XDB100 Piezoresistive Monolithic Ceramic Pressure sensor

Kufotokozera Kwachidule:

YH18 ndi YH14 mndandanda wa ceramic pressure sensors imagwiritsa ntchito zida zapadera za ceramic ndi njira zapamwamba zopangira. Amawonetsedwa ndi kukana kwa dzimbiri kwapadera, kutha kwa kutentha kwabwino, kasupe koyenera, komanso kutchinjiriza kwamagetsi odalirika. Zotsatira zake, makasitomala ochulukirachulukira akusankha masensa a ceramics ngati njira yabwinoko kuposa zida zachikhalidwe za silicon komanso zida zamakina.

Zolemba

1. Mukayika maziko a ceramic sensor, ndikofunikira kuyang'ana pa kuyimitsidwa koyimitsidwa. Kapangidwe kake kayenera kukhala ndi mphete yokakamiza yokhazikika kuti achepetse malo a sensor pachimake ndikuwonetsetsa ngakhale kugawa kupsinjika. Izi zimathandiza kupewa kusiyana kwa kupsinjika komwe kungabwere kuchokera kwa ogwira ntchito osiyanasiyana.

2. Musanayambe kuwotcherera, chitani kuyang'ana pazithunzi za sensor pad. Ngati makutidwe ndi okosijeni ali pamwamba pa pedi (kupangitsa kuti mdima), yeretsani chofufutira musanawotchere. Kukanika kutero kungapangitse kuti ma siginecha asatuluke bwino.

3. Mukawotchera mawaya otsogolera, gwiritsani ntchito tebulo lotenthetsera ndi kutentha kwa madigiri 140-150. Chitsulo cha soldering chiyenera kuyendetsedwa pafupifupi madigiri 400. Madzi opanda madzi, osachapira amatha kugwiritsidwa ntchito ngati singano yowotcherera, pomwe phala loyera la flux limalimbikitsidwa pawaya wowotcherera. Zolumikizira za solder ziyenera kukhala zosalala komanso zopanda ma burrs. Chepetsani nthawi yolumikizana pakati pa chitsulo chosungunulira ndi pad, ndipo pewani kusiya chitsulo cholumikizira pa sensor pad kwa masekondi opitilira 30.

4. Pambuyo kuwotcherera, ngati n'koyenera, kuyeretsa zotsalira flux pakati pa kuwotcherera mfundo ntchito burashi yaing'ono ndi osakaniza 0,3 mbali mtheradi Mowa ndi 0,7 mbali dera bolodi zotsukira. Sitepe iyi imathandiza kupewa kuchulukirachulukira kotsalira popanga mphamvu ya parasitic chifukwa cha chinyezi, zomwe zingakhudze kulondola kwa chizindikirocho.

5. Kupangitsa kuzindikira kwa siginecha yotulutsa pa sensa yolumikizidwa, kuwonetsetsa kuti chizindikirocho chili chokhazikika. Ngati kulumpha kwa data kukuchitika, sensa iyenera kuwotchedwanso ndikulumikizidwanso ikadutsa kuzindikira.

6. Musanayambe kuwerengera sensor pambuyo pa msonkhano, ndikofunikira kuyika zinthu zomwe zasonkhanitsidwa kupsinjika kuti muchepetse kupsinjika kwa msonkhano musanayambe kuwongolera ma siginecha.

Kawirikawiri, kupalasa njinga kwapamwamba ndi kutsika kungagwiritsidwe ntchito kuti afulumizitse kufanana kwa kupsinjika kwa chigawo pambuyo pa kukulitsa ndi kuchepetsa. Izi zitha kuchitika mwa kuyika zigawozo ku kutentha kwa -20 ℃ mpaka 80-100 ℃ kapena kutentha kwa chipinda mpaka 80-100 ℃. Nthawi yotsekera pamalo okwera komanso otsika kutentha iyenera kukhala osachepera maola 4 kuti muwonetsetse zotsatira zabwino. Ngati nthawi yotsekera ndi yochepa kwambiri, ntchitoyo idzasokonezedwa. The yeniyeni ndondomeko kutentha ndi kutchinjiriza nthawi angadziŵike kudzera kuyesera.

7. Pewani kukanda diaphragm kuti muteteze kuwonongeka kwa dera lamkati la ceramic sensor core, zomwe zingayambitse ntchito yosakhazikika.

8. Samalani pokweza kuti mupewe zovuta zilizonse zamakina zomwe zingayambitse kusagwira bwino ntchito kwa sensa core.

Chonde dziwani kuti malingaliro omwe ali pamwambapa amsonkhano wa sensa ya ceramic ndi okhudzana ndi momwe kampani yathu ikuyendera ndipo sangakhale ngati miyezo yopangira makasitomala.
