Cov txheej txheem ntawm kev ntsuas siab yog muab piv nrog rau hom kev ntsuas siab.

1. Npog

Bellows yog siv los ntsuas qhov siab. Lawv tuaj yeem ua los ntawm cascaded capsules. Nws yog tsim los ntawm kev kho ntau tus neeg diaphragms ua ke. Bellows caij yog ib qho kev nthuav dav, foldable thiab axially hloov tau. Nws tuaj yeem ua los ntawm ib daim hlau nyias. Cov khoom sib xyaw ua ke yog tsim los ntawm cov kav dej dov, kos cov kav dej los ntawm hydroforming thiab tig los ntawm cov khoom siv hlau. Cov kua dej ua kua tuaj yeem siv tau rau ntau hom kev siv sensor.

(1) Qhov zoo ntawm lub tshuab nqus tsev

Tus nqi nruab nrab

Muab lub zog

Kev ua tau zoo nyob hauv nruab nrab thiab qis qis

(2) qhov shortcomings ntawm corrugated yeeb nkab

Tsis haum rau kev kub siab

Xav tau qhov kub thiab txias ambient

2. Lim siab sensor

Qhov no yog ib hom passive tsis kam siab sensor. Thaum nws stretched los yog compressed, nws kuj yuav hloov. Ib qho kev ntsuas ntsuas yog ib hom hlau. Thaum raug cov neeg kho tshuab strain, nws kuj yuav hloov vim lub cev muaj zog. Lub strain gauge txuas nrog lub diaphragm. Thaum lub diaphragm yog khoov vim yog siv lub siab, lub strain gauge yuav stretch los yog compress, thiab nws kuj yuav hloov vim qhov kev hloov no nyob rau hauv nws cross-sectional cheeb tsam. Qhov kev hloov pauv no tau hloov pauv mus rau qhov muab hluav taws xob los ntawm kev sib txuas ob lossis plaub meters zoo ib yam li tus choj Wheatstone, kom cov zis tuaj yeem ua kom tiav thiab qhov kev nkag siab ntawm qhov yuam kev tuaj yeem raug txo.

(1) Qhov zoo ntawm lub zog siab sensor

Yooj yim txij nkawm thiab yooj yim installation

Zoo raug thiab stability

Teb ceev ceev

Kev ntsuas dav

Tsis muaj qhov txav mus los thiab cov teeb liab tso tawm siab zog tawm ntawm qhov muaj peev xwm ntau

(2) Disadvantages ntawm strain siab sensor

Xav tau kev them nyiaj kub thiab qhov hluav taws xob tsis tu ncua

Kev nyeem ntawv hluav taws xob yog tsim nyog.

3. Piezoelectric siab sensor

Piezoelectric yog lub peev xwm ntawm qee cov ntaub ntawv (feem ntau muaju) los tsim hluav taws xob muaj peev xwm teb rau kev siv tshuab kev ntxhov siab. Nyob rau hauv no transducer, cov nyhuv piezoelectric yog siv rau qee cov ntaub ntawv (xws li Shi Ying) los tsim cov hluav taws xob sai sai thiab ntsuas qhov mob tshwm sim los ntawm lub siab ntawm kev hnov ​​​​mob. Cov hom piezoelectric siab sensors yog hom hom hom thiab tsis tshua muaj impedance voltage hom hom.

(1) Qhov zoo ntawm piezoelectric siab sensor

Zoo zaus teb, tsis xav tau rau sab nraud fais fab mov.

(2) Qhov tsis zoo ntawm piezoelectric siab sensor

Kev hloov pauv kub yuav cuam tshuam rau cov zis, thiab ntsuas tsis tau zoo li qub.

4. Piezoresistive sensor

Piezoresistance yog qhov kev hloov ntawm cov khoom siv los ntawm kev hloov ntawm kev ntxhov siab hauv cov khoom. Lub piezoresistive gauge factor txo qis nrog qhov nce ntawm qhov kub thiab txias. Lub sensor siv cov nyhuv no yog MEMS siab sensor raws li silicon, uas muaj ntau yam kev siv, xws li kev ntsuas ntshav siab thiab ntsuas lub log tsheb.
