For high resistance
to oxidation and corrosion at high temperatures, NEWPORT 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% Rhod36ium (+)
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.
Sizes range from 0.001 to 0.032" (0.025 to 0.812 mm) diameter. When
requested, wire is supplied in matched pairs which meet or exceed standard
limits of error. Special-limits-of-error wire is supplied on request
and must be ordered as matched pairs.
