Conax Technologies’ exhaust and wheelspace thermocouples used on older Frame turbines meet or exceed the operational and
performance requirements required by the OEM specications on heavy duty gas turbines. These cost eective thermocouples are
designed to be hermetically sealed to provide a more reliable product that eliminates insulation resistance problems experienced when
using other supplier’s products. This robust design can accommodate either single or dual element thermocouples depending on your
application. The typical applications for these thermocouples include wheelspace, exhaust, compressor discharge, as well as others.

This hermetic thermocouple is a type K thermocouple with MgO insulation and stainless steel sheathing. It is also a direct replacement
for all older wheelspace, CDT, and exhaust thermocouples on Frame turbines manufactured prior to 1999. When replacing your
thermocouples, you can purchase directly from Conax Technologies to lower your total costs.

These type K ungrounded thermocouples are manufactured using conductor materials meeting special limits of error (± 0.4% accuracy),
or standard limits of error (± 0.75% accuracy), depending on the application. All Conax specication qualied thermocouples are
manufactured per ASTM E585 and ASTM E608 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, calibration, thermal shock
and insulation resistance.

When you are replacing your 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 if you just need to replace a 351A3488Pxxx thermocouple.
