Sensa imagwiritsidwa ntchito kudziwa kuchuluka kwake: mphamvu yokoka yomwe imapangidwa ndi sampuli imasinthidwa kukhala chizindikiro chamagetsi ndi sensor yolemera. Chifukwa chake, cell cell ndi gawo lamagetsi amagetsi.

Ukadaulo wogwiritsidwa ntchito kwambiri umachokera ku ukadaulo wa strain gauge: sensor yoyezera analoji imakhala ndi chinthu choyezera (chotchedwa masika thupi) chopangidwa ndi chitsulo kapena aluminiyamu, pomwe chowunikira (Wheatstone bridge) chimayikidwa. Sikelo iliyonse yamagetsi imakhala ndi selo lophatikizika lonyamula kuti liwonetsetse kuti kulemera kumatha kuyeza.

Masensa olemera a strain gauge amagwiritsidwa ntchito kwambiri, koma pali matekinoloje ena oyezera, monga ukadaulo wa electromagnetic force compensation EMFC, womwe kutsimikiza kwake kwa misa kumatheka popanda kutayika kwa mikangano. Nthawi zambiri, ma cell onyamula amayikidwa m'mafakitale, monga kudzaza mbewu, akasinja olemera, kudziwa kuchuluka kwa kudzaza, ndi zina.

Sensor wiring nthawizonse wakhala mmodzi wa mafunso anafunsidwa kwambiri mu ndondomeko zogula kasitomala, makasitomala ambiri sadziwa kulumikiza kachipangizo, Ndipotu, mawaya njira masensa osiyanasiyana kwenikweni chimodzimodzi, kupanikizika masensa zambiri ndi awiri dongosolo waya, mawaya atatu, mawaya anayi, ndi mawaya ena asanu.
Pressure sensor two-waya dongosolo ndi losavuta, makasitomala ambiri amadziwa waya, waya wolumikizidwa ndi magetsi abwino, mzere wina ndi mzere wamawu kudzera pa chida cholumikizidwa ndi magetsi oyipa, ichi ndi chosavuta, kuthamanga kachipangizo atatu-waya dongosolo ndi pamaziko a dongosolo awiri waya kuphatikiza mzere, mzere mwachindunji chikugwirizana ndi magetsi zoipa, mavuto kwambiri kuposa dongosolo awiri waya. Sensor yamphamvu yamawaya anayi ndizomwe zimalowetsa mphamvu ziwiri, ndipo zina ziwiri ndizotulutsa ma siginecha. Mawaya anayi nthawi zambiri amakhala otulutsa mphamvu kuposa 4 ~ 20mA, 4 ~ 20mA yotchedwa pressure transmitter, yopangidwa ndi mawaya awiri. Zina mwazomwe zimatuluka mu sensor ya pressure sizimakulitsidwa, ndipo kutulutsa kwathunthu kumangokhala mamilivolti makumi khumi, pomwe masensa ena opanikizika amakhala ndi amplifier dera mkati, ndipo kutulutsa kwathunthu ndi 0 ~ 2V. Ponena za momwe mungalandirire chida chowonetsera, zimatengera kukula kwa chidacho, ngati pali gear yomwe imagwirizana ndi chizindikiro chotulutsa, ikhoza kuyesedwa mwachindunji, mwinamwake ndikofunikira kuwonjezera dera losinthira chizindikiro. . Sensa yama waya asanu siwosiyana kwambiri ndi mawaya anayi, ndipo sensa yamawaya asanu pamsika ndi yochepa.
