EGT Thermocouples

AMETEK Sensors & Fluid Management Systems (SFMS) designs and manufactures exhaust gas temperature (EGT) thermocouples for high-temperature aircraft engine applications. Installed in the engine, these sensors provide accurate EGT measurements used to monitor engine performance and operating margin.

Engineered for extreme heat, vibration, oxidation, erosion, and mechanical creep, SFMS EGT thermocouples combine high-accuracy conductors with rugged probe construction, and each configuration is tailored to the engine application.

• Accurate EGT measurement supports precise engine operating conditions.
• High-temperature construction withstands demanding turbine environments.
• Probe design provides superior creep and oxidation resistance.
• Custom probes, cables, harnesses, and rake configurations support program-specific requirements.

SFMS applies specialized material selection, swaging, bending, brazing, welding, X-ray, and scanning electron microscope inspection capabilities to produce dependable thermocouple assemblies for commercial, military, rotorcraft, and aeroderivative engines.

Our EGT probe designs use advanced support and materials to improve resistance to mechanical creep, oxidation, and probe erosion. Consistent in-house manufacturing and calibration help support reliable performance across the complete EGT sensing system.

Benefits

• Accurate EGT margin measurement supports longer engine time on wing.
• High-temperature materials improve durability and service life.
• Robust construction resists creep, oxidation, erosion, and vibration.
• Single-source probes, cables, and harnesses provide consistent system quality.
