Daim ntawv thov ntawm lub siab sensor

1. Ntau yam

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 muaj tus nqi qis heev, siab raug thiab zoo linear yam ntxwv.

2. Kev nkag siab

Nyob rau hauv lub decompression tsis kam siab sensor, peb xub to taub qhov kev tiv thaiv strain gauge no lub caij. Qhov ntsuas qhov ntsuas qhov ntsuas yog ib qho khoom siv rhiab 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. Feem ntau siv los tiv thaiv kab ntsuas ntsuas yog hlau tsis kam strain gauges thiab semiconductor strain gauges. Muaj ob hom hlau tsis kam tiv thaiv kab mob: hlau strain gauge thiab hlau foil strain gauge. Feem ntau, qhov ntsuas qhov ntsuas tau nruj nruj rau cov khoom siv sib xyaw matrix los ntawm tus neeg sawv cev tshwj xeeb. Thaum qhov kev ntxhov siab ntawm matrix hloov pauv, qhov ntsuas qhov ntsuas qhov ntsuas kuj tseem deforms, yog li ntawd qhov kev hloov pauv ntawm qhov ntsuas qhov ntsuas, thiab qhov ntsuas hluav taws xob tau siv rau qhov kev hloov pauv. Tus nqi tsis kam ntawm qhov ntsuas qhov ntsuas no feem ntau me me thaum nws ntxhov siab, thiab qhov ntsuas qhov ntsuas no feem ntau yog tsim los ntawm A strain choj, thiab tau nthuav dav los ntawm cov cuab yeej txuas ntxiv tom ntej, thiab tom qab ntawd xa mus rau kev ua haujlwm (feem ntau A / D hloov dua siab tshiab thiab CPU) tso saib lossis cov txheej txheem tswj hwm.
