Lefoo I-Flat Film Pressure

I-silicon wafer enhle kakhulu, I-wheatstone-bhuloho kanye ne-diaphragm yokuzwela ingcindezi kuvalwa endlini yensimbi egcwele i-glycerine noma i-silil Ikhone ukufaka izinto zangaphakathi zenzwa. Izinzwa ze-diaphragm zizwela kakhulu ekushintsheni kwengcindezi esheshayo. - zivame ukusetshenziswa ezindaweni ezonakalisayo kakhulu noma ngezimo zokucindezela ngokweqile.

I-Lefoo Sensor Selection Criteria, Inzwa enhle yengcindezi eyisicaba kufanele ibe nenzuzo engezani

1. Ukubekwa uphawu okuhle, okutholakala ku-viscous medium futhi kulula ukuhlanza amabala asele.

2. Ukunemba kokulinganisa okuphakeme, ukuzinza okuhle,

3. usayizi omncane nokufakwa okulula.

4. ukusebenza okubiza kakhulu.

E-LefooUmkhiqizi wokudlulisa ingcindezi,Inzwa yengcindezi iyakwazi ukunikeza ukufundwa okunembile futhi okuqondile kwesilawuli ukulawula insimbi ye-elekthronikhi ukuvimbela ukuchichima noma ukugwema ingendo ukulimala, okuhle ngamandla ngempumelelo futhi kufeza ukusebenza kwesikhathi eside, noma kunjalo, ezinye izici zithonya ukufaneleka kwezinzwa zengcindezi eyisicaba: izici zemidiya elilinganisiwe, izimo zemvelo, Ibanga lokucindezela, kanye nezinga lokunemba ezilinganisweni ezenziwe.

Izici zenzwa yengcindezi ye-Lefoo e-flat yemidiya elilinganisiwe

UkugcotaLefoo, Inzwa yengcindezi eyisicaba (elestic element) izovezwa kwabezindaba ezisetshenziswa enqubweni yokulinganisa, ngakho-ke ama-diaphragms wensimbi amelana nokugqwala noma i-foil afanele ezindaweni ezinzima kakhulu. Izinto ezingasabela ngezinto zenqubo noma zokwehlisa kwemithombo yezindaba ezonakalisayo azikulungele ukusetshenziswa ezinzwani zengcindezi eyisicaba.

Izimo zemvelo zenzwa ye-Lefoo flat

Izindawo ezihlabayo, ukudlidliza eduze kwamapayipi, noma amazinga okushisa aphezulu kakhulu abalulekile ekukhethweni kwezinzwa zokucindezela ngenhloso yokuvikela amapayipi nezinsiza endaweni enzima kakhulu amaso.

Uchungechunge lwengcindezi ye-Lefoo flat

Inzwa yengcindezi ye-flat noma ama-transducers wengcindezi eyisicaba aklanywe ngomkhawulo wamabanga athile wengcindezi yemishini nezinsiza ezahlukahlukene. Ngoba imishini emikhulu neyinkimbinkimbi idinga izinzwa eziningi ezinokunemba okuphezulu, kepha imishini emincane yomphakathi ingadinga kuphela inzwa eyodwa enokunemba okujwayelekile, ukukhetha ingcindezi efanele transducer ibaluleke kakhulu kule nqubo.

Ukuzwela kwenzwa yengcindezi ye-Lefoo e-flat

Lapho inembile ingcindezi i-transducer, kuyabiza kakhulu, ngaleyo ndlela ukukhetha ama-transducers wengcindezi atholakalayo ukufinyelela ukunemba okufunwayo ngentengo efanele kakhulu kufaneleke impela. Ukuyekethisa phakathi kokunemba nesikhathi sokulinganisa nakho kubaluleke impela, akunakwenzeka ukusebenzisa izinzwa zokucindezela eziyisicaba ezithatha isikhathi esiningi ukunikeza ukufundwa okunembile kwengcindezi, Ukufundwa kwesilinganiso esiphakeme ngesikhathi esifushane sokulinganisa kuyasebenza lapho intengo iphakeme kakhulu.

