Abstract
A sensor guide tube for bridging a plenum between a turbine housing and a nozzle assembly includes an offset portion whose offset is substantially equal to half the distance which the nozzle assembly is displaced upstream for clearance restoration. After clearance restoration, the guide tube is rotated 180 degrees to align its lower end with an opening in the nozzle assembly without requiring a sharp bend in the axis of the sensor guide tube.
