K19 fuel pressure sensor 2897690 yeCummins diesel engine accessories

1. Semiconductor varistor type intake pressure sensor.

(1) Kuyera musimboti we semiconductor piezoresistive pressure sensor Semiconductor piezoresistive pressure sensor inoshandisa piezoresistive effect ye semiconductor kushandura kudzvinyirirwa kuita signal yevoltage inoenderana, uye musimboti wayo unoratidzwa muMufananidzo 8-21.

Semiconductor strain gauge imhando yechinhu chakavanzika chine kukosha kwekupikisa kunochinja zvinoenderana kana ichidhonzwa kana kudzvanywa. Iwo majeji ekumanikidza akasungirirwa kune silicon diaphragm uye akabatana kuti agadzire Wheston zambuko. Kana iyo silicon diaphragm yakaremara, yega yega geji inodhonzwa kana kudzvanywa uye kuramba kwayo kunoshanduka, uye bhiriji rinenge riine inowirirana kubuda kwemagetsi.

(2) Chimiro chepiezoresistive intake pressure sensor Kuumbwa kwe semiconductor piezoresistive intake pressure sensor inoratidzwa muMufananidzo 8-22. Iko kune silicon diaphragm mune yekumanikidza kushandura chinhu che sensor, uye iyo compression deformation yesilicon diaphragm inoburitsa inoenderana magetsi masaini. Rimwe divi resilicon diaphragm is vacuum, uye rimwe divi rinounzwa nekumanikidza kwepombi yekupinza. Kana kudzvanywa kwepombi yekudya kuchichinja, deformation yesilicon diaphragm ichachinja zvinoenderana, uye chiratidzo chevoltage chinoenderana nekumanikidza kwekudya kunogadzirwa. Iyo yakakura iyo inlet kudzvanywa, iyo yakakura deformation yesilicon diaphragm uye yakakura yekubuda kweiyo sensor.

Iyo semiconductor varistor mhando yekudyara pombi yekumanikidza sensor ine zvakanakira mutsara wakanaka, diki diki dhizaini saizi, yakakwirira kurongeka uye yakanaka yekupindura maitiro.

1) Frequency yekuona mhando: iyo oscillation frequency ye oscillation wedunhu inoshanduka ne capacitance kukosha kweiyo pressure sensitive element, uye mushure mekugadzirisa uye kukwidziridzwa, iyo pulse siginecha ine frequency inoenderana nekumanikidza inobuda.

2) Voltage yekuona mhando: shanduko ye capacitance kukosha kweiyo pressure sensitive element inogadziriswa ne carrier wave uye AC amplifier circuit, yakaderedzwa ne detector circuit, yobva yapepetwa nefilter circuit kuti inobuda voltage signal inoenderana nepressure shanduko.
