Abstract

A backing sensor (7) for use with a gas turbine to detect abnormal turbine shaft motion. The backing sensor has an elongate frangible sensor element (10) and a cutter coupled to and moveable with the turbine shaft to break or cut through the frangible sensor element (10) on axial movement of the shaft. The frangible sensor element (10) comprises mineral insulated cable having an elongate metal sheath enclosing an insulating mineral powder (17) and conductive wires (9) running inside and substantially parallel to the longitudinal axis of the sheath. The wires (9) are welded, brazed or soldered together at the distal end of the sensor element (18) to define a single continuous conductive path running from the proximal end of the frangible sensor element (10) to its distal end and then back to its proximal end.
