A turbine assembly includes a bladed rotor mounted for rotation about an axis of the gas turbine engine, a case assembly, and a tip clearance system. The tip clearance system includes a tip clearance sensor located in an annular plenum defined between an inner case and an outer case included in the case assembly. The tip sensor is configured to monitor a tip clearance formed between the bladed rotor and the case assembly during operation of the gas turbine engine.

A turbine engine may include a compressor section of the turbine engine. The turbine engine may include a combustion section of the turbine engine. The combustion section may be downstream of the compressor section. The turbine engine may include a turbine section of the turbine engine. The turbine section may be downstream of the combustion section. The turbine engine may include a sensor for speed detection. The sensor may be disposed at an upstream segment of the turbine section. The sensor may include a cooling jacket. The cooling jacket may encase at least a portion of the sensor. A cooling fluid may be in fluid communication with the cooling jacket and an outer surface of the sensor. The cooling jacket may be shaped to direct cooling fluid around the sensor.
