Mwachidule
Chosinthira kutentha cha Thermocouple chokhala ndi chitetezo cha maopaleshoni chimatha kudzipatula ndikusintha ma siginecha a thermocouple (TC) DC kukhala ma siginali apano. Izi kutentha Converter ali anamanga-kuzizira mapeto chipukuta misozi ndipo akhoza mwanzeru kukhazikitsidwa. Mtundu weniweni wa thermocouple ukhoza kukhazikitsidwa kudzera pa mapulogalamu apakompyuta. Ili ndi ntchito za alamu yosweka waya komanso ma alarm akunja.
Izi zimafuna magetsi odziyimira pawokha, okhala ndi magetsi akutali, zolowetsa, ndi zotulutsa.

Chithunzi chojambula
Zindikirani:
1. PHG-11TT+sikuphatikiza gawo lachiwiri
2. Ntchito ya njanji yamagetsi ndi ntchito yosankha, ndipo ogwiritsa ntchito ayenera kufotokoza njira yoperekera mphamvu poyitanitsa
Kusankhidwa kwa zolumikizira njanji yamagetsi kungatanthauze patsamba 89 la "Annex"
