1. A turbine engine comprising:
a compressor section of the turbine engine;
a combustion section of the turbine engine, the combustion section downstream of the compressor section;
a turbine section of the turbine engine, the turbine section downstream of the combustion section; and
a sensor for detecting the speed of a surface of the turbine section, the sensor disposed at an upstream segment of the turbine section,
wherein the sensor includes a cooling jacket surrounding the sensor, the cooling jacket including an opening at an end of the cooling jacket disposed within the turbine section of the turbine engine for discharging cooling fluid adjacent to the surface of the turbine section from a radially innermost end of the cooling jacket.
