Rolls-Royce LW100346 Thermocouple T455 K-Type

The Rolls-Royce LW100346 Thermocouple T455 K-Type, also identified by Part Numbers 106544633 and 753-11-36, is a precision aviation sensor designed to measure and monitor temperature within turbine engine systems. Thermocouples play a vital role in engine performance monitoring by providing accurate temperature data used for engine control, protection, and diagnostic functions.

This component utilizes K-Type thermocouple technology, which is widely used in aerospace applications due to its stability, wide temperature range, and resistance to harsh operating environments. The T455 configuration is engineered to deliver consistent and reliable temperature readings under high thermal loads, vibration, and continuous operational cycles common in turbine engines.

Manufactured to the engineering and quality standards associated with Rolls‑Royce engine systems, the LW100346 thermocouple is designed for precise fitment and dependable performance in approved engine applications. Accurate temperature measurement is critical for monitoring exhaust gas temperature (EGT), turbine inlet temperature, or other critical engine parameters that directly affect engine health and operational safety.

The thermocouple is commonly installed during scheduled maintenance, troubleshooting of engine indication systems, or engine overhaul activities. Proper functioning of the thermocouple supports effective engine control, helps prevent over-temperature conditions, and contributes to extending engine component life by enabling timely maintenance actions.

Part numbers 106544633 and 753-11-36 identify approved configurations and traceability for this thermocouple, making it suitable for use in certified aviation maintenance environments, including MRO facilities and fleet operations. Installation and evaluation should be performed by qualified personnel in accordance with applicable engine manuals and regulatory requirements.

The Rolls-Royce LW100346 Thermocouple T455 K-Type is intended strictly for aerospace use, where measurement accuracy, durability, and component traceability are essential for safe and reliable turbine engine operation.
