4 Calibration Requirements rau Txheej Thickness Gauge
Daim ntawv thickness txheem yog ib qho kev ntsuas thickness siv los ntsuas cov txheej thickness gauges los yog kom paub meej tias qhov qhia yuam kev thiab variability ntawm txheej thickness gauge. Kev ntsuas chav ntsuas cov av noo yog 65 feem pua, cov txheej thickness gauge lub calibration tej yam kev mob yog 20 degree -2 degree rau qhov kub thiab txias, 2h rau daim ntawv thickness kom ncav cuag kub equilibrium nrog lub gauge thaiv, thiab 15min tsawg kawg yog rau lub ntsug optical gauge kom sov. . Kev siv hluav taws xob: 220 (1%) V, 50 Hz.
1 Kev zoo nkauj
Daim ntawv thickness yuav tsum tsis txhob muaj qhov blemishes ntawm nws ob sab, nrog rau khawb, pob, lossis lwm yam flaws. Kev kuaj pom pom yog cov txheej txheem calibration.
2 Kev ua haujlwm hauv cheeb tsam
Qhov cheeb tsam ntawm qhov sib txawv ntawm qhov tuab yuav tsum tsis pub tsawg dua 20mm20mm, thiab thaj tsam ntawm lub voj voog uas muaj lub vojvoog siab tshaj 5 hli yuav tsum tau cim rau ntawm qhov tsis sib xws. Siv lub yardstick steel ua lub calibrator.
Qhov nruab nrab ntawm 3 tus lej.
Lub ntsuas ntsuas, daim ntawv tuab, ntsuas qhov muag qhov muag, thiab kev sojntsuam yuav tsum tau muab ntxuav tag nrho nrog cov roj av ua ntej ntsuas thiab siv rau kev ntsuas. Txoj kev no tuaj yeem siv los ntsuas qhov tuab ntawm daim ntawv tuab txheej txheem siv peb qhov sib npaug ntawm qhov ntsuas qhov sib npaug thiab lub ntsuas qhov muag ntsug. Lub ntsuas ntsuas muaj qhov tsawg kawg nkaus ntawm 20mm lub vojvoog ntawm nkhaus. Txhawm rau kom tsis txhob muaj kev cuam tshuam rau daim ntawv tuab txheej txheem thaum ntsuas pas nrig, cov ceg yuav tsum tau tig kom lub ntsuas lub hau ua rau lub teeb kov nrog daim ntawv.Rau cov ntawv tuab tuab uas tsis muaj cov cim hauv cheeb tsam zoo, thaj chaw zoo yuav tsum nyob hauv ib lub voj voog nrog. qhov chaw raws li qhov chaw nruab nrab thiab ib lub vojvoog tsis pub tsawg tshaj 10mm. Cov ntsiab lus calibration yog 5 cov ntsiab lus sib npaug sib faib thoob plaws hauv cheeb tsam zoo (xws li Center point).
4 Uniformity yuam kev
Standard width sheet uniformity yuam kev yog qhov yuav tsum tau ua. Siv cov txheej txheem calibration, qhov tsis sib xws ntawm cov txheej txheem thickness yog xam raws li qhov sib txawv siab tshaj plaws ntawm cov thickness nyeem ntawm txhua qhov taw tes thiab qhov nruab nrab thickness tus nqi, thiab tus nqi yuav tsum tsis txhob siab tshaj qhov specifications hauv Table 2.
