Mfundo Yogwirira Ntchito ndi Zosamala za Selo Yonyamula ya Mtundu wa S

Maselo olemera amtundu wa Sndi masensa omwe amagwiritsidwa ntchito kwambiri poyesa kupsinjika ndi kupanikizika pakati pa zinthu zolimba. Amadziwikanso kuti masensa okakamiza kuthamanga, amatchedwa chifukwa cha kapangidwe kawo kofanana ndi S. Mtundu uwu wa selo lolemera umagwiritsidwa ntchito m'njira zosiyanasiyana, monga masikelo a crane, masikelo olumikizirana, masikelo osinthira makina, ndi machitidwe ena oyesera mphamvu zamagetsi ndi zolemera.

Mfundo yogwira ntchito ya selo lolemera la mtundu wa S ndi yakuti thupi lolimba limadutsa mu kusintha kwa elastic pogwiritsa ntchito mphamvu yakunja, zomwe zimapangitsa kuti gauge yolimbana ndi resistance yomwe ili pamwamba pake isinthe mawonekedwe. Kusintha kumeneku kumapangitsa kuti kukana kwa gauge yolimbana ndi strain kusinthe, zomwe zimasinthidwa kukhala chizindikiro chamagetsi (voltage kapena current) kudzera mu dera loyezera lofanana. Njirayi imasintha bwino mphamvu yakunja kukhala chizindikiro chamagetsi choyezera ndi kusanthula.

Mukayika selo yonyamula katundu ya mtundu wa S, zinthu zingapo zofunika kuziganizira. Choyamba, muyenera kusankha mtundu woyenera wa sensa ndipo katundu woyesedwa wa sensa uyenera kudziwika kutengera malo ogwirira ntchito ofunikira. Kuphatikiza apo, selo yonyamula katundu iyenera kusamalidwa mosamala kuti mupewe zolakwika zambiri zotulutsa. Musanayike, mawaya ayenera kuchitidwa motsatira malangizo omwe aperekedwa.

Tiyeneranso kudziwa kuti chipinda cha sensa, chivundikiro choteteza, ndi cholumikizira cha lead zonse zatsekedwa ndipo sizingatsegulidwe nthawi iliyonse yomwe mukufuna. Sikoyeneranso kukulitsa chingwecho nokha. Kuti muwonetsetse kuti ndi cholondola, chingwe cha sensa chiyenera kusungidwa kutali ndi mizere yamphamvu yamagetsi kapena malo okhala ndi mafunde othamanga kuti muchepetse kukhudzidwa kwa magwero osokoneza omwe ali pamalopo pa kutulutsa kwa chizindikiro cha sensa ndikuwonjezera kulondola.

Mu ntchito zolondola kwambiri, tikulimbikitsidwa kutentha sensa ndi chida kwa mphindi 30 musanagwiritse ntchito. Izi zimathandiza kuonetsetsa kuti muyeso ndi wolondola. Potsatira malangizo awa okhazikitsa, masensa olemera amtundu wa S amatha kuphatikizidwa bwino m'njira zosiyanasiyana zoyezera, kuphatikizapo kugwiritsa ntchito ma hopper weighing ndi silo weighing, kuti apereke miyezo yolondola komanso yokhazikika.
