Kuhlelo lokushisa, ukuqapha amandla okushisa kuyisixhumanisi esibaluleke kakhulu.
Imitha yokushisa ye-electromagnetic elawulwa eMelika isetshenziselwa ukubala ukushisa okusendaweni futhi ilawule izinga lokushisa elisendaweni ukuze kuqinisekiswe ukuthi ngeke kube khona ukushisa ngokweqile futhi kufezwe injongo yokonga amandla.
Indawo iyipulazi lezingulube, kanti izinto ezikhona endaweni zihlinzeka ngokushisa endlini yezingulube ukuze kugcinwe indlu yezingulube isesimweni sokushisa. Ukuze kuvinjwe indlu yengulube ekushiseni ngokweqile, imitha yokushisa kagesi ikala ukushisa epayipini ukuze ilawule iphampu yokushisa ukuze indlu yengulube ifinyelele esimweni sokushisa esingaguquki futhi ibone umphumela wokonga amandla.
Endaweni yokusetshenziswa, imitha yokushisa ka-electromagnetic ingabonisa ukugeleza okukhona ngaleso sikhathi, ukugeleza okunqwabelene, ukupholisa okusheshayo nokufudumeza, ukupholisa nokufudumeza okunqwabelene, izinga lokushisa lokungena, nezinga lokushisa lokuphuma. Umsebenzisi akadingi ukulungisa iphutha kusayithi. Ukulungisa iphutha kuqediwe ngaphambi kokuphuma embonini. Ngemva kokufaka inzwa ye-calorimeter ebandayo kanye nezinzwa zezinga lokushisa, zingasetshenziswa ngokuqondile ukuze zibone ukulinganisa okuzenzakalelayo esizeni nokulawula izinga lokushisa. Ithuluzi liza nokuxhumana kwe-4-20mA, Pulse kanye ne-RS485, okungabhekwa futhi kulawulwe maphakathi.
