Ihe mmetụta nrụgide mmanụ K19 2897690 maka ngwa Cummins diesel engine

1. Semiconductor varistor ụdị ihe mmetụta nrụgide.

(1) Ntụle ụkpụrụ nke semiconductor piezoresistive pressure sensọ Semiconductor piezoresistive pressure sensọ na-eji mmetụta piezoresistive nke semiconductor iji gbanwee nrụgide n'ime akara voltaji kwekọrọ, na ụkpụrụ ya gosipụtara na Figure 8-21.

Ihe nleba anya nke Semiconductor bụ ụdị mmewere nwere mmetụta nke uru nguzogide ya ga-agbanwe n'otu aka ahụ mgbe a dọkpụrụ ya ma ọ bụ pịa ya. A na-ejikọta ihe nlele ahụ na silicon diaphragm ma jikọọ ya iji mepụta akwa Wheston. Mgbe diaphragm silicon diaphragm mebiri emebi, a na-adọta ma ọ bụ pịa ihe nlele ọ bụla na nguzogide ya na-agbanwe, na akwa mmiri ga-enwe mmepụta voltaji kwekọrọ.

(2) Nhazi nke ihe mmetụta nrụgide ihe oriri nke piezoresistive Ihe mejupụtara nke semiconductor piezoresistive inte pressure sensọ na-egosi na Figure 8-22. Enwere diaphragm silicon na ihe ngbanwe nrụgide nke ihe mmetụta, na nrụrụ mkpakọ nke silicon diaphragm ga-emepụta akara voltaji kwekọrọ. Otu akụkụ nke diaphragm silicon bụ oghere, akụkụ nke ọzọ na-ebute nrụgide ọkpọkọ oriri. Mgbe nrụgide dị na ọkpọkọ oriri na-agbanwe, nrụrụ nke diaphragm silicon ga-agbanwe ya, na mgbama voltaji kwekọrọ na nrụgide oriri ga-eme. Ka nrụgide ntinye dị ukwuu, ka nrụrụ nke diaphragm silicon na-abawanye na nrụgide mmepụta nke ihe mmetụta.

The semiconductor varistor ụdị oriri ọkpọkọ ihe mmetụta mmetụta nwere uru nke ezi linearity, obere structural size, elu izi ezi na ezi nzaghachi àgwà.

1) Ụdị nchọpụta ugboro ugboro: ugboro ole oscillation nke sekit oscillation na-agbanwe na uru capacitance nke ihe mmetụta nrụgide, na mgbe emezigharị na mmụba, a na-emepụta mgbaàmà pulse na ugboro ugboro kwekọrọ na nrụgide.

2) Ụdị nchọpụta voltaji: mgbanwe nke uru capacitance nke ihe mmetụta nrụgide na-agbanwe site na ụgbọ mmiri na-ebufe na sekit amplifier AC, na-emegharị ya site na sekit ihe nchọpụta, wee kpochaa ya site na sekit nzacha ka ọ pụta ìhè voltaji kwekọrọ na mgbanwe nrụgide.
