ABSTRACT:
A high temperature thermocouple sensing apparatus is readily removable from a gas turbine engine. The thermocouple extends through aligned openings in inner and outer housings and seals both openings through use of a pair of spherical sealing elements and a spring seal bellows urging a seat into sealing engagement with one sealing element and urging the other sealing element into engagement with the inner housing.
