Muaj ntau ntau hom kev siab sensors. Nov yog qee qhov ntau tshaj plaws:
1. Piezoresistive Pressure Sensor: Siv cov nyhuv piezoresistive ntawm cov khoom siv semiconductor los hloov cov kev hloov siab rau hauv kev hloov pauv. Nws muaj qhov zoo xws li qhov me me, qhov tseeb siab, thiab cov lus teb ceev ceev, thiab tau siv dav hauv ntau yam kev lag luam thiab cov khoom siv ntsuas.
2. Capacitive Pressure Sensor: ntsuas qhov siab los ntawm kev hloov pauv tus nqi capacitance ntawm lub capacitor. Nws feem ntau siv cov qauv capacitor sib txawv. Thaum lub siab yog siv rau lub sensor, qhov kev ncua deb los yog cheeb tsam ntawm lub capacitor daim hlau hloov, ua rau muaj kev hloov pauv ntawm tus nqi capacitance. Hom sensor no muaj qhov raug siab, qhov ntsuas dav dav, thiab kev ruaj ntseg zoo thiab linearity.
3. Piezoelectric Pressure Sensor: Raws li cov nyhuv piezoelectric, qee cov muaju ua kom muaj hluav taws xob thaum raug siab. Thaum lub siab raug siv rau cov khoom siv piezoelectric, lub teeb liab sib npaug rau lub siab yog generated. Tus nqi siab yog txiav txim siab los ntawm kev ntsuas tus nqi lossis qhov voltage. Nws nta cov lus teb ceev ceev thiab ntau qhov ntau zaus, thiab feem ntau yog siv rau siab -frequency dynamic siab ntsuas.
4. Strain Gauge Pressure Sensor: Qhov ntsuas no siv lub zog tsim los ntawm lub zog elastic nyob rau hauv siab. Ib qho kev ntsuas ntsuas uas txuas rau lub caij elastic converts lub strain rau hauv kev hloov hauv qhov tsis kam. Hom sensor no muaj cov qauv yooj yim, tus nqi qis, thiab tsim nyog rau kev ntsuas qhov dav dav.
5. Inductive Pressure Sensor: Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, lub sensor no ntsuas lub siab los ntawm kev hloov lub inductance ntawm lub inductor coil. Nws feem ntau siv qhov hloov pauv tsis txaus siab lossis cov qauv hloov pauv. Thaum lub siab raug siv rau lub sensor, nws ua rau muaj kev hloov pauv hauv qhov sib nqus Circuit Court lossis coil tsis, ua rau muaj kev hloov pauv hauv inductance. Nws muaj qhov ntsuas qhov tseeb thiab ruaj khov thiab tsim nyog rau kev ntsuas siab hauv qee qhov chaw tshwj xeeb.
6. Fiber Optic Pressure Sensor: Lub sensor no ntsuas lub siab los ntawm kev siv lub teeb kis tau tus yam ntxwv ntawm optical fibers thiab cov nyhuv ntawm lub siab ntawm fiber ntau. Lub siab yog hloov mus rau hauv qhov kev hloov pauv ntawm cov teeb liab kho qhov muag los ntawm kev khoov, ncab, lossis kev hloov pauv ntawm qhov refractive index ntawm fiber ntau, uas tom qab ntawd kuaj pom los ntawm photodetector. Hom sensor no muaj qhov zoo xws li kev tiv thaiv electromagnetic cuam tshuam, corrosion kuj, thiab siab rhiab heev, ua rau nws haum rau kev ntsuas siab nyob rau hauv ib puag ncig hnyav.
7. Ceramic Pressure Sensor: Lub sensor no siv cov ceramic ua qhov ntsuas qhov ntsuas thiab siv cov nyhuv piezoelectric lossis piezoresistive ntawm ceramics los ntsuas qhov siab. Cov khoom siv ceramic muaj cov yam ntxwv xws li kub tsis kam, tiv thaiv corrosion, thiab rwb thaiv tsev zoo, ua rau lawv haum rau kev ntsuas siab nyob rau hauv qee yam kev ua haujlwm tshwj xeeb.
8. Diffused Silicon Pressure Sensor: Lub sensor no sib txuas cov diffused silicon sensing lub caij mus rau ib nti, tsim ib tug resistive network los ntawm ib tug diffusion txheej txheem los hloov siab mus rau hauv kev hloov pauv. Nws muaj qhov zoo xws li qhov raug siab, kev ruaj ntseg zoo, thiab qhov ntsuas kub me me, thiab tau siv dav hauv ntau qhov siab - qhov ntsuas qhov ntsuas qhov tseeb.
