Description

Find how a Thermocouple wire works on this link.

For high resistance to oxidation and corrosion at high temperatures, OMEGA offers the highest quality uninsulated wire for three types of "noble metal" thermocouples:

Type S:
Platinum (-)
Platinum 10% Rhodium (+)

Type R:
Platinum (-)
Platinum 13% Rhodium (+)

Type B:
Platinum 6% Rhodium (-)
Platinum 30% Rhodium (+)

Types R and S are recommended for continuous use in oxidizing or inert atmospheres up to 1400°C or short term exposures to 1480°C. Type B is rated for continuous use up to 1700°C in oxidizing or inert atmospheres. When operating near these maximum temperatures, the larger diameter 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 vapours unless protected by non-metallic protection tubes. Do not insert directly into metallic protection tubes.

Sizes range from 0.025 to 0.81 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.

Insulated duplex extension grade wire for types R, S, and B is also available. See, for example, model numbers EXGG-RS, EXTT-RS, EXPP-RS in the table below.
