Sensor vs Transducer
Sensor thiab Transducer yog cov khoom siv lub cev uas siv rau hauv hluav taws xob, hluav taws xob thiab ntau lwm yam khoom siv thiab khoom siv. Qhov sib txawv ntawm sensor thiab transducer yog ib yam uas ntau tus neeg feem ntau tsis meej pem nrog thiab yuav tsum tau coj mus rau hauv lub teeb. Cov no yog cov cuab yeej siv lub cev uas siv rau hauv cov khoom siv hluav taws xob thiab hluav taws xob thiab feem ntau ntsib los ntawm kev siv tshuab. Thaum lub sensor yog ib qho khoom siv uas, raws li nws lub npe qhia, ntsuas lub cev kom muaj nuj nqis thiab tom qab ntawd hloov nws mus rau hauv cov cim uas tuaj yeem nyeem tau los ntawm tus neeg siv lossis los ntawm lwm yam cuab yeej. Transducer, ntawm qhov tod tes, yog cov cuab yeej siv lub cev (Electrical, electro-mechanical, electromagnetic, photonic lossis photovoltaic) uas hloov ib yam ntawm lub zog mus rau lwm qhov lossis lub cev muaj zog rau lwm tus rau lub hom phiaj ntawm kev ntsuas lossis hloov cov ntaub ntawv.
Nws yooj yim pom yog vim li cas tib neeg tsis meej pem ntawm transducers thiab sensors. Vim tias cov transducers feem ntau pom hauv cov sensors, tib neeg tsis ua qhov sib txawv. Transducers yog ib feem ntawm cov cuab yeej siv ntau dua thiab siv los hloov lub zog ntawm ib daim ntawv mus rau lwm qhov. Sensors yog siv los ntsuas thiab qhia cov qib ntsuas.
Tej yam ua nyuaj rau ntau tus thaum lawv pom ntau lub sensors siv cov kev sib txuas lus sib txuas txhawm rau txhawm rau txheeb xyuas cov qib zog thiab tom qab ntawd hloov lawv mus rau hauv hluav taws xob hluav taws xob uas cuam tshuam rau lub ntsuas ntsuas. Nyob rau hauv eighties, kev sib cuag transducers tau dhau los ua ntau qhov chaw thiab koj yuav tsum tau pom lawv ua cov kab xev taub hau hauv cov neeg ua si cassette. Cov transducers no tau kov daim kab xev sib nqus thiab nyeem cov ntaub ntawv sib nqus uas nyob ntawd. Cov ntaub ntawv no tau hloov mus rau hauv cov teeb liab hluav taws xob uas tau nqa los ntawm cov xov hlau mus rau cov neeg hais lus qhov twg thaum kawg nws tau hloov mus ua suab nthwv dej.
2nd hom transducers yog immersion transducers uas pom daim ntawv thov hauv cov kua dej. Cov transducers zoo ntsuas lub zog nyob rau hauv daim ntawv ntawm lub suab, siab los yog lwm yam hom ntawm txhua yam zog. Paintbrush transducers zoo ib yam li immersion transducers tshwj tsis yog tias lawv ua haujlwm hauv huab cua. Kav hlau txais xov nyob rau hauv xov tooj cua kom ntes tau xov tooj cua nthwv cua sau cua nthwv cua thiab hloov mus rau hauv hluav taws xob lub zog uas hloov rov qab mus rau lub suab zog uas koj hnov los ntawm cov neeg hais lus.
Sensors, ntawm qhov tod tes, yog qhov yooj yim dua vim tias lawv muaj lub hom phiaj ib leeg thiab qhov ntawd yog hloov hom zog thiab ua kom pom tseeb rau tib neeg kom nkag siab. Yuav kom ua tiav qhov kawg no, cov sensors siv cov transducers uas yog cov kws tshaj lij hauv kev hloov lub zog ntawm ib hom mus rau lwm qhov, feem ntau yog hluav taws xob nyob rau hauv cov ntaub ntawv ntawm cov sensors tso cai rau cov sensors tso saib nws digitally lossis nrog ib qho analog meter.
Summary
• Transducers thiab sensors yog cov khoom siv lub cev uas siv hauv hluav taws xob, hluav taws xob thiab ntau lwm yam khoom siv thiab khoom siv.
• Transducers yog siv los hloov ib hom hluav taws xob mus rau lwm qhov thaum lub ntsuas ntsuas ntsuas lub zog thiab hloov mus rau hauv cov teeb liab hluav taws xob uas ntsuas tau digitally.
