Lefoo Isidlulisi Sokucindezela Kohlobo Jikelele

Izinhlobo Zokulinganisa Ukucindezela Nokusebenza

Ukwamukela izinhlelo eziningi ezahlukahlukene, abakhiqizi benza izinhlobo eziningi zamadivayisi zokulinganisa ingcindezi. Izibonelo zalokhu zifaka ingcindezi yamanzi, ingcindezi yomoya, igesi yezokwelapha, ingcindezi kawoyela, izinga lokushisa, ingcindezi yegesi, ingcindezi kaphethiloli, ingcindezi yokuhlukanisa, nengcindezi ye-vacuum. Okunye kokusetshenziswa kwalawa madivayisi kusobala kakhulu kunezinye.

I-transducer yengcindezi ihlukaniswe yi-Substance Abalinganisa

I-transducer yengcindezi yamanzi (ngokwemvelo) iqapha ingcindezi yanoma yiluphi uhlelo olususelwa emanzini. Ngokuvamile, zitholakala zinamathele emathangini, lapho ziqapha khona ingcindezi yamanzi ngaphakathi.

Izinyathelo zokudlulisa ingcindezi yegesi futhi zikhombisa ingcindezi yegesi. Zivame kakhulu emafektri nasezikhungweni zokukhiqiza, lapho begcina khona ukulandela izinga lokugeleza lezinhlelo zombili igesi yemvelo ephezulu nephansi kanye nezinhlelo ezisuselwa ku-propane ku-Umkhiqizi wokudlulisa ingcindezi. Amageji wengcindezi kafuthi nawo ahlola amazinga omfutho wegesi, kepha akwenza kanjalo ngomongo wezimoto. Balinganisa futhi bakhombise ukunikezwa kukaphethiloli, noma inani legesi, elishiywe ethangini lemoto.

Izinzwa zokucindezela komoya zikala ingcindezi ye-pneumatic emishinini esebenza ngomoya.

Ama-transducers wengcindezi kawoyela alinganisa ingcindezi kawoyela ojikeleza ohlelweni lokuthambisa.

Umthumeli Uhlukaniswe Izimo Ezithile Ziklanyelwe

Isilinganiso sezingcindezi ze-vacuum futhi sibonisa ingcindezi ngaphakathi kwemikhumbi noma izinhlelo ezicwiliswe emkhathini ongaphansi komhlaba noma imvelo ye-vacuum. Izindawo ze-vacuum zisetshenziselwa ikakhulukazi ukudala amazinga okushisa abandayo.

Izinzwa zezingcindezi ze-gauge zenziwa ngqo ukumisa nokugwema ukuvuza okungaba khona. Ngakho-ke, zaklanywa ngokufakwa kwe-diaphragm seal isolator. Iningi lezicelo zabo zitholakala kule nqubo, ezemithi, zamakhemikhali, ezemvelo, nezokukhuculula.

Ezinye izidlulisi zokucindezela zingaklanywa ukukala ngqo izinto ezigeleza ngama-velocities aphezulu kakhulu noma aphansi ngokukhethekile ijubane. Amageji anengcindezi ephezulu abalulekile ekukhiqizeni nasezimboniLefoo, IChina iholaUmkhiqizi wokudlulisa ingcindezi, Ikakhulukazi lezo ezihlobene nobuchwepheshe be-hydraulic ephezulu (e. g. Ukudilizwa kwe-hydro, amaphampu okuqhuma e-hydro, nemishini yokusika yamanzi. Amageji anengcindezi ephansi anembile ngokweqile futhi abucayi, ngokuvamile alinganisa ingcindezi phakathi kwe-PSI yeshumi neshumi nanhlanu. Kubalulekile ikakhulukazi ezinhlelweni ezenzeka ezindaweni ezinokuguquguquka kwengcindezi njalo.

Ukuhlukaniswa Ngezindinganiso Ezihlukile Zengcindezi

Kuze kube manje, kuxoxwe ngakho kuphela izidlulisi zokucindezela ezisebenza ngokubhekisele kwengcindezi yegaji. Isidlulisi sokucindezela esilinganisa ingcindezi yegaji sisebenzisa ingcindezi esemkhathini ezungezile njengezinga elilinganisa ngalo. Kodwa-ke, le akuyona ukuphela kwendlela yokudlulisa ingcindezi ukusebenza. Okuhlukile okuyinhloko kulandela ngezansi.

Ukudlulisa Ingcindezi Kuhlukaniswe Izinhlobo Zokusebenza

Kodwa enye indlela yokusondela ukuhlukaniswa kwegeji kugxile kuhlelo oluthile olusetshenziselwa igeji. Ukunikeza isibonelo esisodwa kuphela, izidlulisi zokucindezela ziwuhlobo olukhethekile lwegeji yokuhlola ingcindezi ngaphakathi kwemboni ye-HVAC. Amadivayisi amaningi okucindezela enzelwe ukusetshenziswa ngohlobo oluthile lomkhiqizo.

