Abstract
An arrangement for sensing temperature in an interstage cavity 24 comprises an extractable temperature probe 44 having a radially inner end sensing portion 46 disposed in a bore 40 in a seal housing 22, the bore 40 receiving bypassing fluid flow which enters the bypassing passage 34 from a location intermediate the axial extent of a sealed leakage path 32 between the upstream and downstream regions 24a and 24b, respectively, of the interstage cavity. These components collectively form the self-aspirating disc cavity seal temperature measuring system.
