Kev lag luam kov cov lus qhia, raws li lub npe qhia, feem ntau yog siv rau hauv cov khoom lag luam, thiab kev lag luam ib puag ncig sov so. Lub sijhawm no, yuav tsum muaj qhov ntsuas kub dav dav. Cov khoom siv kov tau dhau los ua qhov kev sim nruj thiab tuaj yeem ua haujlwm ruaj khov hauv qhov chaw kub thiab tsis kub.
Tam sim no, feem ntau siv nyob rau hauv kev lag luam kov cov lus qhia yog resistive kov cov ntxaij vab tshaus thiab capacitive kov cov ntxaij vab tshaus. Tab sis nyob rau hauv ib puag ncig hnyav, nws yuav cuam tshuam tsis zoo. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub vijtsam capacitive yog siv lub ntsuas hluav taws xob los ua kom muaj qhov hluav taws xob ntawm tus neeg xyuas pib ntawm lub vijtsam, yog li tsim cov txheeb ze tam sim no, thiab ntsuas qhov kov ntawm qhov deb. Nyob rau hauv cov ntaub ntawv ntawm qhov kub thiab txias, daim tawv nqaij nto ntawm ob txhais tes muaj cov ntsiab lus tsis muaj noo noo, thiab qhuav thiab txias ntawm daim tawv nqaij muaj tsis zoo conductivity. Nyob rau tib lub sijhawm, thaum qhov kub ntawm qhov ntsuas kub qis, qhov kev ua haujlwm ntawm lub sensor tseem yuav raug cuam tshuam, thiab cov khoom siv kov tsis tuaj yeem paub qhov kov txoj haujlwm zoo, ua rau lub vijtsam kov ua haujlwm tsis zoo. Kev khiav hauj lwm kub ntawm lub vijtsam kov feem ntau yog nyob nruab nrab ntawm -5 degree thiab 60 degree, tshwj xeeb tshaj yog nyob rau lub caij ntuj no, thaj tsam sab qaum teb raug cuam tshuam ntau dua.
Cov tshuaj tiv thaiv kov tsis tshua muaj kev cuam tshuam. Ntawm qhov tod tes, vim yog siv cov txheej txheem sib txawv, micro-circuit ntawm lub vijtsam kov tau txuas nrog kev ua haujlwm, uas tsis muaj zog cuam tshuam los ntawm qhov kub thiab txias. Ntawm qhov tod tes, cov txheej txheem thev naus laus zis ntawm cov tshuaj tiv thaiv tiv thaiv yog qhov paub tab, thiab cov ntaub ntawv siv tau tag nrho tuaj yeem tiv taus qhov kev sim thiab txuas ntxiv mus. Qhov ntsuas kub ntawm lub vijtsam tiv thaiv yuav tsum nyob nruab nrab ntawm -20 degree ~ 65 degree, uas tuaj yeem ua tau raws li feem ntau ntawm kev siv ib puag ncig.
Tsis tas li ntawd, kev lag luam kov cov lus pom muaj xws li infrared kov cov ntxaij vab tshaus thiab nto acoustic yoj cov ntxaij vab tshaus.
Qhov tseeb ntawm lub vijtsam kov infrared yog tsis muaj kev cuam tshuam tam sim no, qhov hluav taws xob thiab hluav taws xob zoo li qub, thiab tsim nyog rau ntau yam ib puag ncig nrog lub teeb paug. Txawm li cas los xij, lub vijtsam kov infrared raug txwv vim nws lub sensor ib leeg, yooj yim rau kev puas tsuaj thiab kev laus, thiab qhov kov interface tsis tuaj yeem tiv taus cov pa phem, kev puas tsuaj, thiab kev saib xyuas nyuaj. Thaum qhov kub thiab txias tsis tshua muaj siab, cov hluav taws xob zoo li qub tau tsim thaum siv cov khoom lag luam nthuav tawm nyiam cov plua plav, yog li cuam tshuam rau kev siv. Haum rau siv nyob rau hauv aerospace teb.
Nws qhia tau hais tias lub sonic kov lub vijtsam muaj lub ntsiab lus siab heev, lub teeb xa tawm tuaj yeem ncav cuag 92 feem pua, kev tiv thaiv khawb, kev puas tsuaj kuj yog qhov zoo tshaj plaws, cov lus teb yog rhiab heev, thiab qhov tseeb yog kiag li tsis cuam tshuam los ntawm ib puag ncig yam xws li kub thiab txias. av noo. Piv txwv li, tus nqi ntawm kev tsim kho thiab kev saib xyuas kuj yog siab heev. Nto acoustic yoj cov ntxaij vab tshaus yuav tsum tau saib xyuas tsis tu ncua. Yog tias cov plua plav, roj stains lossis cov kua dej muaj paug rau ntawm qhov chaw ntawm lub vijtsam kov, lub yoj taw qhia zawj ntawm qhov chaw ntawm lub vijtsam kov yuav raug thaiv, ua rau lub suab nthwv dej tsis tuaj yeem tawm ib txwm lossis ua rau lub waveform hloov thiab maub los tsis tuaj yeem paub nws kom raug. Yog li ntawd, kev saib xyuas nruj yuav tsum tau them rau ib puag ncig kev nyiam huv, thiab qhov chaw ntawm lub vijtsam kov yuav tsum tau so ntau zaus kom nws du thiab huv si, thiab kev ua kom tiav thiab huv si yuav tsum tau ua tsis tu ncua. Yog hais tias qhov saum npoo ntawm sonic screen condenses los yog tau oily nyob rau hauv lub caij ntuj no, nws yuav nyuaj heev los ntxuav.
Resistive cov ntxaij vab tshaus thiab cov ntxaij vab tshaus capacitive uas tuaj yeem lees paub dav tom qab txhua tus muaj lawv qhov zoo kom pom tau. Kov xav tias cov cuab yeej kov ntse, txhawb kev hloov kho, qhov loj tshaj kaum-taw tes kov capacitive npo yog xaiv los ntawm lub neej ntawd, thiab 5-wire resistive touch screen yog xaiv tau.
Qhov saum npoo av acoustic yoj muaj qhov pom tseeb thiab qhov pom kev zoo. Ua tau zoo heev, zoo khawb kuj (muaj cov zaj duab xis nto txheeb ze rau resistors, capacitors, thiab lwm yam). Teb. Tsis cuam tshuam los ntawm ib puag ncig yam xws li kub thiab av noo, kev daws teeb meem siab, lub neej ntev (50 lab lub sijhawm hauv kev saib xyuas zoo); High light transmittance (92 feem pua), tuaj yeem tswj cov duab meej thiab ci zoo; tsis muaj drift, muaj rugged zaub xwb Nws yuav tsum tau calibrated ib zaug thaum lub installation; muaj peb axis (xws li lub siab axis) teb, uas yog tam sim no siv ntau nyob rau hauv pej xeem qhov chaw.
Txawm hais tias qhov dav qhov kub thiab txias tuaj yeem hloov mus rau qhov kub thiab txias, peb kuj yuav tsum tau them sai sai rau nws thaum siv. Vim yog vim li cas thaj chaw, qhov kub ntawm qhov sib txawv ntawm sab qaum teb thiab sab qab teb yog qhov loj, thiab cov phiaj xwm kev tiv thaiv yuav tsum tau ua kom ntseeg tau tias kev siv ib txwm siv ntawm cov khoom siv kov.
