Lefoo Umthumeli Wokucindezela Wohlobo Olujwayelekile

Izinhlobo Zokulinganisa Ingcindezi kanye Nokusetshenziswa Kwazo

Ukuze kuhlangatshezwe izidingo eziningi ezahlukene, abakhiqizi benza izinhlobo eziningi zamadivayisi okulinganisa ingcindezi. Izibonelo zalokhu zihlanganisa ingcindezi yamanzi, ingcindezi yomoya, igesi yezokwelapha, ingcindezi kawoyela, izinga lokushisa, ingcindezi yegesi, ingcindezi kaphethiloli, ingcindezi ehlukile, nengcindezi ye-vacuum. Eminye imisebenzi yalezi zinsiza isobala kakhulu kuneminye.

I-Transducer Yengcindezi Ihlukaniswa Ngento Eyilinganisayo

I-transducer yengcindezi yamanzi (ngokwemvelo) iqapha ingcindezi yanoma yiluphi uhlelo olusekelwe emanzini. Ngokuvamile, zitholakala zinamathiselwe emathangini, lapho ziqapha ingcindezi yamanzi angaphakathi.

I-transmitter yengcindezi yegesi ilinganisa futhi ikhombise ingcindezi yegesi. Zitholakala kakhulu ezimbonini nasezindaweni zokukhiqiza, lapho zilandelela izinga lokugeleza kwegesi yemvelo enengcindezi ephezulu nephansi kanye nezinhlelo ezisekelwe ku-propane phakathiumenzi we-transmitter yengcindeziAma-gauge engcindezi kaphethiloli nawo ahlola amazinga engcindezi yegesi, kodwa akwenza lokhu ngokwesimo sezimoto. Alinganisa futhi akhombise ukutholakala kukaphethiloli, noma inani legesi, elisele ethangini lemoto.

Izinzwa zengcindezi yomoya zilinganisa ingcindezi yomoya emishini esebenza ngomoya.

Ama-transducer engcindezi kawoyela alinganisa ingcindezi kawoyela ojikelezayo ohlelweni lokugcoba.

I-Transmitter Ihlukaniswa Ngezimo Ezithile Eziklanyelwe Zona

Ama-gauge engcindezi ye-vacuum alinganisa futhi akhombise ingcindezi engaphakathi kwemikhumbi noma amasistimu acwiliswe endaweni engaphansi komkhathi noma ye-vacuum. Izindawo ze-vacuum zisetshenziswa kakhulu ukudala amazinga okushisa abandayo.

Izinzwa zengcindezi ye-seal gauge zenziwe ngokuqondile ukumisa nokugwema ukuvuza okungenzeka. Ngenxa yalokho, ziklanywe ngokufakwa kwe-diaphragm seal isolator. Iningi lemisebenzi yazo litholakala ezimbonini zezinqubo, ezemithi, zamakhemikhali, ze-petrochemical, kanye nezokukhucululwa kwendle.

Amanye ama-transmitter engcindezi angase aklanyelwe ukulinganisa ngokuqondile izinto ezigelezayo ngesivinini esiphakeme ngokwedlulele noma ngesivinini esiphansi ngokwedlulele. Ama-gauge engcindezi ephezulu abalulekile ekukhiqizeni nasezimbonini zokusebenzisa ngobaLefooI-China ehamba phambiliumenzi we-transmitter yengcindeziikakhulukazi lezo ezihlobene nobuchwepheshe be-hydraulic enengcindezi ephezulu (isib. ukudilizwa ngamanzi, amaphampu okuqhunyiswa ngamanzi, nemishini yokusika amanzi). Ama-gauge engcindezi ephansi anembe ngokwedlulele futhi azwelayo, ngokuvamile alinganisa izingcindezi eziphakathi kwe-PSI eyishumi neshumi nanhlanu. Abaluleke kakhulu ezinhlelweni ezenzeka ezindaweni ezinokushintshashintsha kwengcindezi kaningi.

Ukuhlukaniswa Ngamazinga Ahlukene Engcindezi

Kuze kube manje, kuxoxwe kuphela ngama-transmitter engcindezi asebenza ngokubhekisela engcindezini ye-gauge. I-transmitter yengcindezi ekala ingcindezi ye-gauge isebenzisa ingcindezi yomkhathi ezungezile njengendinganiso ekala ngayo. Nokho, le akuyona ukuphela kwendlela i-transmitter yengcindezi engasebenza ngayo. Okuhlukile okuyinhloko kulandela ngezansi.

I-Transmitter Yengcindezi Ihlukaniswa Ngezinhlobo Zokusetshenziswa

Enye indlela yokubheka ukuhlukaniswa kwe-gauge ukugxila ekusetshenzisweni okuqondile i-gauge esetshenziselwa kona. Ukunikeza isibonelo esisodwa nje, ama-transmitter engcindezi awuhlobo olukhethekile lwe-gauge yokuhlola ingcindezi embonini ye-HVAC. Amadivayisi amaningi engcindezi aklanyelwe ukusetshenziswa nohlobo oluthile lomkhiqizo.

