Conax Technologies’ hermetically designed exhaust gas thermocouple has been fully tested to OEM specifications. This 100% hermetic thermocouple also has the latest more compatible materials to help eliminate open circuits during start up, thus eliminating false turbine trips and inconvenient and expensive down times. Our new exhaust gas thermocouple has been subjected to rigorous qualification 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, passing all OEM qualification tests and meeting all design specifications required by the OEM. Our unit is manufactured with an all welded construction that is superior to brazing in prolonging the life of the thermocouple. This thermocouple is a direct replacement for all other exhaust gas thermocouples on Frame turbines, whether you are replacing or upgrading your equipment. They can be purchased directly from Conax Technologies to lower your total costs.
Superior Quality
These type K ungrounded thermocouples are manufactured using conductor materials meeting special limits of error (± 0.4% accuracy), and have a time response of 2.9 seconds. All specification qualified exhaust gas thermocouples are manufactured per ASTM standards utilizing the highest purity insulation materials yielding superior insulation resistance at elevated temperatures. Conax 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.
Precise Installation
Conax exhaust gas thermocouples are designed to ensure proper installation every time. The bushing at the sensing end of the thermocouple seats firmly into the radiation shield allowing the junction to be in the proper position, giving you the optimum response time and accurate temperature measurement. The bushing is also fabricated of materials that reduces the possibility of seizure in the radiation shield. The cold end features a ceramic filled connector housing with a two pin hermetic sealed connector. The individual connector pins are made of KN and KP materials. This allows a homogeneous temperature measurement when applying the mating cables.
Technical Sales Support
Whether you are upgrading or replacing your exhaust 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 372A2221 exhaust gas thermocouple.
