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 (chomwe chimatchedwa thupi la masika) 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.

Kodi pali masensa amtundu wanji?

Pali mitundu yosiyanasiyana ya maselo onyamula katundu, kutengera zomwe amapangidwira.Ma cell opindika kapena kumeta ubweya amagwiritsidwa ntchito ngati masikelo apulatifomu ndi zina zotero.Selo yonyamula katundu nthawi zambiri imayikidwa pansi pa kapangidwe kake (chotengera, silo, etc.), yomwe imanyamula zinthu zolemetsa kuchokera pamwamba ndipo nthawi zambiri imapangidwira katundu wapamwamba.Kumbali ina, kwa selo yonyamula katundu wokoka, kulemera kumagwirizanitsidwa ndi selo yolemetsa.Load cell ndi gawo lofunikira pakukula kwa nsanja komanso kukula kwa nsanja.

Kodi sensor imagwira ntchito bwanji?

Ngakhale zinthu za elastomer ndi zokhazikika, zimakhalanso ndi mphamvu zochepa.Izi zikutanthauza kuti pamene kulemera kwayikidwa pa sikelo, mphamvuyo imagwira ntchito pa thupi lotanuka.Mawu akuti elastomer poyambilira amachokera ku mfundo yakuti zinthuzi zimapunduka pang'ono chifukwa cha izi, koma ngati palibe mphamvu zomwe zimagwiritsidwa ntchito pa izo, zidzabwerera ku mawonekedwe ake oyambirira, ndiko kuti, "elasticity".Uku ndiye kusinthika kwa elasticity kwa chinthu choyezera.
