Bayanin Samfurin
Wayar Thermocouple Type R
Bayanin Samfuri
Wayar thermocouple ta Type R wata na'urar thermocouple ce mai daraja wadda aka yi da ƙarfe mai inganci wadda ta ƙunshi ƙarfe mai ƙarfe mai kama da platinum-rhodium 13% (ƙafa mai kyau) da kuma platinum mai tsarki (ƙafa mai kyau). Tana cikin dangin thermocouple na platinum-rhodium, tana ba da kwanciyar hankali da daidaito mafi kyau a yanayin zafi mai yawa, musamman a tsakanin 1000°C zuwa 1600°C. Idan aka kwatanta da thermocouples na Type S, tana da ƙarin sinadarin rhodium a cikin ƙafa mai kyau, wanda ke ba da ingantaccen aiki a cikin aikace-aikacen zafi mai yawa na dogon lokaci.
