Taw qhia rau Siab Sensors

Pressure sensor yog ib qho cuab yeej lossis cov cuab yeej uas tuaj yeem hnov ​​​​lub teeb liab siab thiab hloov lub teeb liab siab rau hauv cov teeb liab muaj hluav taws xob raws li txoj cai lij choj.

Lub siab sensor feem ntau muaj lub siab ntsuas qhov ntsuas thiab lub teeb liab ua haujlwm. Lub siab sensors tuaj yeem muab faib ua qhov ntsuas qhov ntsuas siab, qhov ntsuas qhov sib txawv thiab qhov ntsuas siab siab.

Lub siab sensor yog qhov siv ntau tshaj plaws hauv kev ua lag luam, dav siv nyob rau hauv ntau yam kev lag luam tsis siv neeg tswj ib puag ncig, suav nrog kev txuag dej, hydropower, tsheb ciav hlau, cov tsev ntse, kev tsim khoom tsis siv neeg tswj, aerospace, tub rog, petrochemical, roj Wells, hluav taws xob fais fab. , nkoj, tshuab cuab yeej, pipelines thiab lwm yam lag luam. Nov yog qee cov qauv sensor thiab lawv daim ntawv thov. Kuj tseem muaj lub ntsuas ntsuas kev kho mob.

Pawg:

Lub siab sensor yog ib qho ntawm cov khoom siv dav tshaj plaws. Cov tsoos siab sensor feem ntau yog cov cuab yeej siv tshuab, qhov deformation ntawm cov khoom elastic qhia tau hais tias lub siab, tab sis cov qauv loj loj, qhov loj yog hnyav, thiab cov khoom siv hluav taws xob tsis tuaj yeem muab. Nrog rau txoj kev loj hlob ntawm semiconductor technology, semiconductor siab sensors kuj tau tshwm sim. Nws yog tus cwj pwm los ntawm qhov me me, lub teeb yuag, siab raug thiab zoo kub yam ntxwv. Tshwj xeeb tshaj yog nrog kev txhim kho ntawm MEMS thev naus laus zis, cov khoom siv hluav taws xob semiconductor tau tsim los rau miniaturization, tsawg zog noj thiab muaj kev ntseeg siab.

1. Diffusion silicon siab transmitter.

Diffused silicon siab transmitters yog tsim los ntawm ntim cais silicon piezoresistive siab rhiab ntsiab nyob rau hauv ib tug stainless hlau vaj tse. Nws tuaj yeem hloov tau cov kua los yog roj siab rau hauv cov khoom siv hluav taws xob.

2. Semiconductor piezoresistive yam.

Lub semiconductor piezoelectric impedance diffusion siab sensor tsim ib tug semiconductor deformation siab nyob rau saum npoo ntawm lub wafer, thiab deforms lub wafer los ntawm sab nraud quab yuam (siab), ua rau ib tug piezoelectric impedance nyhuv, thiab converts lub impedance hloov mus rau hauv hluav taws xob teeb liab.

3. Electrostatic peev xwm hom.

Lub peev xwm electrostatic siab sensor yog tsim kom muaj lub peev xwm nruab nrab ntawm tus ncej ruaj khov ntawm cov iav thiab cov ncej txav ntawm silicon, thiab hloov cov hluav taws xob muaj peev xwm hloov pauv los ntawm deformation ntawm tus ncej txav mus rau hauv cov teeb liab hluav taws xob.
