Beskrivelse

OMEGA™ Exotic Thermocouple Probes are designed for use in extreme temperatures, up to 2315°C (4200°F). These probes utilize 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, oxidizing, 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, molybdenum-sheathed nylon connector, or transition joint with 2 metre long lead wire.

Sheath Materials

Code	Material	Max. Operating Temp.	Working Environment	Approx. Melting Point	Remarks
XTA	Tantalum	2300°C 4200°F	Vacuum	3000°C 5425°F	Resists Many Acids and Weak Alkalies. Very Sensitive to Oxidation Above 300°C
XMO*	Molybdenum	2200°C 4000°F	Inert Vacuum Reducing	2610°C 4730°F	Sensitive to Oxidation Above 200°C Non-bendable
XPA	Platinum- Rhodium Alloy	1650°C 3000°F	Oxidizing Inert	1870°C 3400°F	No Attack by SO2 at 1100°C. Silica Is Detrimental. Halogens Attack at High Temp.
XIN	Inconel 600	1150°C 2100°F	Oxidizing Inert Vacuum	1400°C 2550°F	Excellent Resistance to Oxidation at High Temp. Hydrogen Tends to Embrittle. Very Sensitive to Sulphur Corrosion

*Refractory metals are extremely sensitive to any trace of oxygen above approximately 260°C
(500°F). Must be used in vacuum or in very pure inert gases such as Hellium or Argon.

Insulation Materials

Code	Material	Max. Operating Temp.**	Approx. Melting Point	Remarks
H	Hafnia (HfO₂)	2500°C 4530°F	2830°C 5125°F	Nontoxic substitute for BeO. High Thermal Conductivity.
M	Magnesia (M_gO)	1650°C 3000°F	2790°C 5050°F	Hygroscopic. Compacts Well.
A	Alumina (Al₂O₃)	1540°C 2800°F	2010°C 3650°F	Requires Considerable Volume Reduction to Compact Satisfactorily.

Note:
For temperatures above 1000°C (1800°F), all insulating materials experience a
substantial decrease in resistivity with increasing temperatures.

** Values given are for compacted insulation. For uncompacted hard-fired insulators,
useful temperature range can be 40 to 90°C (100 to 200°F) higher.
Molybdenum sheathed probes are not recommended in applications where they will be
exposed to carbon, including graphite.

For Graphite environments, Consult Omega's Sales Department for Pricing and Delivery on Tungsten Coated Molybdenum sheathed T hermocouples.
