Thermocouple Probes XTA, XMO, XPA, XIN Series - 1

32 Exotic Thermocouple Probes OMEGATM Exotic Thermocouple Probes are designed for use in extreme temperatures, up to 2315°C. These probes use either Platinum/ Rhodium (types R, S, or B) or Tungsten/Rhenium (types G, C, or D) elements, with a variety of insulations and sheath materials. Depending upon the sheath material selected, these probes may be used in inert, oxidising, reducing or vacuum conditions. The maximum temperature is based on the lowest max. temperature of the element, insulation and sheath material. Five cold end probe terminations are available: replacement probe, subminiature or standard size ceramic connector, heavy-duty standard size, nylon connector, or transition joint with 2 m lead wire.

Sheath Materials Insulation Materials Note: For temperatures above 1000°C, all insulating materials experience a substantial decrease in resistivity with increasing temperatures. * Molybdenum and Tantalum sheathed probes are not recommended in applications where they will be exposed to carbon, including graphite. ** Values given are for compacted insulation. For uncompacted hard-fired insulators, useful temperature range can be 5 to 110°C higher. Standard Connector Standard Connector (Cold end temperature is rated to 100°C max) Shown smaller than actual size. Miniature Connector † Non-metallic sheaths are also available. Please see PTRA and PTRM ceramic thermocouple protection tubes on omega.co.uk Note: For Type G, C and D, ANSI Colour Codes are used as there is no IEC standard. Refractory metals are extremely sensitive to any trace of oxygen above approximately 260°C. Must be used in vacuum or in very pure inert gases such as Helium or Argon. For Measuring Temperatures up to 2315°C
