Ama-Strain Gauges
Ama-Strain Gauge angu-cc781905-5cde-3194-bb3b-136bad5cf58d_devices asetshenziselwa ukukala uhlobo lwento. Iqanjwe ngu-Edward E. Simmons no-Arthur C. Ruge ngo-1938, uhlobo oluvame kakhulu lwegeji yohlobo oluhlanganisa ukusekelwa okuguquguqukayo okuvalayo okusekela iphethini ye-foil yensimbi. I-strain gauge ixhunywe entweni nge-adhesive efanelekile, njenge-cyanoacrylate. Njengoba into ikhubazekile, i-foil ikhubazekile, okwenza ukumelana kwayo kukagesi kushintshe. Lokhu kushintsha kokumelana, okuvame ukukalwa kusetshenziswa ibhuloho le-Wheatstone, kuhlobene nobunzima ngenani elaziwa ngokuthi yi-gauge factor.
I-strain gauge ithatha inzuzo yokuqhutshwa kukagesi kanye nokuncika kwayo ekuphatheni kahle kukagesi kakhondakta, okuyimpahla yayo, kodwa futhi nejiyomethri yomqhubi. Uma i-conductor kagesi yelulelwa ngaphakathi kwemikhawulo yokunwebeka kwayo kangangokuthi ingaphuki noma yonakale unomphela, izoba mincane futhi ibe yinde, izinguquko ezandisa ukumelana kwayo nogesi ekupheleni ukuya ekupheleni. Ngokuphambene, lapho ikhondakta icindezelwe ngendlela yokuthi ingabophi, izonwebeka futhi ibe mfushane, izinguquko ezehlisa ukumelana kwayo nogesi ekupheleni ukuya ekupheleni. Kusukela ekulinganisweni kokumelana kukagesi kwe-strain gauge, inani lengcindezi esetshenzisiwe lingachazwa. I-gauge yohlobo olujwayelekile ihlela umucu omude, ozacile we-conductive ngephethini e-zig-zag yemigqa ehambisanayo ukuze inani elincane lokucindezelwa liqonde lapho kuqondiswa khona imigqa ehambisanayo kuholela ekuhlanganiseni okukhudlwana ngokuphindaphindayo phezu kobude obusebenzayo bokhondatha. -futhi yingakho noshintsho olukhulu ngokuphindaphindayo ekuphikiseni-kunokubonakala ngomugqa owodwa oqondile ucingo conductive. Ama-gauge e-strain akala ukuguqulwa kwendawo kuphela futhi angenziwa amancane ngokwanele ukuvumela "isici esilinganiselwe" njengokuhlaziywa kokucindezeleka isifanekiso esingaphansi kwakho. Lokhu kungaba ngempumelelo kusetshenziswe ezifundweni zokukhathala zezinto.
Ukuze uthole ulwazi olwengeziwe mayelana nama-strain gauge, shayela noma uthumele i-imeyili ku-AGS-Industrial.
