AIRCRAFT BRAKE ASSEMBLY SENSING DEVICE

The present invention relates to a sensing device 10 for monitoring aircraft brake assemblies, in particular the sensing device is for monitoring wear and/or temperature of the aircraft brake assembly. The device comprises a housing 14 rigidly connected to the chassis of the aircraft brake assembly, wherein the housing comprises a displacement sensor 26. The device further comprises a pin 12, 15, 16 extending through the housing with a first end 22 configured to move with a pressure plate 18 of the aircraft brake assembly such that, in use, the pin is configured to move relative to the housing 14 in a longitudinal direction of the pin. The pin comprises a detectable element 28 positioned within the housing, and the displacement sensor 26 is configured to monitor the position of the detectable element 28 within the housing. The present invention also extends to an aircraft brake assembly comprising the sensing device, and a method of monitoring wear and/or temperature using the sensing device.
