1.ụkpụrụ ọrụ

Ụkpụrụ na-arụ ọrụ nke nguzogide nguzogide ígwè bụ ihe na-eme na nguzogide nguzogide na-agbanwe na ihe ndabere na-agbanwe site na nrụrụ igwe, nke a na-akpọkarị mmetụta mgbochi mgbochi.Enwere ike igosipụta uru nguzogide nke onye nduzi igwe site na usoro a:

R=ρ

Ebe: ρ-resistivity nke metal conductor (ω/m)

S—— Ofe akụkụ nke onye nduzi ()

L-ogologo onye nduzi (m)

Ka anyị were nkwụsi ike nke waya igwe dịka ọmụmaatụ.Mgbe a na-edobe waya igwe n'okpuru ike mpụga, ogologo ya na mpaghara mpaghara ga-agbanwe.Site na usoro a dị n'elu, enwere ike ịhụ ya ngwa ngwa na uru nkwụsị ya ga-agbanwe.Ọ bụrụ na a na-agbatị waya ígwè ahụ site na ike mpụga, ogologo ya ga-abawanye na mpaghara akụkụ ya ga-ebelata, uru nkwụsị ya ga-abawanye.Mgbe a na-ejikọta waya site na ike mpụga, ogologo oge na-ebelata na akụkụ obe na-abawanye, na uru nkwụsị na-ebelata.Ọ bụrụhaala na a na-atụle mgbanwe nke nguzogide (na-emekarị voltaji gafee nguzogide), enwere ike nweta ọnọdụ nsogbu nke eriri eriri.

2.Principle ngwa

Ihe mmetụta nrụgide seramiiki na-eguzogide corrosion enweghị nnyefe mmiri, na nrụgide na-arụ ọrụ ozugbo n'ihu ihu nke seramiiki diaphragm, na-eme ka diaphragm ahụ gbanwee ntakịrị.A na-ebipụta ndị na-emegide ihe nkiri siri ike na azụ azụ nke seramiiki diaphragm ma jikọọ ya iji mepụta akwa Wheatstone (akwa mechiri emechi).N'ihi mmetụta piezoresistive nke piezoresistor, àkwà mmiri ahụ na-emepụta mgbama voltaji dị elu nke kwekọrọ na nrụgide yana kwa nhata na voltaji mkpali.A na-ahazi akara ngosi ọkọlọtọ ka 2.0/3.0/3.3 mV/V dabere na oke nrụgide dị iche iche.Site na nhazi nke laser, ihe mmetụta ahụ nwere nkwụsi ike dị elu na nkwụsi ike oge.Ihe mmetụta nwere ụgwọ okpomọkụ nke ya nke 0 ~ 70 ℃ ma nwee ike ịnọ na kọntaktị na ọtụtụ mgbasa ozi.

Seramiiki bụ ihe a ma ama nke nwere nnukwu ngbanwe, nguzogide corrosion, nguzogide iyi, nguzogide mmetụta na nguzogide vibration.The thermal kwụsie ike nke ceramik na oké film eguzogide nwere ike ime ka ya na-arụ ọrụ okpomọkụ nso dị elu dị ka-40 ~ 135 ℃, na o nwere elu ziri ezi na kwụsie ike na nha.Ogo mkpuchi ọkụ eletrik> 2kV, mgbama mmepụta siri ike yana nkwụsi ike ogologo oge.Ihe mmetụta seramiiki nwere njirimara dị elu na ọnụ ala dị ala ga-abụ ntụziaka mmepe nke mmetụta nrụgide.Na Europe na America, enwere usoro iji dochie ụdị sensọ ndị ọzọ kpamkpam.Na China, ọtụtụ ndị ọrụ na-eji ihe mmetụta seramiiki dochie ihe mmetụta nrụgide silicon gbasasịrị.
