Conax Technologies’ hermetically designed wheelspace thermocouple has been eld tested and proven to be a very reliable
product for Frame turbine applications. Our wheelspace thermocouple has been subjected to rigorous qualication tests including
vibration testing to 10 million cycles of simulated on turbine operation, thermal cycling the measuring tip 20,000 times between
1220°F and room temperature, and thermal cycling the hermetic terminal head 600 times between 700°F and -65°F. Our wheelspace
thermocouple has passed all OEM qualication tests and meets all design specications required by the OEM. This thermocouple is a
direct replacement for all other wheelspace thermocouples on Frame turbines, whether you are replacing or upgrading your equipment,
and can be purchased directly from Conax Technologies lowering your total costs.

These type K ungrounded thermocouples are manufactured using conductor materials meeting special limits of error (+/- 0.4% accuracy)
for improved accuracy. All specication qualied wheelspace thermocouples are manufactured per ASTM standards utilizing the highest
purity insulation materials yielding superior insulation resistance at elevated temperatures. In our factory, Conax’s thermocouples are
manufactured and tested at various points during the manufacturing cycle to give you the highest possible level of quality. The testing
includes helium leak testing of sealing points, calibration, thermal shock and insulation resistance.

Conax’s wheelspace thermocouple is designed to ensure proper installation every time and the installation is easy. The thermocouple is
inserted into a guide tube until it is bottomed out allowing the junction to be in the proper position to provide you the optimum response
time and accurate temperature. The cold end features a ceramic insulated junction box using two dierent size studs to guarantee
proper installation every time. It also enables a convenient, stress-free orientation of the thermocouple junction box as it relates to the
mating cable by using a compression tting.

Whether you are upgrading or replacing your wheelspace thermocouples, Conax Technologies’ Technical Team can help you solve your
problems. We can help you upgrade from using the one piece design such as the 302A4010Pxxx or 351A3488Pxxx or if you just need to
replace a 361A2289 wheelspace thermocouple. Call our inside Sales Team at (02) 2678-0667 dailibc@dailibc and you’ll get the support you need to make the right choices.
