Isicelo
Isixhobo soKhuseleko se-Field Instrument Surge sikulungele ukukhusela iintlobo ngeentlobo zezixhobo, ezibandakanya:
I-1.2-ingcingo, i-3-ingcingo, kunye ne-4-wire transmitters:Ezi zidluliseli ziqhele ukusetyenziselwa ukulinganisa iiparamitha ezahlukeneyo ezinje ngoxinzelelo, ubushushu, inqanaba, njalo njalo, kwiindawo ezinobungozi.
I-2.Thermocouples (TC) kunye ne-Resistance Temperature Detectors (RTD):Ezi zinzwa zobushushu zihlala zisetyenziswa kwiinkqubo zoshishino ukulinganisa ubushushu ngokuchanekileyo nangokuthembekileyo.
3.Unxibelelwano lonxibelelwano olunje ngeRS485, RS232, kunye neRS422:Olu nxibelelwano lusetyenziselwa unxibelelwano lwedatha phakathi kwezixhobo ezahlukeneyo, ukuqinisekisa ukuhambelana kunye nokuhlanganiswa okungenamthungo ngaphakathi kweenkqubo.
4.Iimitha zokuhamba:Iimitha ezihambayo zisetyenziselwa ukulinganisa isantya sokuhamba kolwelo okanye iirhasi kwimibhobho okanye kwiinkqubo, ukubonelela ngedatha ebalulekileyo yolawulo lwenkqubo kunye nokubeka iliso.
5.Iivalvu zombane:Ezi zivalo zilawula ukuhamba kolwelo kwiinkqubo zemizi-mveliso kwaye zibalulekile ekulawuleni ukuhamba kolwelo okanye iigesi kwimibhobho.
