K19 isivamvo soxinzelelo lwamafutha 2897690 kwiCummins yezixhobo zedizili

1. I-Semiconductor varistor yohlobo lokuthatha uxinzelelo lwenzwa.

(1) Umgaqo wokulinganisa we-semiconductor piezoresistive pressure sensor sensor ye-semiconductor piezoresistive pressure sensor isebenzisa umphumo we-piezoresistive we-semiconductor ukuguqula uxinzelelo kwisignali ye-voltage ehambelanayo, kwaye umgaqo wayo uboniswe kuMfanekiso 8-21.

Igeyiji yoxinzelelo lweSemiconductor luhlobo lwesiqalelo esibuthathaka esinexabiso lokumelana nalo liya kutshintsha ngokuhambelanayo xa itsalwa okanye icinezelwa. Iigeyiji zoxinzelelo zincanyathiselwe kwi-silicon diaphragm kwaye ziqhagamshelwe ukwenza ibhulorho ye-Wheston. Xa i-silicon diaphragm ikhubazekile, igeyiji nganye yoxinzelelo iyatsalwa okanye icinezelwe kwaye ukuchasana kwayo kuyatshintsha, kwaye ibhulorho iya kuba nemveliso yombane ehambelanayo.

(2) Isakhiwo se-piezoresistive intake pressure sensor Ukubunjwa kwe-semiconductor piezoresistive intake pressure sensor sensor kuboniswe kuMzobo 8-22. Kukho i-silicon diaphragm kwindawo yokuguqulwa koxinzelelo lwenzwa, kunye ne-compression deformation ye-silicon diaphragm iya kuvelisa imiqondiso yombane ehambelanayo. Elinye icala le-silicon diaphragm liyivacuum, kwaye elinye icala laziswa ngoxinzelelo lombhobho wokuthatha. Xa uxinzelelo kumbhobho wokungena lutshintsha, i-deformation ye-silicon diaphragm iya kutshintsha ngokufanelekileyo, kwaye isignali ye-voltage ehambelana noxinzelelo lokungena iya kuveliswa. Uxinzelelo olukhulu lokungena, kokukhona ukuguqulwa kwe-silicon diaphragm kunye noxinzelelo olukhulu lwemveliso yenzwa.

I-semiconductor ye-varistor yohlobo lokuthatha i-sensor ye-pipe pressure sensor ineenzuzo zokulandelelana kakuhle, ubungakanani obuncinci besakhiwo, ukuchaneka okuphezulu kunye neempawu zokuphendula ezilungileyo.

I-1) Uhlobo lokufumanisa i-Frequency: i-oscillation frequency ye-oscillation ye-circuit circuit itshintsha ngexabiso le-capacitance ye-element ebucayi yoxinzelelo, kwaye emva kokulungiswa kunye nokukhulisa, isignali ye-pulse kunye ne-frequency ehambelana noxinzelelo luphuma.

I-2) Uhlobo lokubona i-voltage: utshintsho lwexabiso le-capacitance ye-element ebucayi yoxinzelelo imodareyithwa yi-carrier wave kunye ne-AC amplifier circuit, ithotywe yi-circuit ye-detector, kwaye ihlulwe ngesiphaluka sokucoca umbane we-voltage ophumayo ohambelana nokutshintsha koxinzelelo.
