Metrology Institutions daws teeb meem
Cov kev sib tw ntsib los ntawm Metrology Institutions hauv lawv txoj haujlwm
1. Cov cuab yeej txwv ntawm Micro-siab thiab Siab-siab Scenarios
Micro-siab calibration (xws li, ± 10kPa) yuav tsum tau them nyiaj microbarometers lossis siab -precision digital siab ntsuas ntsuas, txawm hais tias cov khoom siv no raug nqi thiab pheej yig rau ib puag ncig kev co. Lwm yam khoom siv yuav tsis ua tiav tag nrho - ntau yam kev pab cuam hauv micro- siab ntau.
Rau qhov siab siab, qhov kev sib tw yog 250MPa thiab siab dua
2. Qhov teeb meem ntawm kev xaiv tus qauv thiab kev them nyiaj ntau
Qhov tseeb ntawm qhov siab - cov cuab yeej ntsuas qhov tseeb (piv txwv li, 0.01% cov ntsuas ntsuas digital) rau qhov ntsuas tag nrho tsis sib npaug. Piv txwv li, 0.01% tus qauv ntsuas muaj qhov tso cai yuam kev ntawm ± 0.1kPa ntawm 1MPa, tab sis qhov no nce mus rau ± 1kPa ntawm 10MPa. Thaum calibrating 0.1% siab sensor nrog 10MPa ntau, siab dua -qib ntsuas ntsuas (piv txwv li, 0.005%) yuav tsum raug xaiv, ua rau ntau tshaj peb npaug ntawm cov khoom siv.
3. Kev sau ntawv thiab kev suav yuam kev
Cov txheej txheem calibration ib txwm cia siab rau kev nyeem phau ntawv ntawm cov qauv ntsuas kev nyeem ntawv thiab kev suav yuam kev. Kev txheeb xyuas los ntawm ib lub tsev kawm ntawv qhia tau hais tias qhov kev ua yuam kev hauv phau ntawv sau txog 3.2%, thaum qhov kev suav qhov yuam kev yog 1.7%. Piv txwv li, nyob rau hauv kev xam qhov yuam kev rov qab rau lub precision siab gauge, ib tug neeg ua hauj lwm cov neeg ua hauj lwm tshem tawm cov ntaub ntawv taw tes, uas ua rau ib tug incorrect daim ntawv pov thawj. Qhov no yuav tsum tau rov-calibration thiab them nyiaj rau cov neeg siv khoom poob.
Peb qhov kev daws teeb meem
- Tsis siv neeg tuag hnyav tester: (-0.1-1400)MPa; (-0.1-250)MPa qhov tseeb: 0.005%, (250-1400)MPa qhov tseeb 0.05% -0.01%
- Digital siab calibrator: (-0.1-250) MPa qhov tseeb: 0.02% lossis tsawg dua
- Tsis siv neeg siab calibrator: (-0.098-100) MPa qhov tseeb: 0.02% lossis tsawg dua
- Tuag yuag tester:
(-0.1-640)MPa
(-0.1-250) MPa qhov tseeb 0.005%
(250-640) MPa qhov tseeb: 0.05% -0.01%
Tag nrho cov kev daws teeb meem saum toj no tuaj yeem ua tau raws li qhov yuav tsum tau ua hauv kev ua haujlwm thoob plaws txhua qhov ntau, txhawb nqa ob qho tib si phau ntawv thiab kev siv ua haujlwm.
