I-AutomoBlele ye-Aunji ye-Injini ye-Insound yoxinzelelo lwe-Quil yoxinzelelo lwe-1875784C92

I-1.Prinecle yokusebenza

Umgaqo wokuSebenza we-Strain Couge's Strain Gauge yi-phenomenon eyangeniswa ngcali ye-Surin kwiziseko zoomatshini, ngokuqhelekileyo ezaziwa njengeziphumo zoxinzelelo. Ixabiso lokuphiliswa komqhubi wesinyithi linokubonakaliswa yile fomyula ilandelayo:

R = ρ

Phi: ukunyeliswa kwentsimbi yentsimbi (ω / m)

I-S-Indawo enqamlezayo yomqhubi ()

I-L-ubude bomqhubi (m)

Makhe sithathe isiciko socingo lwentsimbi njengomzekelo. Xa i-wire yentsimbi iphantsi kwamandla angaphandle, ubude bayo kunye nendawo enqamlezayo iya kutshintsha. Ukusuka kule fomula ingentla, inokubonwa ngokulula ukuba ixabiso labo liya kutshintsha. Ukuba i-wire yentsimbi yoluliwe ngamandla angaphandle, ubude bayo buya kunyuka kwaye indawo yayo yokuwela ilizwe iya kuncipha, kwaye ixabiso lazo liya kunyuka. Xa ucingo luqhutywa ngamandla angaphandle, ubude bancipha kwaye icandelo lokuwela liyanda, kwaye ixabiso lokuchasana liyancipha. Logama nje utshintsho lokuchasana nokuchasana (luhlala i-voltage kuyo yonke imixhuzulwano ilinganiswa), imeko ye-trin ye-wire yocingo inokufunyanwa.

I-2.USPRINCECINCINCECY

I-Sorsor yokunganyangeki ye-Corrosion ayinaso usulelo lwamanzi, kwaye uxinzelelo lwenza ngqo umphezulu we-cephragm, ebangela ukuba i-diaphragm ibe nye. Ukuphefumla kwefilimu eziprintiweyo ziprintwe kumphezulu we-ceramic diaragrag kwaye ziqhagamshelwe ukwenza ibhulorho ye-HASTAHNATA (ibhulorho evaliweyo). Ngenxa yesiphumo sePiezoresticive yePiezoresticetor, ibhulorho ivelisa kakhulu i-voltage voltage ilingane nengcinezelo kwaye ihambelana ne-voltage yovuyo. Umqondiso oqhelekileyo ulungelelaniswe njenge-2.0 / 3.0 / 3.3 MV / v ngokweereyithi zoxinzelelo ezahlukeneyo. Nge-Laser Alibration, i-sensor inozinzo lobushushu obuphezulu kunye nokuzinza kwexesha. Inzwanor inolwazi lwayo lobushushu lwe-0 ~ 70 ℃ kwaye inokuba nxibelelana ngqo nemithombo yeendaba.

I-Ceramic sisixhobo esaziwayo esinengxaki enkulu, ukumelana nokuziphatha, ukunxiba ukunganyangeki, ukumelana nempembelelo kunye nokunganyangeki kwentshukumo. Ukuzinza kwe-curmal ye-ceramics kunye nokuxhathisa ifilimu yayo yefilimu kunokwenza uluhlu lwamaqondo obushushu obusebenza bungaphezulu kwe-40 ~ 135 ℃, kwaye uneendlela eziphezulu kunye nozinzo kumlinganiso. Isidanga sombane sombane> I-2KV, isiphumo semveliso eyomeleleyo kunye nokuzinza okuhle kwexesha elide. Izinzwa ze-ceramic ezineempawu eziphezulu kunye nexabiso eliphantsi ziya kuba yindlela yophuhliso lweenzwa zoxinzelelo. EYurophu naseMelika, kukho indlela yokutshintsha ngokupheleleyo ezinye iintlobo zezinzwa. EChina, abasebenzisi abaninzi basebenzisa iivoti ze-ceramic ukufumana indawo yokuhlala egcinwe kwinzwayo.
