Yini aIsixhumi esiyindilinga?

A isixhumi esiyindilingaiyisilinda, isixhumi sikagesi esinamaphini amaningi esiqukethe abathintwayo abanikeza amandla, abadlulisa idatha, noma abadlulisela amasignali kagesi kudivayisi kagesi.

Kuwuhlobo oluvamile lwesixhumi sikagesi esinesimo esiyindilinga. Lesi sixhumi sisetshenziselwa ukuxhuma izinto ezimbili zikagesi noma izintambo futhi kuqinisekiswe ukuthi ukudluliswa kwezimpawu zikagesi noma amandla phakathi kwazo kuzinzile futhi kuthembekile.

Izixhumi eziyindilinga, ezaziwa nangokuthi “izixhumi eziyisiyingi”, ziyizixhumi zikagesi ezinamaphini amaningi angamacylindrical. Lawa madivayisi aqukethe abathintwayo abadlulisela idatha namandla. I-ITT yethula okokuqala izixhumi eziyindilinga ngeminyaka yawo-1930 ukuze zisetshenziswe ekwenziweni kwezindiza zempi. Namuhla, lezi zixhumi nazo zingatholakala kumishini yezokwelapha nakwezinye izindawo lapho ukwethembeka kubalulekile khona.

Izixhumi eziyindilinga ngokuvamile zinezindlu zepulasitiki noma zensimbi ezizungeza abathintwayo, ezishumekwe kumpahla evikelayo ukuze kugcinwe ukuqondanisa. Lawa matheminali ngokuvamile abhangqwa nezintambo, ukwakhiwa okuwenza amelane ikakhulukazi nokuphazamiseka kwemvelo kanye nokuhlukaniswa ngengozi.

Izinhlobo zezixhumi ezivame ukusetshenziswa ezimotweni (SAE J560, J1587, J1962, J1928 njengezibonelo):
