Claim 15:
16. A method of cooling a sensor for detecting the speed of a surface of a turbine section in a turbine engine, the method comprising:
starting and rotating the turbine engine, the sensor disposed at a upstream segment of a turbine section of the turbine engine, and a cooling jacket disposed at least partially around the sensor, wherein an inner cross sectional area of the cooling jacket being larger than an outer cross sectional area of the sensor;
directing cooling fluid through the cooling jacket, the cooing fluid cooling an outer surface of the sensor; and
directing the cooling fluid out of the cooling jacket through a hole disposed 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.
