The bearings of industrial rotating equipment operate under arduous conditions—often for considerable periods of time. The most reliable indicator of bearing condition is the temperature of the metal beneath the shoe. Recognition of rising temperature can provide a warning of the breakdown of the lubricating oil film, allowing machine shutdown and maintenance to take place before catastrophic failure of the bearing and possible damage to its mounting. Conax Miniature Bearing Sensors provide a simple and cost-effective method to monitor bearing temperatures.

These sensors are for embedded applications where temperature monitoring is critical to machine performance and reliability. The unique bearing sensor wire seal prevents migration of oil along the sensor leads. Available with RTDs or thermocouple types J, K, T and E.

Conax Technologies’ thermocouples for this application meet the operational and performance requirements, per the OEM specifications, as replacements on heavy duty gas turbines. These cost-effective thermocouples are hermetically sealed to provide a more reliable product that eliminates IR failures. The positive stop at the tip of the thermocouple eliminates any fretting problems. Our wheelspace, disc cavity and CDT thermocouples are manufactured using a stainless steel sheath and MgO insulation with type K conductors to ensure the robust design needed in this application.

All specification-qualified thermocouples are manufactured from ASTM E585 thermocouple material using the highest purity insulation material to yield superior insulation resistance at elevated temperatures. The thermocouples are manufactured and tested at various points during the manufacturing cycle, ensuring the highest possible level of quality. Production testing includes helium leak testing, calibration, thermal shock, insulation resistance, and hermeticity testing of sealing points.

These type K ungrounded thermocouples are manufactured using Special (+/-0.4%) limits and have a time response of 1.7 to 4.0 seconds, depending on the tip configuration. Conax Technologies manufactures these exhaust thermocouples with tip diameters from .062 diameter to .125. They are used on all heavy-duty gas turbines and are of the latest configuration for easy replacement. Just connect our thermocouple to the flexible, stainless steel braided cable for quick installation and longer life.

All specification-qualified exhaust gas and blade path thermocouples are manufactured from ASTM E585 thermocouple materials utilizing the highest purity insulation material yielding superior insulation resistance at elevated temperatures.

The thermocouples are manufactured and tested at various points during the manufacturing cycle to ensure the highest possible level of quality. Product testing includes helium leak testing, calibration, thermal shock, insulation resistance and hermeticity testing of sealing points.

Featuring Type K conductor wire with MgO insulation, these sensors are hermetically sealed in stainless steel for high-temperature oxidation resistance and feature vibration-resistant hermetic terminations and high-reliability mineral insulated cable.

Conax works directly with industry leaders to custom design, build, test, and deliver high-quality cable and harness assemblies for a wide variety of engines and applications, including:

  • Cable assemblies for large frame ground-based turbines
  • Cable and harness assemblies for ground-based aeroderivative engines
  • Mineral insulated cable

The Quality Management System of Conax Technologies has been assessed by NSF-ISR, and Conax was the first in the industry to receive AS9100D certification.

Our patented Spring Loaded Exhaust Gas Sensors eliminate premature sensor failures

Standard exhaust gas sensors in 7F and 9F class turbines are at risk of premature failure due to vibrations caused by gas flow velocities, input vibrations and thermal expansion mismatch.

Conax Technologies’ exclusive Spring Loaded Exhaust Gas Sensors are specially designed to withstand these vibrations and avoid premature sensor failures.

Our patented sensors have a high temperature compression spring that’s inserted between two spacer tubes. The spring dampens the vibration and keeps the temperature sensor tip seated within the radiation shield. With this increased stability, the sensor tips won’t break. So turbines run longer without the risk of premature sensor failure.