Izinhlobo Zezinzwa Zengcindezi

Izinzwa zengcindezi ezisetshenziswa kakhulu ezimbonini zokukhiqiza zanamuhla izinzwa zengcindezi ze-piezoresistive. Futhi iyunithi ebiza kakhulu enzwayi i-diaphragm ye-piezoresistive – eyakhiwe kakhulu ngamakristalu e-Silicon kanye nezitsha ezithile ze-Ceramic. Amakristalu e-piezoelectric akhiqiza ukushajwa kagesi lapho evezwa ingcindezi yemishini, elingana namandla/ingcindezi esetshenzisiwe. I-conditioner yesignali iguqula isignali yokushajwa ibe isignali ye-voltage. Ama-ceramics asetshenziselwa ukukala ingcindezi yegesi noma uketshezi olonakalisayo oluqinile.

Izinzwa zengcindezi ze-piezoresistive zilungele ukulinganisa izingcindezi eziguquguqukayo. Ukushaya okuncane kwengcindezi (njengama-Compressor Aerodynamic) kanye nezingcindezi ezi-quasi-static, izinzwa zengcindezi ze-piezoresistive ziyatholakala ukukala ngesikhathi esifushane emazingeni okushisa aphezulu kakhulu noma aphansi.

Izinzwa zengcindezi ze-strain. Iyunithi eyinhloko amafilimu amancane e-polymer asontekayo (i-foil).

Izimpawu zengcindezi ezikhiqizwa yi-strain foil zibuthaka kakhulu futhi zidinga i-Wheatstone bridge ukuze zikhuliswe futhi zilungiselele idatha yokulinganisa. I-strain type foil iyimpahla enezindleko eziphansi kakhulu ezimbonini eziningi zokukhiqiza. I-Wheatstone bridge inemigqa engu-4 futhi ngamunye unomphumela futhi yonke imiphumela izobalwa ukunembisa idatha yokulinganisa.

Ukulinganisa ingcindezi ye-strain akutholakali ngezingcindezi eziphezulu kwenzeka nge-frequency ephezulu ngesikhathi esifushane. Futhi idatha yokulinganisa ithinteka kalula ngezinga lokushisa. Ngakho-ke izinzwa ze-strain azizona izinketho ezinhle ezimbonini zanamuhla ezifana nezindiza, imikhumbi, izimoto, nezimboni zezimayini...

Izinzwa zengcindezi ze-capacitive zisebenzisa umgodi wengcindezi ne-foil (i-diaphragm) ukukhiqiza i-capacitor eguquguqukayo. I-foil iba nokushintsha kwesimo lapho ingcindezi isetshenziswa futhi i-capacitance yehla ngokufanele. I-capacitor iwuhlobo lwebhethri oluhlinzeka amandla kagesi ngokwamavelu engcindezi. Ngakho-ke lokhu kushintsha komthamo kungalinganiswa ngogesi futhi kudluliswe kube izimpawu. Lezi zinzwa zikhawulelwe ezingcindezini eziphansi. Izinzwa zengcindezi ze-capacitive zingabizi ngentengo kodwa zisebenzisa ugesi omningi kunezinzwa zengcindezi ze-piezoresistive. Izinzwa zengcindezi ze-capacitive zisetshenziswa ezinhlelweni zokuqapha imibhede, amateki ahlakaniphile, ama-switch engcindezi yomnyango.

Izinzwa Zengcindezi Ngokwezilinganiso

Inzwa Yengcindezi Ephelele

Ingcindezi ephelele iyisamba sengcindezi ye-gauge nengcindezi yomkhathi ezungezile, ikala ingcindezi engenayo evela endaweni ngokubhekisela engcindezini ye-vacuum enguziro. Ingcindezi ephelele ingcindezi yangempela ezinhlelweni ezivaliwe noma ezitsheni ezivaliwe emkhathini endaweni ethile ephakeme. Ingcindezi ephelele iyinkomba eyinhloko ezimbonini zokudla neziphuzo, ezimbonini zezinto, ezimbonini zokuthutha. Izinzwa zengcindezi ephelele ngokuvamile zisetshenziswa ocwaningweni nasezinhlelweni zesayensi.

I-Transducer Yengcindezi Ehlukile

Ukulinganisa ingcindezi ehlukile kusekelwe ezingcindezini ezimbili ezizimele kodwa ezikhona ngokuqhathaniswa. Ama-transducer engcindezi ane-diaphragm lapho uhlangothi olulodwa lukala endaweni yokuqala kanti olunye uhlangothi lukala enye indawo. Izingcindezi zibizwa ngokuthi ingcindezi ephezulu nengcindezi ephansi. Ukusetshenziswa kwama-transducer engcindezi ehlukile banzi kakhulu. Njengezimboni zokucubungula amanzi, ukuhlanza indle, ama-boiler oketshezi, izinhlelo ze-HVAC

Izinzwa Zengcindezi Ye-Gauge

Ingcindezi ye-gauge yingcindezi ephakathi kwengcindezi ephelele (ingcindezi ephelele) nengcindezi yomkhathi. (Ingcindezi ye-gauge = ingcindezi ephelele - ingcindezi yomkhathi), Ukulinganisa ingcindezi ye-gauge kusetshenziswa ethayini lemoto, ukuthuthwa kwegesi yemvelo, isilinda se-hydrogen, imikhiqizo ehlobene nezicishamazwi. Kuphinde kusetshenziswe ezinhlelweni zokuphakela imfuyo.
