These probes utilize either Platinum/Rhodium (TYPE R, S, or B) or Tungsten/Rhenium (TYPE C or D) elements and a variety of insulations/sheath materials. Depending on the sheath material selected, probes can be used in inert, oxidizing, reducing or vacuum conditions. The maximum temperature of the final assembly is based on the lowest maximum temperature of the element, insulation and sheath material. - 1.For Type C and D, ANSI color codes are used as there is no IEC standard. - 2.Images throughout spec sheet are for reference only. - 3.Non-Metallic sheaths are available. Please see PTRA and PTRM ceramic thermocouple protection tubes at Omega. Cold end probe terminations are available in: replacement probe (RP), standard or subminiature ceramic connector, standard or subminiature heavy-duty nylon connector, or transition joint with 2 m (72”) braided fiberglass lead wire. Other options available on page 3/4 or contact sales. ## Part number Breakdown / Example ## **XMO - W5R26 - U - 125 - 30 - A - Q - 12 - Dual** |e **1 2 3 4** a **5 6 7** [ez **8 9** 1.
