摘要： The invention comprises a variable reluctance sensor for sensing the speed or torque of a shaft in a gear box or gas turbine engine, comprising a magnetic pole piece; a conductive wire wrapped around the pole piece; a housing surrounding the pole piece, the housing having a front face and at least one side wall, wherein, in use, the front face is positioned proximate to an object to be sensed, wherein the pole piece extends through the front face of the housing and the front face of the housing is substantially less rigid than the side wall of the housing by forming the front face substantially thinner and less massive than the sidewalls of the housing. By having a front face that is able to flex, less stress is exerted on the pole piece under external vibration, when the pole piece is firmly connected to the front face.

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).

摘要： A sensor element for use in a backing sensor to monitor a gas turbine shaft. The sensor includes an oscillator circuit (30) having an oscillator and a resonance circuit (42), and a frequency detector (31) for monitoring the frequency of the ossilation circuit. Abnormal movement of the shaft cuts the circuit in the sensor along a cutting line (15). The cutting of the sensor changes the capacitance and/or inductance of the resonance circuit and thereby changes the frequency of oscillation.

摘要： A cooled thermocouple arrangement (1) including a thermocouple (2) comprising two wires (3,4) joined at a first sensing end (5) to define a hot thermocouple function. At least a portion of the wires (3,4) are in thermal communication with a cooling arrangement, and the cooling arrangement has an inlet (14) for coolant and an outlet (15) for coolant. The thermocouple probe arrangement (1) includes a first inlet temperature sensor (21) for determining the temperature of the coolant as it enters the cooling arrangement, and a flow rate sensor (20) for determining the flow rate of coolant passing through the cooling arrangement. The thermocouple probe arrangement (1) includes connectors for connecting the outputs from the thermocouple (2), first inlet temperature sensor (21) and the flow rate sensor (20) to a correction data processor (23) whereby the data processor can correct the temperature sensed by the thermocouple to take account of the effect of the cooling arrangement. The pair of thermocouple wires (3,4) are arranged inside a sheath or casing, and a cooling jacket (12) is provided around the thermocouple probe. The cooling jacket (12) includes a pair of concentric tubes (16,17) defining a return coolant circuit from the end of the probe proximal the connectors (8), to a portion of the probe distal from the connectors, and then back to the proximal end (8) of the probe, and the portion of the thermocouple probe containing the sensing end (5) of the thermocouple projects from the distal end of the cooling jacket (12).

摘要： The invention provides a total gas temperature sensor for measuring the temperature of gas in a gas flow. A gas temperature sensor in accordance with the invention comprises a measurement chamber having a gas inlet and a gas outlet; an outlet valve located at the gas outlet, operable to seal the gas outlet when in a closed position, and a temperature sensing element located in the measurement chamber. The sensor is simple to manufacture, is robust, provides for a low recovery correction and does not suffer from significant boundary layer problems.

摘要： An inductive eddy current sensor, for use for example for measuring the speed of a turbine by detecting the passage of turbine blades (21) past a probe incorporating the sensor, includes a magnet (23) positioned so that the blades (21) pass through the flux pattern generated by the magnet (23). At least one pick-up coil (28) devoid of a core of soft magnetic is positioned alongside the magnet to pick up signals generated by eddy currents generated in the turbine blades as they cut through the flux pattern, without thereby altering the flux pattern. In a modified arrangement, the pick-up coil surrounds the magnet, again without affecting the flux pattern.
