Qhov sib txawv ntawm cov txheej thickness gauge thiab ib tug tsis-destructive txheej thickness gauge yog raws li nram no
Qhov sib txawv tseem ceeb ntawm txheej thickness gauges thiab non-destructive txheej thickness gauges yog raws li nram no. Ob txheej txheej thickness gauges thiab non-destructive txheej thickness gauges yog siv los ntsuas lub nominal thickness ntawm cov ntaub ntawv, tab sis muaj qee qhov sib txawv ntawm txheej thickness gauges thiab non-destructive txheej thickness gauges. Wb sib tham txog qhov sib txawv ntawm cov txheej thickness gauges thiab non-destructive txheej thickness gauges.
Qhov sib txawv ntawm cov txheej txheem tsis muaj kev puas tsuaj:
Txheej thickness gauge, tseem ceeb nyob rau hauv lub nominal ua kev lag luam, yog siv los ntsuas lub nominal txheej thickness ntawm hlau los yog yas.
Tsis muaj kev puas tsuaj txheej thickness gauges muab faib ua ob hom: sib nqus thiab eddy tam sim no, thiab tseem muaj cov hlau nplaum eddy tam sim no dual-purpose hom. Feem ntau siv los ntsuas lub nominal txheej thickness ntawm cov hlau substrate, kuj hu ua txheej thickness gauge.
Sib nqus thickness gauges yog tsim los ntsuas lub thickness ntawm coatings ntawm cov hlau nplaum xws li hlau (tsis suav cov hlau nplaum xws li hlau thiab npib tsib xee), thaum cov hlau tsis sib nqus xws li tooj liab, txhuas, thiab tin tsis tuaj yeem ntsuas. Eddy tam sim no thickness gauges yog tsim los ntsuas lub thickness ntawm rwb thaiv tsev txheej hauv qab cov hlau tsis muaj hlau nplaum, xws li tooj liab, txhuas, thiab lwm yam (cov txheej yuav tsum muaj cov ntaub ntawv ntev thiab luv luv).
Cov ntsiab lus saum toj no qhia txog qhov sib txawv ntawm txheej txheej thickness gauges thiab tsis muaj kev puas tsuaj txheej thickness gauges, vam tias yuav pab tau rau lawv daim ntawv thov yav tom ntej.
Qhov sib txawv ntawm cov hlau nplaum (hlau-raws li) thiab eddy tam sim no (tsis yog hlau-raws li) txheej thickness gauges
Txheej thickness gauge sib nqus (hlau-raws li) ntsuas lub thickness ntawm cov hlau tsis muaj hlau nplaum (xws li txhuas, chromium, tooj liab, enamel, roj hmab, xim, thiab lwm yam) ntawm cov hlau nplaum hlau substrates (xws li hlau, hlau, alloys, thiab nyuaj. magnetic hlau)
Txheej thickness gauge eddy tam sim no (tsis yog hlau raws) ntsuas lub thickness ntawm non-conductive coatings ntawm cov hlau tsis sib nqus substrates (xws li tooj liab, txhuas, zinc, tin, thiab lwm yam) (xws li enamel, roj hmab, xim, yas, thiab lwm yam. .).
Sib nqus (hlau-raws li) F-hom:
Ntsuas cov tuab ntawm cov hlau tsis sib nqus ntawm cov hlau nplaum hlau nplaum xws li hlau thiab hlau, xws li xim, hmoov, ntau yam tshuaj tiv thaiv corrosion, plastics, roj hmab, cov khoom siv hluavtaws, phosphating txheej, chromium, zinc, lead, tin, cadmium, lwm yam;
Eddy tam sim no (tsis yog hlau-raws li) N-hom:
Ntsuas lub thickness ntawm tag nrho cov uas tsis yog-conductive txheej ntawm non-ferromagnetic substrates xws li tooj liab, txhuas, thiab stainless hlau, xws li xim, hmoov, ntau yam anti-corrosion txheej, yas, roj hmab, khoom hluavtaws, phosphating txheej, oxide txheej, thiab lwm yam. ;
FNF hom:
Nws yog kev sib xyaw ua ke ntawm F-hom thiab N-hom, feem ntau hu ua dual-purpose thickness gauge.
