(S-type thermocouple) platinum rhodium 10-platinum thermocouple
Lub platinum rhodium 10-platinum thermocouple (S-type thermocouple) yog ib qho khoom muaj nqi hlau thermocouple. Txoj kab uas hla ntawm ob peb xaim yog teev raws li 0.5mm, thiab qhov yuam kev tso cai yog -0.015mm. Cov tshuaj nominal muaj pes tsawg leeg ntawm qhov zoo electrode (SP) yog platinum-rhodium alloy nrog 10% rhodium, 90% platinum, thiab dawb huv platinum rau qhov tsis zoo electrode (SN). Feem ntau hu ua tib platinum rhodium thermocouple. Lub sij hawm ntev ua haujlwm siab tshaj plaws ntawm qhov thermocouple no yog 1300ºƒ, thiab lub sijhawm luv luv ua haujlwm kub siab tshaj plaws yog 1600ºƒ.
