Ukusuka kwiintambo zokuqhuba iirobhothi ukuya kwiibhanti zokuhambisa kwiinkqubo zokubonelela ukuya kwiinqaba ze-wind turbine, ukuvakalelwa kwesikhundla ngumsebenzi obalulekileyo kuluhlu olubanzi lwezicelo.Inokuthatha iindlela ezininzi, ezibandakanya i-linear, i-rotary, i-angular, i-absolute, i-incremental, i-contact kunye ne-non-contact sensors.Izinzwa ezikhethekileyo ziye zaphuhliswa kwi-pontetechnical positiones ezinokuthi ziphuhliswe kwi-potetechnication se-sensometrics ezinokuthi zibonelele. i-ductive, i-eddy yangoku, i-capacitive, i-magnetostrictive, i-Hall effect, i-fiber optic, i-optical kunye ne-ultrasonic.
Le FAQ ibonelela ngentshayelelo emfutshane kwiindlela ezahlukeneyo zokuva indawo, emva koko iphonononge uluhlu lwetekhnoloji abaqulunqi banokukhetha kubo xa bephumeza isisombululo sendawo.
I-Potentiometric sensor sensors zizixhobo ezisekelwe kwi-resistance ezidibanisa umzila ochanekileyo odibeneyo kunye ne-wiper edityaniswe kwinto ekufuneka isikhundla sayo sivakalelwe.Intshukumo yento ihambisa i-wiper ecaleni komzila.Isikhundla sento silinganiswa ngokusebenzisa inethiwekhi ye-voltage divider eyakhiwe ngama-rails kunye nee-wipers ukulinganisa i-linear okanye i-rotational motion kunye ne-voltage ehleliweyo ye-DC (Umfanekiso , kodwa i-sensor ye-pote ephantsi inexabiso eliphantsi, kodwa i-sensor ye-pote ephantsi i-Pote ine-repeability ephantsi).
I-inductive position sensors zisebenzisa utshintsho kwiipropati ze-magnetic field ezifakwe kwi-coil ye-sensor.Kuxhomekeke kwi-architecture yabo, banokulinganisa izikhundla zomgca okanye ezijikelezayo.I-Linear Variable Differential Transformer (LVDT) i-sensor ye-position sensors isebenzisa iikhoyili ezintathu eziboshwe kwi-tube engenanto;Ikhoyili ephambili kunye neekhoyili ezimbini zesibini.Iikhoyili zixhunyiwe kuchungechunge, kwaye ubudlelwane besigaba sesibini sesibini yi-180 ° ngaphandle kwesigaba ngokubhekiselele kwi-coil yokuqala.I-coil ye-ferromagnetic ebizwa ngokuba yi-armature ifakwe ngaphakathi kwi-tube kwaye ixhunywe kwinto kwindawo ekulinganiswa kuyo.I-voltage yokuvuselela isetyenziswe kwi-coil yokuqala kunye ne-electromagnetic force force (i-EMF) i-coil ye-electromagnetic force. indawo ye-armature kunye nento eqhotyoshelwe kuyo inokumiselwa.I-voltage ejikelezayo ye-voltage differential transformer (RVDT) isebenzisa ubuchule obufanayo ukulandelela indawo ejikelezayo.I-LVDT kunye ne-RVDT izinzwa zinika ukuchaneka okulungileyo, umgca, isisombululo kunye novelwano oluphezulu.Azikhubeki kwaye zinokutywinwa ukuze zisetyenziswe kwiindawo ezinzima.
Abenzi boluvo bangoku be-Eddy basebenza ngezinto eziqhubayo.Imisinga ye-Eddy yimisinga enyanzelwayo eyenzeka kwizinto eziqhubayo kubukho bomhlaba oguqukayo wemagnethi.Le misinga iqukuqela kwiluphu evaliweyo kwaye ivelise indawo yesibini yemagnethi.Izinzwa zangoku ze-Eddy zibandakanya iikhoyili kunye neesekethe zomgca. eveliswa yimisinga eddy, echaphazela i-coil impedance.Njengoko into isondela ngakumbi kwikhoyili, ilahleko ye-eddy yangoku iyanda kwaye i-voltage ye-oscillating iba yincinci (Figure 2) .I-voltage ye-oscillating ilungiswa kwaye iqhutywe yi-linearizer yesekethe ukuvelisa i-DC ye-linear ngokuhambelana nomgama wento.
