Pressure sensors yog ib qho tseem ceeb hauv ntau lub lag luam, muab lub peev xwm los ntsuas qhov tseeb thiab ntseeg siab hauv ntau yam kev siv.Ib hom kev kub siab sensor uas tau txais koob meej nyob rau hauv xyoo tas los no yog iav micro-melt sensor, uas yog thawj zaug tsim los ntawm California Institute of Technology hauv 1965.
Lub iav micro-melt sensor nta lub iav iav hmoov sintered rau sab nraum qab ntawm 17-4PH qis-carbon steel kab noj hniav, nrog cov kab noj hniav nws tus kheej ua los ntawm 17-4PH stainless hlau.Qhov kev tsim no tso cai rau kom muaj kev kub ntxhov ntau dhau thiab ua haujlwm tau zoo rau kev poob siab sai.Tsis tas li ntawd, nws tuaj yeem ntsuas cov kua dej uas muaj me me ntawm impurities yam tsis tas yuav muaj roj lossis cais cov diaphragms.Kev tsim kho stainless hlau tshem tawm qhov xav tau ntawm O-rings, txo qhov kev pheej hmoo ntawm qhov kub thiab txias tso tawm.Lub sensor tuaj yeem ntsuas txog 600MPa (6000 bar) nyob rau hauv cov xwm txheej kub siab nrog cov khoom siab tshaj plaws ntawm 0.075%.
Txawm li cas los xij, ntsuas qhov me me nrog lub iav micro-melt sensor tuaj yeem nyuaj, thiab nws feem ntau tsuas yog siv rau kev ntsuas ntau dua 500 kPa.Nyob rau hauv daim ntawv thov qhov twg high voltage thiab high precision ntsuas yog tsim nyog, lub sensor yuav hloov ib txwm diffused silicon siab sensors nrog txawm ntau dua efficiency.
MEMS (Micro-Electro-Mechanical Systems) technology-based pressure sensors yog lwm hom sensor uas tau txais kev nyiam nyob rau xyoo tas los no.Cov sensors no yog tsim los siv micro/nanometer-loj silicon strain gauges, uas muaj cov zis siab rhiab heev, kev ua haujlwm ruaj khov, txhim khu kev qha batch ntau lawm, thiab zoo rov ua dua.
Lub iav micro-melt sensor siv cov thev naus laus zis siab heev uas lub ntsuas ntsuas silicon yog sintered mus rau 17-4PH stainless hlau elastic lub cev tom qab lub khob tau yaj ntawm qhov kub siab tshaj 500 ℃.Thaum theelastic bodyundergoescompression deformation, nws generates hluav taws xob teeb liab uas yog amplified los ntawm ib tug digital them amplification Circuit Court nrog ib tug microprocessor.Lub teeb liab tso zis yog ces yuav tsum tau them nyiaj rau qhov kub thiab txias siv digital software.Thaum lub sij hawm tus txheej txheem purification ntau lawm, cov tsis yog nruj me ntsis tswj kom tsis txhob muaj qhov kub thiab txias, av noo, thiab mechanical qaug zog.Lub sensor muaj cov lus teb ntau zaus thiab kev ua haujlwm kub ntau, ua kom muaj kev ruaj ntseg mus ntev hauv kev lag luam hnyav.
Qhov ntse tau them nyiaj Circenation Circenic muab faib rau ob peb chav nyob rau hauv ntau chav tsev, thiab cov nqi xoom thiab tus nqi them nyiaj rau txhua chav tsev raug them.Thaum siv, cov txiaj ntsig no tau sau rau hauv txoj kev tso tawm analog uas cuam tshuam los ntawm qhov kub thiab txias, nrog rau txhua qhov ntsuas kub yog qhov "calibration temperature" ntawm transmitter.Lub digital Circuit Court ntawm lub sensor yog ua tib zoo tsim los tswj cov yam ntxwv xws li zaus, electromagnetic cuam tshuam, thiab surge voltage, muaj zog tiv thaiv kev cuam tshuam, kev siv hluav taws xob dav dav, thiab kev tiv thaiv polarity.
Lub siab chamber ntawm lub iav micro-melt sensor yog ua los ntawm 17-4PH stainless hlau, tsis muaj O-rings, welds, los yog leaks.Lub sensor muaj qhov muaj peev xwm ntawm 300% FS thiab tsis ua haujlwm siab ntawm 500% FS, ua rau nws zoo tagnrho rau kev siv lub zog siab dhau.Txhawm rau tiv thaiv kev poob siab tam sim ntawd uas yuav tshwm sim hauv cov tshuab hydraulic, lub sensor muaj cov khoom siv tiv thaiv kev tiv thaiv.Nws yog dav siv nyob rau hauv hnyav industries xws li engineering machinery, tshuab cuab yeej kev lag luam, metallurgy, tshuaj kev lag luam, fais fab kev lag luam, high-purity gas, hydrogen siab ntsuas, thiab ua liaj ua teb machinery.
