Masensa opanikizika ndi gawo lofunikira m'mafakitale ambiri, zomwe zimapereka kuthekera koyezera molondola komanso modalirika kukakamiza pamagwiritsidwe osiyanasiyana.Mtundu umodzi wa sensor yapaintaneti yomwe yatchuka kwambiri m'zaka zaposachedwa ndi kachipangizo kakang'ono kakang'ono ka galasi, kamene kanapangidwa koyamba ndi California Institute of Technology mu 1965.
Kachipangizo kakang'ono ka galasi kakang'ono kamene kamasungunuka kamakhala ndi galasi lotentha kwambiri lomwe limayikidwa kumbuyo kwa 17-4PH chitsulo chochepa cha carbon, chomwe chili ndi chitsulo chosapanga dzimbiri cha 17-4PH.Kapangidwe kameneka kamapangitsa kuti pakhale kuchulukirachulukira komanso kukana kugwedezeka kwadzidzidzi.Kuphatikiza apo, imatha kuyeza zamadzimadzi zomwe zimakhala ndi zonyansa zochepa popanda kufunikira kwamafuta kapena ma diaphragms odzipatula.Kumanga zitsulo zosapanga dzimbiri kumathetsa kufunika kwa mphete za O, kuchepetsa chiopsezo cha kutulutsa kutentha.Sensa imatha kuyeza mpaka 600MPa (6000 bar) pansi pamikhalidwe yopanikizika kwambiri yokhala ndi zinthu zolondola kwambiri za 0.075%.
Komabe, kuyeza timagulu tating'ono tating'ono tating'ono tating'onoting'onoting'onoting'onoting'ono kumatha kukhala kovuta, ndipo nthawi zambiri kumangogwiritsidwa ntchito kuyeza milingo yopitilira 500 kPa.M'magawo omwe ma voliyumu apamwamba komanso kuyeza kolondola kwambiri ndikofunikira, sensa imatha m'malo mwa ma sensor achikhalidwe omwe amasiyanitsidwa ndi silicon ndikuchita bwino kwambiri.
MEMS (Micro-Electro-Mechanical Systems) teknoloji yogwiritsira ntchito makina osindikizira ndi mtundu wina wa sensa yomwe yatchuka kwambiri m'zaka zaposachedwa.Masensa awa amapangidwa pogwiritsa ntchito ma silicon strain gauges ang'onoang'ono / nanometer, omwe amapereka kukhudzika kwakukulu, magwiridwe antchito, kupanga batch yodalirika, komanso kubwereza kwabwino.
Galasi yosungunuka ya galasi imagwiritsa ntchito ukadaulo wapamwamba pomwe silicon strain gauge imayikidwa pa 17-4PH chitsulo chosapanga dzimbiri chotanuka galasi litasungunuka kutentha pamwamba pa 500 ℃.Pamene theelastic bodyundergoescompression deformation, imapanga chizindikiro chamagetsi chomwe chimakulitsidwa ndi chiwongolero cha digito chokulitsa ndi microprocessor.The linanena bungwe chizindikiro ndiye pansi wanzeru kutentha chipukuta misozi ntchito digito mapulogalamu.Panthawi yopanga zoyeretsera, magawowa amawunikidwa mosamalitsa kuti asatengeke ndi kutentha, chinyezi, komanso kutopa kwamakina.Sensa imakhala ndi kuyankha kwafupipafupi komanso kutentha kwakukulu kogwira ntchito, kuonetsetsa kuti kukhazikika kwa nthawi yayitali m'madera ovuta a mafakitale.
Dera lanzeru lolipirira kutentha limagawaniza kusintha kwa kutentha m'magawo angapo, ndipo malo a zero ndi mtengo wamalipiro pagawo lililonse zimalembedwa mugawo lamalipiro.Pogwiritsa ntchito, mfundozi zimalembedwa mu njira yotulutsa analogi yomwe imakhudzidwa ndi kutentha, ndi kutentha kulikonse kumakhala "kutentha kwa kutentha" kwa transmitter.Dera la digito la sensayo limapangidwa mosamala kuti lizitha kuthana ndi zinthu monga pafupipafupi, kusokoneza ma electromagnetic, ndi magetsi othamanga, okhala ndi mphamvu zotsutsana ndi kusokoneza, kuchuluka kwa magetsi, komanso chitetezo cha polarity.
Chipinda chopondereza cha sensa ya galasi yosungunuka imapangidwa ndi chitsulo chosapanga dzimbiri cha 17-4PH, chopanda mphete za O, ma welds, kapena kutayikira.Sensa ili ndi mphamvu yodzaza ndi 300% FS ndi kulephera kwa 500% FS, ndikupangitsa kuti ikhale yabwino kwa ntchito zolemetsa kwambiri.Kuti muteteze ku kugwedezeka kwadzidzidzi komwe kungathe kuchitika m'makina a hydraulic, sensa imakhala ndi chipangizo chodzitetezera chokhazikika.Amagwiritsidwa ntchito kwambiri m'mafakitale olemera monga makina a asengineering, makina opanga makina, zitsulo, makampani opanga mankhwala, mafakitale amagetsi, mpweya woyeretsa kwambiri, kuyeza kwa hydrogen, ndi makina aulimi.
