Nyob rau hauv tag nrho cov saw muaj kev sib tw ntawm kev tshawb nrhiav roj av, chaw khaws khoom, thiab ua haujlwm rau ib puag ncig uas muaj kev sib raug zoo ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug rau qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov raug ntawm qhov tseeb ntawm kev sib raug zoo thiab kev ruaj ntseg ntawm cov sensors. Cov kev xav tau no yog cuam tshuam nrog kev nyab xeeb rau kev nyab xeeb, kev ua haujlwm, thiab kev lag luam muaj txiaj ntsig ntawm cov roj thiab roj kev loj hlob.
I. Qhov yuav tsum tau ua: Kev soj qab qhov kawg ntawm "millimeter- qib" rau "micron- qib"
1. Cov ntsiab lus tseem ceeb yog qhov ntsuas muaj ntau dua kev muaj cov xwm txheej.
٭ Kev Ntsuas Ntsuas Qhov Ntsuas:Mainstrez quartez crystal siab sensors yuav tsum tau ua tiav ± 0.02% fs0, {{{4 4 ± 0.2% fs0.5% FS).
٭ Teeb meem: Mus txog 0.0001psi (kwv yees li 0.7pa), sib npaug los kuaj xyuas lub siab hloov tsim los ntawm 1 {} 'meter' meter kem ntawm dej. Qhov no ua tau raws li cov cai rau kev sim tshuaj rau kev sim tshuaj permeability (nyob rau hauv cov xwm txheej ntawm 200℃yuav tsum yog<0.001%FS).
2.Kev tsom xam ntawm qhov yuav tsum tau nyob hauv cov xwm txheej raug

Ii. Kev Nyab Xeeb Yuav Tsum Tau: Ua tiav "Xoom Drift" Hauv Huab Ib puag ncig
1. Qhov ntsuas kub sov thiab tag nrho lub neej lub neej ruaj khov
Qhov Twg:
Maintains temperature drift ≤ 0.01% FS/℃ across a wide temperature range of -50°C (Arctic drilling) to 225°C (high-temperature deep wells), far superior to traditional sensors (>0.1% fs / degree).
Nruab nrog qhov ntsuas kub them nyiaj algorithms kom ua tiav cov kev sib koom ua ke (piv txwv li kev ntsuas kub siab dua (piv txwv li cov kev ntsuas kub siab dua tshiab)
Ntev -} lub sij hawm ruaj khov:
Txhua xyoo Drift <0.1% FS, tsuas yog 1/20 ntawm cov kev ua yeeb yam (ib xyoo drift 1% fs ~ 2% fs).
Kev co thiab kev poob siab tshaj plaws: hla 50 qhov kev sib tw ua kom nruj (ISO 167 txuj ci siab)
Xaus: Rov ua dua lub 'Qab nthab ntawm qhov tseeb thiab ruaj khov' rau kev lag luam muaj sensors
The requirements for the accuracy and stability of pressure sensors in the oil industry fundamentally stem from the urgent need for "reliable decision-making in extreme environments":
Kev ua yog:Yuav tsum mus txog aerospace - ntsuas cov qauv kev ntsuas (± 0.02% fs) kom ntes cov txheej txheem kev kawm ntawv xws li kev tiv thaiv cov kev kho kom zoo thiab ua kom zoo dua qub.
Ruaj khov:Yuav tsum tau tshaj tawm cov tub rog - kev ua haujlwm ib puag ncig (}}}}}}}
These "double-high" requirements have made quartz crystal pressure sensors a "must-have product" in the oil industry. Lawv cov kev ntsuas tsis yog tsuas yog ua tau cov ntsuas ntsuas tab sis kuj yog "txoj sia" rau kom ua kom muaj kev nyab xeeb thiab siv tau zoo ntawm cov roj thiab roj.
