Improved reliability, proven experience
Replace your existing exhaust thermocouples for more accurate exhaust gas temperature sensor readings, longer asset life, and reliable operations.
Accurately measuring the temperature of your gas turbine’s exhaust gases is critical to the unit’s performance. In fact, it is possibly the most important measurement in the gas turbine. Thus, reliable and robust exhaust thermocouples are a priority for every operator.
Have you had trouble getting your exhaust thermocouple to seat properly? Or have you experienced limitations from exhaust spread? If so, it’s a good time to plan for a replacement with the latest, most accurate exhaust thermocouple.
What are the advantages of replacing your gas turbine’s thermocouples? You’ll have more accurate exhaust gas temperature sensor readings, which will in turn help increase the life of your thermocouple and all associated parts. If for any reason the new thermocouple needs to be replaced in the future, it’s a quicker and easier process because of the way it’s engineered: A single, connected shield means that only the thermocouple needs to be replaced—no need to also replace the cabling from the radiation shield to the junction box.
50% fewer parts need to be replaced
Avoid damage to your thermocouple
Installation time is reduced by up to 50%
In the last three years, our solution could have avoided as many as 130 unplanned outages
The new stud type thermocouple is installed on >100 of our units globally
The configuration of the latest stud-type thermocouple addresses the main issue with previous models: Human error. Because the thermocouple tip is a standard length that will fit your turbine, there’s no guesswork in making sure it’s properly seated and installed in the radiation shield, and no risk of over-tightening the fitting. With proper installation, not only will you prolong the life of your thermocouple, you will have a correct reading that provides insights into any anomalies with your combustion operation.
The studded thermocouple is the result of a three-year development program initiated to further improve exhaust thermocouple engineering and significantly reduce the maintenance hours needed to replace the thermocouple in the field.
Key features of the studded thermocouple:
Replacing your hydraulically actuated gas valves and inlet guide vane actuator with electrically actuated gas valves can help ensure long-term system safety and improve the reliability of your gas turbine and accessories.
GE’s valve tracking logic for trip mitigation is an application software enhancement developed to improve TMR robustness and mitigate the risk of unit trip.
An alternative to carbon steel valves, our stainless-steel compressor bleed valve can improve the reliability and availability of your gas turbine's critical cooling and sealing air system.
GE's latest generation ESM (Exhaust Spread Monitor) improves running reliability, resulting in longer response times to tackle thermocouple faults, along with increased uptime and fewer trips due to more robust handling of failures.
GE’s non-optical flame detector keeps a close watch on combustor operations for the balance of your plant. Get rid of outdated sensors and avoid risky flame failures.
