Siab hloov 97137042 yog tsim rau Isuzu siab sensor

1. Qhov tseeb

Qhov tseeb yog qhov tseem ceeb ntawm kev ua tau zoo ntawm lub sensor, uas yog ib qho tseem ceeb txuas nrog rau kev ntsuas qhov tseeb ntawm tag nrho cov ntsuas ntsuas. Qhov siab dua qhov tseeb ntawm lub sensor, nws kim dua. Yog li ntawd, qhov tseeb ntawm lub sensor tsuas yog yuav tsum tau ua kom tau raws li qhov tseeb ntawm tag nrho cov kev ntsuas qhov system, thiab nws tsis tas yuav xaiv qhov siab dhau. Ua li no, peb tuaj yeem xaiv qhov pheej yig dua thiab yooj yim sensor ntawm ntau lub sensors uas ua tau raws li lub hom phiaj ntsuas tib yam.

Yog tias lub hom phiaj ntawm kev ntsuas yog qhov kev soj ntsuam zoo, cov sensors uas muaj qhov tseeb rov ua dua yuav tsum raug xaiv, tab sis cov neeg uas muaj qhov tseeb ntawm qhov tseeb yuav tsum tsis txhob xaiv; Yog tias nws yog rau kev ntsuas ntau, nws yuav tsum tau txais qhov ntsuas qhov tseeb, yog li nws yuav tsum tau xaiv cov sensors nrog cov qib siab txaus.

Rau qee qhov kev siv tshwj xeeb, yog tias nws tsis tuaj yeem xaiv lub sensor tsim nyog, peb yuav tsum tsim thiab tsim lub sensor peb tus kheej. Kev ua tau zoo ntawm tus kheej tsim sensor yuav tsum ua kom tau raws li qhov yuav tsum tau siv.

2. Zoo

Muaj ntau ntau yam ntawm cov neeg kho tshuab sensors, xws li kuj strain gauge siab sensor, semiconductor strain gauge siab sensor, piezoresistive siab sensor, inductive siab sensor, capacitive siab sensor, resonant siab sensor thiab capacitive acceleration sensor. Tab sis feem ntau siv yog piezoresistive siab sensor, uas tsis tshua muaj nqi, siab raug thiab zoo linear yam ntxwv.

3. Paub

Thaum decompressing lub resistive siab sensor, peb xub paub lub resistive strain gauge. Resistance strain gauge yog ib yam ntawm cov cuab yeej rhiab heev uas hloov cov kev hloov pauv ntawm qhov ntsuas mus rau hauv lub teeb liab hluav taws xob. Nws yog ib qho ntawm cov khoom tseem ceeb ntawm piezoresistive strain sensor. Hlau kuj strain gauges thiab semiconductor strain gauges yog dav siv. Muaj ob hom hlau tsis kam tiv thaiv kab ntsuas: hlau strain gauges thiab hlau foil strain gauges. Feem ntau, qhov ntsuas qhov ntsuas tau nruj nruj rau lub substrate uas ua rau cov neeg kho tshuab lim los ntawm cov nplaum tshwj xeeb. Thaum qhov kev ntxhov siab ntawm lub substrate hloov, qhov tsis kam ntawm qhov ntsuas qhov ntsuas hloov pauv, kom qhov hluav taws xob siv rau cov resistor hloov. Feem ntau, hom kev ntsuas ntsuas no muaj kev hloov pauv me ntsis thaum nws ntxhov siab. Feem ntau, hom kev ntsuas qhov ntsuas no ua rau tus choj txuas, uas tau nthuav dav los ntawm cov cuab yeej txuas ntxiv tom ntej thiab tom qab ntawd xa mus rau qhov kev ua haujlwm (feem ntau A / D hloov dua siab tshiab thiab CPU) rau kev tso saib lossis ua tiav.
