Thermocouple Feedthroughs

Morgan Technical Ceramics manufacture ceramic-to-metal thermocouple feedthroughs and connectors designed for high performance and reliability whilst operating in harsh and ever increasingly demanding environments.

Our thermocouple feedthroughs are hermetic and designed to incorporate matched thermocouple terminal materials to ensure continuity of signal. We also supply high performance metallised ceramics for our customers to braze into their own thermocouple connectors.

Thermocouple Feedthroughs Applications

Our thermocouple housings, headers and fire detection feedthroughs can handle extreme conditions while remaining specialised for individual tasks. Constructed from corrosion resistant metal components and high purity alumina ceramic, brazed together to produce stable hermeticity in severe environments. They are resistant to vibration and mechanical shock failure, making them well suited for aircraft engine applications.
