3. Kev ua haujlwm ntawm Hall tam sim no sensor
Lub hauv paus ntsiab lus ua haujlwm ntawm Hall tam sim no sensor tuaj yeem ua luv luv raws li cov kauj ruam hauv qab no:
3.1 Siv tam sim no: Siv qhov tam sim no los ntsuas ntawm qhov kawg ntawm qhov ntsuas tam sim no Hall. Qhov tam sim no ntws los ntawm tus neeg xyuas pib thiab tsim ib qho chaw sib nqus hauv cheeb tsam Hall ntawm tus neeg xyuas pib.
3.2 Them sib cais: Raws li Hall nyhuv, cov neeg nqa khoom raug cuam tshuam los ntawm Lorentz quab yuam, ua rau kev sib cais ntawm ob sab ntawm tus neeg xyuas pib. Raws li kev ua haujlwm ib txwm muaj, tus nqi sib cais yog proportional rau qhov ntsuas tam sim no.
3.3 Tsim cov peev txheej Hall: Kev sib cais ua rau muaj qhov sib txawv ntawm ob sab ntawm tus neeg xyuas pib, ua rau Hall muaj peev xwm. Qhov loj ntawm Hall muaj peev xwm muaj feem xyuam rau cov nqi sib cais thiab lub zog ntawm sab nraud magnetic teb.
3.4 Kev Ua Teeb Meem: Ntsuas thiab ua kom muaj peev xwm ntawm Hall los ntawm cov khoom siv hluav taws xob, thiab hloov nws mus rau hauv lub teeb liab tam sim no lossis voltage. Lub teeb liab tso zis yog proportional rau lub input tam sim no, yog li ua tiav kev ntsuas tam sim no.
4. Cov yam ntxwv thiab kev siv ntawm Hall tam sim no sensors
Hall tam sim no sensors muaj ntau yam ntxwv, nrog rau siab linearity, me me xoom drift, ceev teb ceev, thiab muaj zog tsis kam mus sib nqus cuam tshuam. Nyob rau tib lub sij hawm, nws kuj muaj cov yam ntxwv ntawm adjustable rhiab heev, dav kev khiav hauj lwm kub ntau yam thiab loj dynamic ntau yam.
Vim yog cov yam ntxwv saum toj no, Hall tam sim no sensors tau siv dav hauv ntau qhov chaw, xws li cov khoom siv hluav taws xob hluav taws xob, hluav taws xob tsheb, kev lag luam automation, lub zog saib xyuas, thiab lwm yam. Nws tuaj yeem ntsuas DC tam sim no thiab AC tam sim no nrog kev ruaj ntseg zoo thiab raug. Nyob rau tib lub sijhawm, vim nws tsis yog - kev tiv tauj thiab cov yam ntxwv ntawm kev siv hluav taws xob tsawg, nws kuj yog qhov tsim nyog rau kev saib xyuas tam sim no thiab kev kuaj xyuas lub zog.
Yuav kom suav tau, Hall tam sim no sensor yog ntsuas ntsuas tam sim no raws li Hall effect. Nws txoj haujlwm ua haujlwm yog tsim kom muaj peev xwm Hall los ntawm kev siv tam sim no, thiab tom qab ntawd tau txais cov teeb liab tam sim no los ntawm kev ua cov teeb liab. Vim nws cov yam ntxwv zoo heev thiab ntau yam kev siv, Hall tam sim no sensors ua lub luag haujlwm tseem ceeb hauv kev siv tshuab hluav taws xob niaj hnub no.
