gauge txais 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.
NF probes sawv cev tsis yog-ferromagnetic substrates, thiab NF-hom txheej thickness gauges siv lub hauv paus ntsiab lus ntawm eddy tam sim no; ntsuas 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. Siv saib saum toj no. Sib nqus thickness gauge nrog F-probe;
FN yog hais txog qhov sib nqus thiab eddy tam sim no 2-hauv-1 txheej thickness ntsuas nrog ob qhov kev sojntsuam.