Izinhlobo Zezingcindezi

Izinzwa zokucindezela ezisetshenziswa kakhulu ezimbonini zesimanje zokukhiqiza yizinzwa zokucindezela ze-piezoresistive. Futhi iyunithi ebiza kakhulu enzwa yi-piezoresistive diaphragm - ikakhulukazi eyenziwe ngama-Silicon Crystals ne-Ceramic ethile amas. Amakristalu e-Piezoelectric akhiqiza inkokhiso kagesi lapho evezwa ekucindezelekeni kwemishini, okulingana namandla / ingcindezi esetshenzisiwe. Isimo sesiginali siguqula isignali yokushaja ibe yisiginali yama-voltage. Ama-ceramics asetshenziselwa ukukala ingcindezi yegesi enamandla noma uketshezi.

Izinzwa zokucindezela ze-Piezoresistive zilungele ukukala izingcindezi ezinamandla. Ukuqhuma kwengcindezi encane (njenge-compressors Aerodynamic) kanye nezingcindezi ze-quasi-static, Izinzwa zokucindezela ze-Piezoresistive ziyatholakala ukukala ngesikhathi esifushane emazingeni okushisa aphezulu kakhulu noma aphansi.

Izinzwa zokucindezela. Iyunithi eliyinhloko amafilimu e-polymer amancane (foil).

Amasiginali wokucindezela akhiqizwa kusuka ku-stoin foil abuthakathaka kakhulu futhi adinga ibhuloho le-Wheatstone ukukhulisa nokulungisa idatha yokulingana .. I-foil yohlobo lohlobo lomzimba iyizinto ezindleko eziphansi kakhulu ezimbonini eziningi zokukhiqiza. Ibhuloho le-Wheatstone linemigqa emi-4 futhi ngamunye wazo unomphumela futhi yonke imiphumela izobalwa ukuqondisa idatha yokulinganisa.

Isilinganiso sokucindezela okungatholakali kwengcindezi ephezulu senzeka ngemvamisa ephezulu ngesikhathi esifushane. Futhi imininingwane yokulinganisa ithinteka kalula ukushisa. Ngakho - ke izinzwa ze - Strain azizona izindlela ezinhle zezimboni zanamuhla ezinjengezindiza, imikhumbi, izimoto, nezimboni zezimayini......

Izinzwa zokucindezela ze-Capacitive zisebenzisa umgodi wengcindezi kanye ne-foil (i-diaphragm) ukukhiqiza i-capacitor eguquguqukayo. I-foil inokuguqulwa kwesimo lapho kusetshenziswa ingcindezi futhi i-capacience yehla ngokufanele. I-capacitor uhlobo lwebhethri elihlinzeka ngamandla kagesi ngokuya ngamanani wengcindezi. Ngakho-ke lolu shintsho kumthamo lungalinganiswa ngogesi futhi ludlulisele lube amasiginali. Lezi zinzwa zikhawulelwe ezingcindezini eziphansi. Izinzwa zokucindezela ziyintengo yezomnotho kepha ngokusetshenziswa kukagesi okuphezulu kunezinzwa zokucindezela kwePiezoresistive. Izinzwa zokucindezeleka ezisetshenziswa ezinhlelweni zokuqapha umbhede, ama-sneakers ahlakaniphile, ukushintshwa kwengcindezi yomnyango.

Izizwe Zokucindezela Ngokulinganisa

Umntwana Wokucindezela Okupheleleyo

Ingcindezi ephelele yisamba sengcindezi yegauge kanye nengcindezi yesimo sezulu, Ilinganisa ingcindezi yokufaka evela esiphakathi ngokubhekisele kwingcindezi ye-vacuum zero. Ingcindezi ephelele ingcindezi yangempela ezinhlelweni ezivaliwe noma iziqukathi ezivaliwe emkhathini endaweni ephakeme ethile. Ingcindezi ephelele iyinkomba eyinhloko yezimboni zokudla neziphuzo, izimboni zezinto ezibonakalayo, izimboni zezokuthutha. Izinzwa zokucindezela eziphelele zivame ukusetshenziswa ocwaningweni nasezinhlelweni zesayensi.

I-transducer yokucindezela ehluke

Ukulinganisa kwengcindezi ehlukile kususelwa kuzingcindezi ezimbili ezizimele kodwa ezikhona. Ama-transducers angcindezi ane-diaphragm ohlangothini olulodwa alinganisa phakathi nelinye uhlangothi ulinganisa enye indlela. Izingcindezi zibhekiswa ngengcindezi ephezulu nengcindezi ephansi. Ukusetshenziswa kwama-transducers wengcindezi ehlukile kukhulu kakhulu. Njengezimboni zokucubungula amanzi, ukwelashwa kwendle, ama-boilers othinzi, izicelo ze-HVAC

Izinzwa Zokucindezela zeGauge

Ingcindezi yegage ingcindezi phakathi kwengcindezi ephelele (ingcindezi ephelele) nengcindezi yomkhathi. (Ingcindezi ye-Gauge = ingcindezi ephelele- ingcindezi yomkhathi), Isilinganiso sokucindezela kwegauge sisetshenziswa ethayini lemoto. e, Ukuthuthwa kwegesi yemvelo, i-hydrogen silinda, imikhiqizo ehlobene nomcimi womlilo. Okunye kusetshenziswa ezinhlelweni zokudla imfuyo.
