OMEGA
SPPL-025 Platinum-Rhodium Fine Diameter Bare Thermocouple Wire
Uninsulated, Fine Gage, Platinum-Rhodium Thermocouple Wire, Single Leg and Matched Pairs
For high resistance to oxidation and corrosion at high temperatures, OMEGA offers the highest quality uninsulated wire for three types of “noble metal” thermocouples.
They are:
Type S:
Platinum (–) vs.
Platinum 10% Rhodium (+)
Type R:
Platinum (–) vs.
Platinum 13% Rhodium (+)
Type B:
Platinum 6% Rhodium (–) vs.
Platinum 30% Rhodium (+)
Types R and S are recommended for continuous use in oxidizing or inert atmospheres up to 2550°F (1398°C) or short term exposures to 2700°F (1482°C). Type B is rated for continuous use up to 3100°F (1704°C) in oxidizing or inert atmospheres. When operating near these maximum temperatures, the heavier gage wire sizes are recommended.
All three thermocouple types can be used in a vacuum for short periods of time. Type B offers greater stability in such applications. None should be used in reducing atmospheres or in atmospheres containing metallic or non-metallic vapors unless protected by non-metallic protection tubes. Do not insert directly into metallic protection tubes.
• Ordering unit of measure is double inch, which is 25mm (1') of positive and 25mm (1') of matching negative wire
• Available as Single Legs and as Matched Wire Pairs
• Type R and S Temperature Ranges from 1398 to 1482°C (2550 to 2700°F)
• Type B is rated for continuous use up to 1704°C (3100°F)
