Tsawg-voltage sensor LC52S00019P1 haum rau excavator qhov chaw SK200

Inevitable yuam kev editing

Thaum xaiv lub siab sensor, peb yuav tsum xav txog nws qhov tseeb, thiab dab tsi cuam tshuam rau qhov tseeb ntawm lub siab sensor? Qhov tseeb, muaj ntau yam uas ua rau muaj qhov yuam kev sensor. Cia peb ua tib zoo saib rau plaub yam uas tsis tuaj yeem zam tau, uas yog thawj qhov yuam kev ntawm lub sensor.

Ua ntej ntawm tag nrho cov, offset yuam kev: Vim hais tias lub ntsug offset ntawm lub siab sensor tseem nyob tas li nyob rau hauv tag nrho cov siab ntau yam, qhov txawv ntawm transducer diffusion thiab laser hloov thiab kho yuav ua offset yuam kev.

Qhov thib ob, qhov yuam kev rhiab heev: qhov yuam kev yog proportional rau lub siab. Yog tias qhov rhiab heev ntawm cov cuab yeej siv siab dua li tus nqi raug, qhov rhiab heev yuam kev yuav yog ib qho kev ua haujlwm ntawm lub siab. Yog tias qhov rhiab heev yog qis dua tus nqi raug, qhov kev xav yuam kev yuav yog qhov txo qis ntawm lub siab. Yog vim li cas rau qhov kev ua yuam kev no yog nyob rau hauv kev hloov ntawm cov txheej txheem diffusion.

Qhov thib peb yog qhov yuam kev linearity: qhov no yog qhov cuam tshuam me ntsis ntawm qhov kev ua yuam kev ntawm lub siab sensor, uas yog tshwm sim los ntawm lub cev nonlinearity ntawm silicon wafer, tab sis rau lub sensor nrog amplifier, nws yuav tsum muaj xws li cov nonlinearity ntawm lub wafer. amplifier. Lub linear yuam kev nkhaus tuaj yeem yog concave lossis convex.

Thaum kawg, qhov yuam kev hysteresis: feem ntau, hysteresis yuam kev ntawm lub siab sensor tuaj yeem tsis quav ntsej kiag li, vim hais tias cov silicon wafer muaj cov neeg kho tshuab siab tawv. Feem ntau, nws tsuas yog tsim nyog los xav txog qhov yuam kev lag luam thaum lub siab hloov pauv loj heev.

Cov plaub qhov yuam kev ntawm lub siab sensor yog inevitable. Peb tsuas tuaj yeem xaiv cov cuab yeej ua haujlwm siab thiab siv cov cuab yeej siv siab los txo cov kev ua yuam kev no. Peb kuj tuaj yeem ntsuas qee qhov yuam kev thaum tawm hauv lub Hoobkas kom txo tau qhov yuam kev ntau li ntau tau kom tau raws li qhov xav tau ntawm cov neeg siv khoom.
