摘要： The present invention provides a system for detecting abnormal axial movement of a shaft in a gas turbine engine. The system comprises a detection circuit including a detector element including a frangible link portion (32) forming part of an electrical detection circuit and a plunger (38) integral with the frangible link portion (32). The plunger (38) is arranged such that it is displaced by abnormal axial movement of the gas turbine shaft to break the frangible link portion (32) from the remainder of the detection circuit and thereby break the electrical detection circuit. The system includes two connection blocks (33, 35) each having a connection at a respective first portion for electrical connection to a signal sensing unit, and being connected at respective second portions to opposite ends of the frangible link portion such that the electrical circuit running through the detector element and a signal sensing unit is modified when the frangible link portion (32) is broken by movement of the plunger (38).
