Mmekọrịta dị n'etiti ihe mmetụta nrụgide piezoresistive na mmepụta

Ihe mmetụta nrụgide Piezoresistive bụ ụdị ihe mmetụta nrụgide na-eji mmetụta piezoresistive tụọ nrụgide. Mmetụta piezoresistive na-ezo aka na ngbanwe nke nguzogide eletriki nke ihe mgbe ọ na-enwe nsogbu n'ibu ma ọ bụ nrụrụ. Na ihe mmetụta nrụgide piezoresistive, a na-ejikarị diaphragm ma ọ bụ akpụkpọ anụ mee ihe iji gbanwee nrụgide etinyere ka ọ bụrụ nrụrụ arụ ọrụ, nke na-eme ka mgbanwe dị na nguzogide nke ihe piezoresistive.

Mmekọrịta dị n'etiti nrụgide na mmepụta maka ihe mmetụta nrụgide piezoresistive na-emetụta imewe na ihe onwunwe nke ihe mmetụta. Nke a bụ nkọwa nke mmekọrịta izugbe:

1.Direct Propotional Relationship:

N'ọtụtụ ihe mmetụta nrụgide piezoresistive, enwere mmekọrịta kpọmkwem na nke ziri ezi n'etiti nrụgide etinyere na mgbanwe nke nguzogide eletrik. Ka nrụgide na-abawanye, diaphragm ma ọ bụ akpụkpọ anụ nke ihe mmetụta na-enwe nrụrụ, na-eme ka ihe ndị na-emepụta ihe na-eme ka ọ bụrụ ihe mgbagwoju anya. Nsogbu a na-eduga na mgbanwe nke nguzogide, mgbanwe a na-adaba na nrụgide etinyere. Enwere ike tụọ ngbanwe nke nguzogide site na iji sekit akwa Wheatstone ma ọ bụ usoro mgbaama ndị ọzọ.

2.Wheatstone Bridge nhazi:

Ihe mmetụta nrụgide Piezoresistive na-ejikarị sekit akwa mmiri Wheatstone tụọ mgbanwe na nguzogide nke ọma. Sekit akwa mmiri nwere ọtụtụ ihe piezoresistive, ụfọdụ n'ime ha na-enwe nrụgide na-akpata, ebe ndị ọzọ adịghị. A na-eji mgbanwe dị iche iche dị na nguzogide n'etiti ihe ndị na-eme ka ọ bụrụ ihe na-adịghị mma na-emepụta ihe na-emepụta voltaji nke kwekọrọ na nrụgide etinyere.

3. Ngosipụta ihe nrụpụta:

Mpụta nke ihe mmetụta nrụgide piezoresistive bụ mgbama voltaji analọg. Ihe mmepụta voltaji kwekọrọ na mgbanwe nke nguzogide na, n'ihi ya, nrụgide etinyere. Enwere ike iji sekit na-eme ka mgbama mee ka ọ dịkwuo elu, nzacha, na mezie mgbama mmepụta iji nweta agụ nrụgide ziri ezi.

4.Nhazi:

N'ihi n'ichepụta ndidi na ọdịiche dị na ihe mmetụta ihe mmetụta, ihe mmetụta nrụgide piezoresistive na-achọkarị mmezi iji hụ na nha nrụgide ziri ezi. Nhazi nhazi gụnyere ịchọpụta njikọ dị n'etiti voltaji mmepụta ihe mmetụta yana nrụgide a na-etinye n'ezie. Enwere ike nweta nhazi nhazi a site na nnwale na ntụnyere megide ọkọlọtọ ntụaka.

Na nchịkọta, mmekọrịta dị n'etiti nrụgide na mmepụta maka ihe mmetụta nrụgide piezoresistive na-abụkarị ahịrị na nhata. Ka nrụgide na-abawanye, nkwụsị nke ihe mmetụta na-agbanwe, na-eduga na mgbanwe kwekọrọ na voltaji mmepụta. Nhazi akwa mmiri Wheatstone na ntụzịaka mgbaama na-arụ ọrụ dị mkpa n'ịgbanwe mgbanwe nguzogide ka ọ bụrụ njiri nrụgide kwesịrị ekwesị na nke ziri ezi.
