Lefoo Isidluliseli Sokucindezela Okunemba Okuphakeme

Isidlulisi sokucindezela okunemba okuphezulu sisebenzisa i-diaphragm yohlobo lwe-silicon efakwe ezindlini zensimbi egcwele uwoyela. futhi izakhiwo eziphindaphindekayo neziphansi ze-silicon zixhashazwa ngomehluko wokujwayelekile kwedijithali yokuhlinzeka ngokunemba okulungisiwe kwe-me. imiphumela yokuhlola ezungeze uhla lokushisa lokuzungeza. Ibhuloho eline le-Wheatstone lisakazwa libe yi-silicon wafer bese lifakwa imishini emincane kumazinga okufuna ukukhiqiza ingcindezi inzwa.

Ukusetshenziswa kwe-LIFOO yokunemba okuphezulu kokudluliselwa kwengcindezi

E-Lefoo, enye yesiphezuluAbahlinzeki abaphambi kwengcindezi, Ngokunemba okuphezulu nokuzinza kwesikhathi eside, lezi zingcindezi eziphakeme zokunemba kanye nezidlulisi zikulungele ikakhulukazi ukusebenza kokugeleza noma kunoma iyiphi indawo lapho ukulinganisa ukuqina okuphakeme kuyadingeka. Zisetshenziswa njengamadivayisi wokulinganisa ingcindezi ezimbonini zesimanje ezizenzakalelayo zokusebenza kahle kwamandla nokuphila okude kwemishini. Lezi zici ziyenza ibe yithuluzi elibalulekile ku-metrology, i-hydrology, i- Oceanography, nezimboni.

Ama-calibrar

Imigudu yomoya

Noma emagumbini okucindezela

Isidlulisi sokucindezela okunemba okuphezulu kwe-Lefoo sinezinhlelo zokusebenza njengoba ngezansi

• Ubuchwepheshe bokuhlola

• Ubuchwepheshe bokhalisela

• I-Geoscience / hydrology

• Ukuzwa kwengcindezi ephezulu kokunemba ekukhiqizeni imishini yokuqala (ama-OEMs)

• I-Aerospace / Amasosha

• Amalebheli nezitolo zokugcina

• Izinhlelo zokusebenza nokususa

• Imihubhe yomoya

• Ukuqashwa kwezingazi

• I-OEM / Inhlolo

• Izindizayo

Izici ziba nomthelela ekunembeni kokudluliselwa kwengcindezi ephezulu kokunemba okuphezulu kokudlulisela

UkugcotaLefoo, Kunezici eziningi ezithonya ekukhethweni kwedivayisi yokuzwa kuhlelo oluthile.Inzwa yengcindezi yegage, Okuphelele noma okuhlukile, i-transducer noma i-transducer, ibanga lokulinganisa, isitayela / isayizi, futhi izilinganiso eziphelele ezifana nengcindezi yokuqhuma ziphakathi kwezibaluleke kakhulu.

Izici ezithinta ukunemba kwengcindezi yokunemba okuphezulu kokudluliselwa kwengcindezi

Ukukhetha okufanele kungase kuqondiswe ngokucabangela izici ezithinta ukunemba. Izici ezinkulu ze-transducers zokucindezela okuphezulu ezithonya ukunemba ngama-coefficients okushisa, i-hyseris yokushisa, ingcindezi hysteresis, nokungabikho komugqa. Ama-coefficients wokushisa asebenzayo afaka izinguquko ezihlobene nokushisa ku-zero offset, ukuzwela, kanye nesikhathi sokulinganisa.

Iphutha lokushisa eliphezu kuka-85 ° C wama-transmitter wengcindezi ephakeme

Isidlulisi sokucindezela okuphezulu kwe-LFT2010 sokusebenza kokushisa okuphezulu kwe-85 ° C sizodala umonakalo unomphela ekunembeni. Izinga lokushisa elifanele lokusebenza lingaphakathi kwebanga elingu -10 ° C kuya ku-70 ° C. Isibonelo, kunenzwa ejwayelekile yengcindezi yokunemba ephezulu emakethe enokunemba okungu-0.5% (hhayi imikhiqizo ye-LEFOO). Ukunemba kwe-0.5% FS akufaki iphutha lokushisa elihlala unomphela elingu-0.02%X3 = 0.06% degree ngomzuzwana. ICelsius. Izinga lokushisa eliphakeme kakhulu lizolonakalisa ukunemba nenzwa ngemizuzwana.

Ukunciphisa lephutha lokushisa elengeziwe futhi ucabange ukuthi unekhono lokulinganisa inzwa lapho izinga lokushisa liphakathi kuka-80 no-90 ° C,Ukulawulwa kwengcindezi ye-LEFOOUphatha iphutha elivela egumbini liye ku-90℃ njengokushintshwa kokulinganisa ngoba unentshisekelo yokuthuthukisa ukusebenza phakathi kuka-80 no-90 ° C .. Ngakho-ke indlela elula yokunciphisa iphutha lokushisa ukubheka isignali yokukhipha ku-zero kanye nengcindezi ephelele lapho izinga lokushisa liseku maphakathi nephuzu 85 ° C. Uma ungakwazi ukusetha ingcindezi egcwele, indlela elula kakhulu ukubheka i-zero shift ku-85 ° C ngoba iningi lephutha elishisayo livame ukunikelwa yi-therma zero shift.

I-Lefoo Custom Okunemba Okuphakeme

I-LEFOO inikeza i-ODMOkunezinzo ezinhle kakhulu zesikhathi eside, ukulingana, ukuphindaphindeka. I-LEFOO nayo ingahlinzeka ngamabhange amiselwe ngokwezifiso ama-transducers ezinqoleni zokuhlola, ama-rack, noma amabhentshi ukufeza isidingo esithile sokuguquguquka ebangeni lengcindezi kanye nenxephezelo yokushisa.

Izinhlelo zokwezifiso zingaqukatha izinto ezahlukahlukene kufaka phakathi isoftware yokulawula, abalawuli bengcindezi, ukushintshwa kwengcindezi kanye nanoma yimiphi imishini egumbisiwe ekhasimende edingekayo.
