Supported Applications

The Omega™ XTA exotic thermocouple probes are designed for extreme-temperature measurement up to 2315 °C (4200 °F). They use either Platinum/Rhodium elements (Type R, S, or B) or Tungsten/Rhenium elements (Type C or D) with a range of insulation and sheath materials, making them suitable for high-temperature process work in inert, oxidizing, reducing, or vacuum conditions.

Because refractory metals are extremely sensitive to any trace of oxygen above approximately 260 °C (500 °F), the tungsten/rhenium sheath options must be used in vacuum or in very pure inert gases such as helium or argon.

Operating Conditions & Performance

The probes measure temperatures up to 2315 °C (4200 °F), with the maximum temperature of the final assembly set by the lowest-rated of the element, insulation, and sheath materials. All probes are ungrounded.

  • Element / calibration: Platinum/Rhodium (Type R, S, B) or Tungsten/Rhenium (Type C, D), via calibration codes such as W5R26, W3R25, P10R, P13R, and P30R.
  • Sheath materials: Tantalum, Molybdenum, Platinum-Rhodium alloy, or Inconel 600.
  • Sheath diameters: 0.062 in (1/16 in), 0.125 in (1/8 in), 0.187 in (3/16 in), and 0.250 in (1/4 in).
  • Media: vacuum, inert, oxidizing, or reducing atmospheres, per the selected sheath.

Optional compression fittings allow fast mounting and positioning, and dual-element assemblies provide two sensor readings for built-in backup or for sending signals to different instruments.

Configuration Options

Part numbers follow an ordering-guide breakdown of sheath-material code, calibration code, junction, sheath diameter, wire gauge, insulation code, termination style, length, and single/dual element. Configuration axes include:

  • Junction: ungrounded (U).
  • Termination styles: Q, HX, SX, TJ, RP, MQ, TJ-BX, TJ-SB, and NB1/NB12.
  • Length: 1" to 48" in 0.5" increments (to 100" for selected constructions).
  • Element count: single or dual element.

Tungsten/rhenium probes can be tungsten-coated when required for additional protection.

Key Product Differences

The series covers the platinum/rhodium and tungsten/rhenium calibrations across the sheath, diameter, termination, and length options. Representative catalog numbers include:

  • XMO-W5R26-U-125-30-A-Q-12
  • XMO-W5R26-U-125-30-A-SX-8
  • XMO-W5R26-U-062-36-H-SX-4

Specify sheath-material code, calibration, junction, sheath diameter, wire gauge, insulation, termination style, length, and single/dual element to define a complete probe.
