ABSTRACT:
A sensing device for protecting a sensor from environmental conditions present in a turbine is provided. The sensing device comprises a heat pipe exposed to the environmental conditions for protecting the sensor from these conditions. The sensing device further comprises a sensor located in a center channel of the heat pipe and a working fluid located in an annulus of the heat pipe to aid in regulating heat along the length of the heat pipe. In alternate embodiments, the sensing device further comprises power wires extending from a power source outside the turbine to the sensor for supplying power to the sensor, and signal wires extending from the sensor to a data acquisition system outside the turbine for transmitting readings from the sensor to the data acquisition system.
