Displacement sensor txhais
Kev daws teeb meem sensor, tseem hu ua linear sensor, yog ib qho khoom siv ncaj qha rau cov hlau induction. Kev ua haujlwm ntawm lub ntsuas hluav taws xob yog hloov ntau yam ntsuas ntsuas lub cev rau hauv hluav taws xob. Hauv cov txheej txheem tsim tawm, ntsuas kev ntsuas hluav taws xob feem ntau muab faib ua ob hom: ntsuas qhov loj me ntawm lub cev thiab kev tshem tawm tshuab. Raws li daim ntawv ntawm cov ntsuas qhov sib txawv hloov pauv hloov mus, qhov ntsuas hluav taws xob hloov tau tuaj yeem muab faib ua analog thiab digital. Hom analog tuaj yeem faib ua ob hom: hom lub cev thiab hom txheej txheem. Cov khoom siv txav chaw tawm suab feem ntau yog cov qauv siv sab nrauv, suav nrog lub zog hluav taws xob (potentiometer) hloov chaw, cov khoom siv hluav taws xob tsis sib xws, cov cuab yeej tus kheej, cov tshuab hluav taws xob tsis zoo, cov khoom siv tsis zoo tam sim no, thiab cov cuab yeej ua haujlwm. Qhov zoo tseem ceeb ntawm cov hluav taws xob hloov chaw digital yog qhov yooj yim nrog cov cim uas tuaj yeem xa ncaj qha mus rau lub koos pij tawj. Xws li cov pa hluav taws xob tau hloov zuj zus thiab tau siv ntau dua.
