PtRh13-Pt R-Type Thermocouple Ultra-Precise High-Temp Sensing & Karabelo e tsitsitseng ea Thermo
Tlhaloso ea Sehlahisoa
Mofuta oa R Thermocouple Wire
Kakaretso ea Sehlahisoa
Mofuta oa R oa thermocouple terata ke tšepe ea bohlokoa e phahameng ea boleng bo phahameng e entsoeng ka platinum-rhodium 13% alloy (leoto le letle) le platinum e hloekileng (leoto le fosahetseng). Ke ea lelapa la platinum-rhodium thermocouple, e fanang ka botsitso bo phahameng le ho nepahala libakeng tse phahameng tsa mocheso, haholo-holo ho tloha ho 1000 ° C ho isa ho 1600 ° C. Ha e bapisoa le mofuta oa S thermocouples, e na le lihlahisoa tse phahameng tsa rhodium leotong le letle, tse fanang ka ts'ebetso e ntlafetseng lits'ebetsong tsa nako e telele tsa mocheso o phahameng.
