Dulmar Guud
Caqabadda badbaadada ee go'doominta kuleylka ayaa go'doomin karta oo u beddeli karta calaamadaha thermocouple (TC) meelaha khatarta ah calaamadaha hadda jira ee 4-20mA, waxayna u soo saari kartaa aagga badbaadada. Caqabaddan badbaadada waxay leedahay magdhow isgoysyada qabow ee ku dhex jira waxaana si caqli leh loo habeyn karaa. Kala duwanaanshaha dhabta ah ee thermocouple-ka waxaa lagu dejin karaa barnaamijka kombiyuutarka. Waxay leedahay shaqooyinka digniinta jabka siligga iyo digniinta ka baxsan masaafada. Badeecadani waxay u baahan tahay sahay koronto oo madax-bannaan, oo leh sahay koronto oo go'doonsan, gelinta, iyo terminaalka wax soo saarka. "*" waxay u taagan tahay nooca gelinta ee thermocouple-ka, qaabka gaarka ahna waxaa lagu matalaa kood (fiiri "Nooca Calaamadda Soo-gelinta iyo Shaxda Kala-duwanaanshaha" wixii faahfaahin ah).
