What is the function of the ITT gauge?

The ITT gauge, or Interstage Turbine Temperature gauge, serves a critical function in monitoring the temperature between the turbine stages in a gas turbine engine. Specifically, it measures the temperature of the gases as they pass through the turbine. This measurement is essential for ensuring that the engine is operating within safe and efficient temperature limits. High temperatures can indicate potential issues such as overheating or malfunction, which could lead to damage or failure; thus, monitoring the ITT is crucial for safe operation.

Maintaining the appropriate inter-stage turbine temperature allows for optimal performance and longevity of the engine components. In the context of engine performance, understanding the temperature dynamics helps engineers and pilots make informed decisions during flight operations.
