Immersion Thermocouples provide single point or multiple points of temperature measurement in the gas stream of a turbine engine. Utilizing the latest alloys for strength, oxidation resistance, and extended service life, immersion thermocouples can be configured with male or female terminals, high temperature flexible cables with terminal lugs, or connectors to achieve hermetic sealed construction. Tip configurations have been designed to enhance time response, minimize flow path disturbance, and maximize service life in the most demanding operating environments.
