K19 firikwensin matsin lamba 2897690 don na'urorin injin diesel na Cummins

1. Semiconductor varistor nau'in na'ura mai ɗaukar nauyi.

(1) Ƙa'idar ma'auni na semiconductor piezoresistive matsa lamba firikwensin na'urar firikwensin piezoresistive semiconductor yana amfani da tasirin piezoresistive na semiconductor don canza matsa lamba zuwa siginar wutar lantarki daidai, kuma an nuna ka'idarsa a cikin Hoto 8-21.

Semiconductor nau'in ma'auni wani nau'i ne mai mahimmanci wanda ƙimar juriya zata canza daidai lokacin da aka ja ko danna shi. Ana haɗe ma'aunin ma'auni zuwa diaphragm na silicon kuma an haɗa su don samar da gadar Wheston. Lokacin da diaphragm na siliki ya lalace, kowane ma'aunin ma'auni yana ja ko danna shi kuma juriyarsa ta canza, kuma gadar zata sami fitowar wutar lantarki daidai.

(2) Tsarin firikwensin matsa lamba na piezoresistive An nuna abun da ke ciki na semiconductor piezoresistive firikwensin matsin lamba a cikin Hoto 8-22. Akwai diaphragm na siliki a cikin juzu'in jujjuya matsi na firikwensin, kuma nakasar matsawa na diaphragm na siliki zai samar da siginar wutar lantarki daidai. Ɗayan gefe na diaphragm na siliki shine vacuum, ɗayan kuma an gabatar da shi tare da matsa lamba na bututun ci. Lokacin da matsa lamba a cikin bututun ci ya canza, nakasar diaphragm na silicon zai canza daidai, kuma za a haifar da siginar wutar lantarki mai dacewa da matsa lamba. Mafi girman matsa lamba mai shiga, mafi girma nakasar diaphragm na silicon kuma mafi girman karfin fitarwa na firikwensin.

Semiconductor varistor nau'in shan firikwensin bugun bututu yana da fa'idodin layi mai kyau, ƙaramin tsari, babban daidaito da halayen amsawa mai kyau.

1) Nau'in gano mita: mitar oscillation na kewayawar oscillation yana canzawa tare da ƙimar ƙarfin matsi mai mahimmanci, kuma bayan gyare-gyare da haɓakawa, siginar bugun jini tare da mitar daidai da matsa lamba yana fitowa.

2) Nau'in gano ƙarfin wuta: canjin ƙimar ƙarfin ƙarfin matsi mai mahimmanci ana daidaita shi ta hanyar motsi mai ɗaukar nauyi da da'irar amplifier AC, an lalata ta ta da'ira mai ganowa, sannan tace ta kewayawa ta tace don fitar da siginar wutar lantarki daidai da canjin matsa lamba.