Izixhobo zangoku ze-Eddy zihexa, izixhobo ezingaqhagamshelwanga ziqhele ukusetyenziswa njengezixhobo zokubona kufutshane. Ziyi-omnidirectional kwaye zinokumisela umgama onxulumene nento, kodwa hayi indlela okanye umgama opheleleyo ukuya kwinto.
Njengoko igama libonisa, i-capacitive position sensors ilinganisa utshintsho kwi-capacitance ukumisela indawo yento ebonwayo.Ezi zinzwa ezingadibaniyo zingasetyenziselwa ukulinganisa indawo yomgca okanye yokujikeleza.Ziquka iipleyiti ezimbini ezahlulwe yi-dielectric material kwaye zisebenzisa enye yeendlela ezimbini zokubona indawo yento:

I-Magnetostriction yipropathi yezixhobo ze-ferromagnetic ezibangela ukuba izinto zitshintshe ubungakanani bayo okanye imilo xa kufakwe i-magnetic field sensor, i-magnetostriction position sensor, i-movable position magnet idityaniswe kwinto elinganiswayo.Iquka i-waveguide equkethe iingcingo ezithwala i-pulses yangoku, edityaniswe kwi-sensor ebekwe ekupheleni kwe-wave wave3se, i-Figu ithunyelwe kwi-wave pulses yangoku. ucingo olusebenzisana ne-axial magnetic field of the magnetic esisigxina (umazibuthe kwi-cylinder piston, Umfanekiso 3a) .Intsebenziswano yentsimi ibangelwa ukujija (umphumo we-Wiedemann), othintela ucingo, ukuvelisa i-acoustic pulse esasaza kunye ne-waveguide kwaye ifunyenwe yinzwa ekupheleni kwe-waveing ​​ye-wave ye-wave ye-wave ye-wave ye-wave ye-wave ye-wave ye-wave ye-3. i-pulse yangoku kunye nokufunyanwa kwe-acoustic pulse, indawo ehambelanayo yemagnethi yendawo kwaye ke into inokulinganiswa (Fig.3c).
Abenzi boluvo bendawo yemagnethi zizinto ezingadibanisiyo ezisetyenziselwa ukubona indawo enomda.Ii-Waveguides zihlala zigcinwe kwintsimbi engatyiwa okanye iityhubhu zealuminiyam, nto leyo eyenza ukuba ezi zinzwa zisetyenziswe kwindawo ezimdaka okanye ezimanzi.
Xa umqhubi obhityileyo, osicaba ubekwe kumhlaba wemagnethi, nakuphi na ukuqukuqela kwangoku kuthande ukwakha kwelinye icala le-conductor, nto leyo eyenza umahluko onokubakho obizwa ngokuba yi-voltage yeHolo.Ukuba i-voltage ekhoyo kwi-conductor ihlala ihleli, ubukhulu bombane weHolo buya kubonakalisa amandla ombane wemagnethi. Ngokulinganisa i-voltage yeHolo, indawo yento inokumiselwa.Kukho i-sensor ye-Hall-effect positions ezikhethekileyo ezinokumisela indawo kwimilinganiselo emithathu (Umfanekiso 4) .I-Hall-effect position sensors zizixhobo ezingabonakaliyo ezibonelela ngokuthembeka okuphezulu kunye nokuqonda ngokukhawuleza, kwaye zisebenza kuluhlu olubanzi lweqondo lokushisa.Zisetyenziswa kuluhlu lwabathengi, i-industrial application, i-automotive kunye neyonyango.
Kukho iintlobo ezimbini ezisisiseko ze-fiber optic sensors.Intrinsic fibre optic sensors, ifayibha isetyenziswa njenge-sensing element.Kwizinzwa zefiber optic zangaphandle, i-fiber optics idityaniswe nenye iteknoloji yesivamvo ukuhambisa umqondiso kwii-electronics ezikude ukuze zicutshungulwe.
