Ifanelekile kwiToyota yokutshintsha uxinzelelo lwenzwa 88645-60030

Itekhnoloji esetyenziswa ngababonisi bangoku ibaluleke kakhulu, kuba abenzi boluvo abahlukeneyo banokuba neempawu ezahlukeneyo kwizicelo ezahlukeneyo. Uninzi lwabenzi boluvo banokusebenza ngenxa yokuba iingcingo eziphetheyo ngoku ziya kuvelisa imimandla yamagnetic. Xa ulinganisa ngokuthe ngqo i-current in circuit, nceda usebenzise i-resistor yokufumanisa yangoku.

1. I-Hall effect-Hall effect sensor iquka i-core, i-Hall effect device kunye ne-signal conditioning circuit. I-sensor isebenza xa i-conductor yangoku idlula kwi-core magnetic egxininisa i-magnetic field ye-conductor. Izixhobo zempembelelo zeholo ezifakwe kumbindi wemagnethi kwii-engile ezichanekileyo ukuya kwindawo egxininisiweyo yemagnethi evuselela iholo kunye nomsinga oqhubekayo (kwinqwelomoya enye). Emva koko, iholo elinamandla libonakaliswe kwintsimi yamagnetic ukusuka kumbindi, kwaye umahluko onokuthi uveliswe, onokulinganiswa kwaye ukhuliswe njengomqondiso wezinga lenkqubo, njenge-4-20mA okanye ukuvalwa koqhagamshelwano.

2. I-inductive-inductive sensors isebenzisa iikhoyili apho iingcingo ezithwala ngoku zidlula. Oku kubangela ukuba umlinganiselo wangoku ukuya kwikhoyili. Oku kungenxa yommandla wemagnethi oveliswa ngumsinga oqukuqelayo. Abenzi boluvo be-inductive basetyenziselwa ukutshintshwa kwangoku. Inzwa ine-core ejikelezayo kunye ne-signal conditioner. Xa umqhubi wangoku edlula kwi-core magnetic, iya kunyuswa yintsimi yamagnetic yomqhubi. Ngenxa yokuba umsinga otshintshisayo uhlala utshintsha ukusuka kwisakhono esingalunganga ukuya kwisakhono esilungileyo (ngokuqhelekileyo i-50 ukuya kwi-60 Hz), iya kuvelisa indawo yokwandisa kunye nekhontrakthi yamagnetic, ngoko ke kuya kunyanzeliswa ekujikelezeni. Iinkqubo zokuguqula loo msinga wesibini ube ngumbane kunye nokuzinzisa imveliso; Isiginali, njenge-4-20mA okanye ukuvalwa koqhagamshelwano.

3. Umphumo we-Magnetoresistance-Magnetoresistance luphawu lwezinye izinto, kwaye ixabiso layo lokumelana lingatshintshwa ngokuhambelana nentsimi yamagnetic esetyenzisiweyo. Ukuba akukho flux yamagnetic isetyenzisiweyo, i-current iya kuhamba ngokuthe ngqo kwi-plate. Ukuba kufakwe i-magnetic flux, amandla e-Lorentz ngokomlinganiselo we-magnetic flux density aya kuyiphambukisa indlela yangoku. Ngokuphambuka kwendlela yangoku, umgama wangoku ohamba ngeplate uba yinde, nto leyo ekhokelela ekwandeni kokuchasana.
