ABSTRACT:
A tubular element having structural members disposed thereon at selected axial locations for supporting thermocouples inside the bore of a hollow shaft. Each of the structural members constitutes a generally "X"-shaped configuration which is substantially divided in half to form separated sections. Thermocouples placed in the legs of each X-shaped structural member are biased into contact with the shaft's interior surface by spring members which are disposed in openings formed in both sections on opposite sides of the X member's division at low or zero speed and by the springs and centrifugal force at high speed. Relative axial movement of the sections constituting each X member is restrained by dowels set into the sections and across the space separating them. Wires from the thermocouples extend radially into and axially within the tubular member. At one axial end of the tubular member the thermocouple wires are connected to a rotatable transmitter which broadcasts signals received from those thermocouples. A remote, stationary receiver provides indications of signals broadcast by the transmitter. Such indications can be correlated with temperatures and thus provide continuous temperature measurement at any circumferential and axial position within the hollow rotatable shaft.
