INSTALLATION IS KEY

It’s time to replace the most important sensor in your gas turbine

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 (TCs) are a priority for every operator.

Have you had trouble getting your exhaust TC 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 TC.

MORE RELIABLE, EASIER MAINTENANCE

The advantages of replacing your gas turbine’s thermocouples

Replacing your gas turbine’s exhaust thermocouple will result in more accurate exhaust gas temperature sensor readings, which will in turn help increase the life of your TC and all associated parts. If for any reason the new TC 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 TC needs to be replaced—no need to also replace the cabling from the radiation shield to the junction box.

The latest stud-type TC is engineered to fit your unit

The configuration of the latest stud-type TC addresses the main issue with previous models: Human error. Because the TC 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 overtightening the fitting. With proper installation, not only will you prolong the life of your TC, 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.
