Calibration yuav tsum thiab calibration txoj kev rau txheej thickness gauges
Cov ntawv tuab tuab yog cov txheej txheem tuab siv los txheeb xyuas qhov ua yuam kev thiab qhov sib txawv ntawm cov txheej thickness gauge los yog calibrate lub txheej thickness gauge. Calibration tej yam kev mob ntawm txheej thickness gauge, kub nyob rau hauv lub chav kuaj: 20 degree ± 2 degree, qhov kub thiab txias lub sij hawm sib npaug ntawm daim ntawv thickness thiab gauge thaiv: 2h; Cov av noo hauv chav kuaj: Tsawg dua lossis sib npaug li 65 feem pua thiab lub sijhawm sov so rau qhov ntsuas qhov muag ntsug: tsis pub tsawg dua 15 feeb. Fais fab mov: 220 (1 ± 10%) V, 50Hz.
1 Kev tshwm sim
Yuav tsum muaj: yuav tsum tsis muaj khawb, pob thiab lwm yam tsis xws luag ntawm ob qhov chaw ntawm daim ntawv tuab. Calibration method: Kev soj ntsuam pom.
2 Cov cheeb tsam zoo
Qhov yuav tsum tau muaj: thaj tsam ntawm lub voj voog uas muaj lub vojvoog ntau dua 5 hli yuav tsum tau cim rau ntawm qhov tsis sib xws, thiab thaj tsam ntawm qhov sib txawv ntawm qhov tuab yuav tsum tsis pub tsawg dua 20mm × 20mm. Calibration method: steel kav ntsuas.
Qhov nruab nrab ntawm 3 tus lej.
Calibration method: ntsuas lub thickness ntawm tus qauv thickness daim ntawv nrog peb sib npaug gauge blocks thiab ib tug ntsug optical meter los ntawm txoj kev ncaj nraim los yog kev sib piv txoj kev, ntxuav lub gauge block, thickness daim ntawv, kho qhov muag ntsuas anvil, thiab sojntsuam nrog aviation roj av ua ntej ntsuas, thiab siv nws rau calibration Lub vojvoog ntawm curvature ntawm lub ntsuas ntsuas tsis tsawg tshaj 20 hli. Thaum ntsuas tus pas ntsuas qis, lub ntsuas lub hau yuav tsum maj mam hu nrog cov ntawv tuab tuab los ntawm kev tig ceg kom tiv thaiv kev cuam tshuam ntawm daim ntawv thickness. Cov ntsiab lus calibration yog 5 cov ntsiab lus sib npaug ntawm thaj chaw ua haujlwm (xws li Center point), rau cov ntawv tuab tuab uas tsis muaj cov cim hauv cheeb tsam zoo, thaj chaw zoo yuav tsum nyob rau hauv ib lub voj voog nrog qhov nruab nrab ntawm qhov nruab nrab thiab lub vojvoog tsis pub tsawg dua 10mm.
4 Uniformity yuam kev
Yuav tsum tau: txheem thickness daim ntawv uniformity yuam kev. calibration txoj kev, coj qhov siab tshaj qhov sib txawv ntawm cov thickness nyeem ntawm txhua qhov taw tes thiab qhov nruab nrab thickness tus nqi raws li qhov tsis sib xws ntawm cov ntawv thickness, thiab tus nqi yuav tsum tsis pub tshaj qhov yuav tsum tau muaj nyob rau hauv Table 2.
