The OMEGA® Exotic Thermocouple Probes are built for use in extreme temperatures - up to 2315 °C (4200 °F). These probes utilize either tungsten/rhenium (types G, C, or D) or platinum/rhodium (types R, S, or B) elements, with various insulations and sheath materials.

Based on the sheath material chosen, these probes may be used in oxidizing, inert, reducing, or vacuum conditions. The highest temperature is based on the lowest maximum temperature of the element, sheath, and insulation material.

Five cold end probe terminations are available – subminiature or standard size ceramic connector, replacement probe, molybdenum-sheathed nylon connector, heavy-duty standard size, or transition joint with two-meter long lead wire.

Sheath Materials

*Refractory metals are highly sensitive to any trace of oxygen above roughly 260 °C (500 °F). Should be used in vacuum or in very pure inert gases such as argon or helium.

Insulation Materials

Note:

For temperatures over 1000 °C (1800 °F), all insulating materials undergo a considerable decrease in resistivity with increasing temperatures.

** Values provided are for compacted insulation. For uncompacted hard-fired insulators, practical temperature range can be 40 to 90 °C (100 to 200 °F) higher.

It is advised not to use molybdenum sheathed probes in applications where they might come into contact with carbon, including graphite.

Termination Style Q

Type OGP heavy-duty, color-coded male and female connectors.

Termination Style HX

Type NHX high temperature ceramic male and female connectors with color identification dot.

Termination Style RP

Replacement probe style with 25 mm long bare wire leads.

Termination Style SX

Type SHX tiny high temperature ceramic male and female connectors with color identification dot.

Termination Style TJ

Heavy-duty transition termination with 2-meter long leads.
