Nyob rau hauv lub teb ntawm kev muaj tshuab automation, Aerospace, lub zog tshawb nrhiav, thiab lwm yam kev ntsuas siab ncaj qha cuam tshuam rau kev ua tau zoo thiab kev nyab xeeb ntau lawm. Cov teeb tsa ib txwm muaj kev txwv tsis pub siv, kev cuam tshuam ib puag ncig, thiab ntev}}}}} Tuab ruaj khov, ua rau nws muaj kev ruaj ntseg.
Lub siab - precision silicon resononant siab sensor, thiab}} kub}}} kub}} Kev hloov kho ntawm kev lag luam, muab cov hom lag luam - kev daws tshiab rau kev ntsuas kom zoo.
Cov Silicon Resononant Siab Sensor tuaj yeem ua tiav qhov tseeb ntawm "ib lub kaum- {txhiab lub ntsiab lus thiab thev naus laus zis. Thaum sab nraud siab ua rau cov silwbon diaphragm ntawm sensor, sivhragm yuav deform. Qhov no deformation no yuav ua rau muaj kev hloov pauv ntawm qhov zaus ntawm lub nqaj uas yog resonant. Nws yog ib yam li thaum ua si cov hlua ntawm cov twj paj nruas, qhov kev hloov pauv ntawm cov hlua khi yuav ua rau muaj kev hloov pauv hauv lub suab. Los ntawm kev ntsuas ntsuas ntawm cov zaus hloov ntawm cov nqaj resonant, lub sensor tuaj yeem suav qhov ntau ntawm cov kev siab sab nraud.

Hauv cov txheej txheem no, cov electrostatic excitation thiab capacitance nrhiav kom paub txog tshuab ua si ib lub luag haujlwm tseem ceeb. Kev xav tau electrostatic zoo li muab cov kev tsav tsheb txuas ntxiv "rau lub nqaj resonant, ua rau tshee tshee, ua kom nws tshee me me; Kev siv tshuaj kom zoo li ntse "tus neeg" uas tuaj yeem ntes cov kev hloov pauv hloov maj mam nyob hauv qhov chaw ntawm lub nqaj resonant. Qhov ob ntxiv ua ke thiab sib koom ua ke kom ntsuas qhov ntsuas siab yog qhov tseeb ntawm cov ntsuas yog qhov tseeb ntawm ± 0.01% FS. Cov tswvyim no txhais li cas? Nws yog sib npaug kom muaj kev ua yuam kev tsuas yog 0.1 kpa thaum ntsuas ib qho chaw ntawm lub siab. Xws li cov kev ua yuam kev me me yog qhov txaus kom tau raws li cov cai ntawm feem ntau ntawm cov siab {6} pre} precision ntsuas science.
Ntxiv nrog rau nws qhov siab, lub siab realonant siab sensor kuj muaj ntau cov tseem ceeb uas ua rau nws sawv tawm ntawm ntau cov siab tshaj. Nyob rau hauv cov nqe lus ntawm tus kheej kub {{}} eve} Kev them nyiaj, nws tau ua tiav qhov kub kom tsawg dua rau qhov ntsuas kub kom nce qib ± 100 pecm tauj ib xyoos. Qhov no txhais tau tias txawm nyob hauv ib puag ncig nrog qhov ntsuas kub uas kub ntawm lub sensor tuaj yeem nyob tsis yooj yim, thiab nws yuav tsis tsim cov kev ua yuam kev loj, thiab nws yuav tsis tsim cov kev ua yuam kev loj vim kub. Nyob rau hauv cov nqe lus ntawm anti - sib cuam tshuam, cov Silicon Resononant Siab Sensor tawm cov teeb liab zaus. Cov teeb liab zoo no tsis tas yuav analog - rau- hack digital hloov dua siab tshiab. Ib yam li "teeb liab batthouse", nws muaj lub zog anti - sib cuam tshuam ntawm nws tus kheej. Piv nrog rau lwm hom sensors, nws anti- Electromagnetic ib puag ncig muaj zog nyob rau hauv ib lub zog hluav taws xob ib puag ncig thiab ua kom cov ntaub ntawv ntsuas.
Thaum ntsib cov pej xeem puag ncig, cov lus si silicon realonant siab sensor kuj tseem ntshai. Nws cov kev ua haujlwm kub ntau yam npog los ntawm -55℃rau +125 degree. Txawm hais tias nws yog nyob rau hauv cov dej txias txias heev, lub suab thaj teb yuav tsum muaj ntau txoj kev tswj hwm ib puag ncig, nws tuaj yeem ua haujlwm siab rau ib puag ncig ntau ib puag ncig rau cov haujlwm ruaj khov ntawm cov cuab yeej siv tau.
Nrog rau kev txhim kho sai ntawm kev tsim khoom lag luam hauv ntau cov khoom siv, uas tseem tsav lub siab {{Precision siab sensors. Txhawm rau kom tau zoo dua cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom, peb cov ntaub ntawv sib txawv, peb yuav xaiv cov lus qhia ODM tshwj xeeb, thiab lwm yam kev ua tau zoo thiab kev ntseeg tau ntawm cov sensors.
