1, raws li cov tswv yim uas yog, cov ntsiab lus sib txawv ntawm cov khoom ntsuas:

Yog tias cov khoom siv hluav taws xob tsis yog hluav taws xob xws li kub, siab, hloov pauv, ceev, av noo, lub teeb thiab roj, cov khoom siv sib txuas yog hu ua kub sensors, siab sensors thiab hnyav sensors.

Qhov kev faib tawm no qhia meej meej txog kev siv cov sensors, thiab muab kev yooj yim rau cov neeg siv. Nws yog ib qho yooj yim los xaiv qhov xav tau sensors raws li cov khoom ntsuas. Qhov tsis zoo yog tias txoj kev faib tawm no faib cov sensors nrog cov ntsiab lus sib txawv rau hauv ib pawg, thiab nws nyuaj rau nrhiav pom qhov sib xws thiab qhov sib txawv ntawm txhua lub sensor hauv kev hloov pauv. Yog li ntawd, nws yog qhov tsis zoo los ua kom paub qee cov ntsiab lus yooj yim thiab kev tshuaj xyuas ntawm cov sensors. Vim tias tib hom sensor, xws li piezoelectric sensor, tuaj yeem siv los ntsuas kev nrawm, nrawm thiab amplitude hauv cov tshuab kev co, thiab tseem tuaj yeem siv los ntsuas qhov cuam tshuam thiab quab yuam, tab sis nws txoj haujlwm ua haujlwm yog tib yam.

Txoj kev faib tawm no faib ntau yam ntawm lub cev kom muaj nuj nqis rau hauv ob pawg: qhov yooj yim kom muaj nuj nqis thiab cov khoom tau los. Piv txwv li, kev quab yuam tuaj yeem suav tias yog qhov tseem ceeb ntawm lub cev, los ntawm cov khoom siv lub cev xws li siab, qhov hnyav, kev ntxhov siab thiab lub zog tuaj yeem muab tau. Thaum peb xav tau los ntsuas cov khoom ntawm lub cev saum toj no, peb tsuas yog yuav tsum siv lub zog sensors. Yog li ntawd, kev nkag siab txog kev sib raug zoo ntawm cov khoom siv lub cev thiab cov khoom siv lub cev tau txais txiaj ntsig zoo heev rau lub kaw lus siv cov sensors.

2, raws li txoj cai ntawm kev ua haujlwm (nrhiav) kev faib tawm

Lub hauv paus ntsiab lus tshawb pom yog hais txog cov nyhuv ntawm lub cev, tshuaj lom neeg thiab cov nyhuv lom neeg uas lub sensor ua haujlwm. Muaj cov resistive, capacitive, inductive, piezoelectric, electromagnetic, magnetoresistive, photoelectric, piezoresistive, thermoelectric, nuclear hluav taws xob, semiconductor sensors thiab lwm yam.

Piv txwv li, raws li lub hauv paus ntsiab lus ntawm kev sib txawv kuj, muaj potentiometers, strain gauges, piezoresistive sensors thiab lwm yam. Piv txwv li, raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, muaj inductive sensors, sib txawv siab transmitters, eddy tam sim no sensors, electromagnetic sensors, magnetoresistive sensors thiab hais txog. Raws li kev tshawb xav ntawm semiconductor, muaj cov khoom siv hauv xeev xws li semiconductor force sensor, thermal sensor, photosensitive sensor, gas sensor thiab magnetic sensor.

Qhov zoo ntawm cov txheej txheem kev faib tawm no yog qhov yooj yim rau cov kws tshaj lij sensor los ua inductive tsom xam thiab kev tshawb fawb los ntawm lub hauv paus ntsiab lus thiab kev tsim, thiab nws zam ntau lub npe ntawm cov sensors, yog li nws feem ntau siv. Qhov tsis zoo yog tias cov neeg siv yuav xav tias tsis yooj yim thaum xaiv cov sensors.

Qee zaum, nws feem ntau muaj npe los ntawm kev sib txuas ntawm kev siv thiab lub hauv paus ntsiab lus, xws li inductive displacement sensor thiab piezoelectric force sensor, kom tsis txhob muaj ntau lub npe ntawm cov sensors.