Izixazululo Zokucindezela Okwengeziwe Ezikhulule

Inzwa yengcindezi ye-frijian: Izinhlelo zokufuduka zivame ukuhlangabezana namaphutha okufihliwe kanye nokuphathwa kokushisa okungasebenzi.

Inzwa yengcindezi yamanzi yokuphuza: Izinzwa zokucindezela kwamapayipi wamanzi zivame ukusetshenziselwa ukulinganiswa kwengcindezi yamapayipi wamanzi okungena emanzini okuhlanzekile ..

Izindlela Zokulinganisa Ingcindezi Yesikole Esidala

Izindlela zokulinganisa ingcindezi yesikole esidala zenziwe futhi zasetshenziswa emashumini eminyaka adlule futhi ezinye zazo zisasetshenziswa kwezinye ezinganombi, imishini yokunemba encane futhi ephansi.

1.Ukuphakama kwe-Liquid kukholamu

Ukuphakama koketshezi olunobuningi obaziwayo kusetshenziselwa ukukala ingcindezi. Usebenzisa i-equation P = ρgh, ingcindezi yegeji ingabalwa kalula. Lezi zinhlobo zamadivayisi wokulinganisa ingcindezi ngokuvamile abizwa ngokuthi ama-manometer. I-Mercury isetshenziswa lapho ufisa izilinganiso zengcindezi ephakeme hhayi ukuzwela okukhulu.

2. Ukuphazanyiswa Kwe-Elastic

Le ndlela yokulinganisa ingcindezi isuselwa kumqondo wokuthi ukuguquguquka kwento ehlaselayo kuyalingana ngqo nengcindezi elinganiswayo .. NjengeBourdon-tubes noma iBourdon Gauge.

3.Bellow gauge

Izakhi ze-Bellows zima nge-cylindrical futhi ziqukethe amafold amaningi. Bakhubaza ngokuqondisa kwe-axial (ukucindezelwa noma ukunwetshwa) ngezinguquko kwengcindezi. Ama-Bellows angasetshenziswa kuphela ekucindezelweni okuphansi ngokunemba okuphansi

Uhlobo lwe-Mechanical Strain

Izindlela zikagesi ezisetshenziselwa ukulinganisa ingcindezi zisebenzisa umqondo wokuthi izinguquko zobukhulu kucingo zithinta ukumelana kukagesi kumqhubi. Lawa madivayisi asebenzisa ushintsho ekumelaneni kocingo abizwa ngokuthi ama-starin gauges.

Izinhlobo zokucindezela zenzwa yengcindezi ye-lefoo flat

Ingcindezi ichazwa njengamandla endaweni ngayinye yeyunithi futhi isemayunithi yokubala ye-psi, Pa, Kpa, neBar. Uhlobo oluthathu lwengcindezi yesethenjwa lusetshenziswa ezimbonini zokulinganisa ingcindezi.

Ingcindezi ephelele - I-Pressure elinganiswe endaweni yengcindezi ye-vacuum zero, ingcindezi ye-athomuspheric kanye nengcindezi ye-gauge.

Ingcindezi ye-Gauge - Ingcindezi ilinganiswa esimweni esizungezile. Ingcindezi ephelele isusa ingcindezi yomkhathi.

Isilinganiso sokucindezela okuhlukile - isilinganiso sokucindezela ngokususelwa kwabezindaba ezifanayo noma esikhungweni esifanayo ezikhundleni ezimbili.

Ukusetshenziswa kwenzwa ye-Lefoo flat

Izinzwa zokucindezela eziphansi zisetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana ne-petrochemical, inki yokuhlanza amanzi, upende, imikhiqizo yodaka kanye neyobisi enethuba elithile lokulinganisa i-viscous.
