摘要： A magnetic gas turbine sensor (25) for sensing the speed and/or torque of a shaft in a gas turbine engine, the sensor comprising a magnetically energisable pole piece (3), a magnet (2) associated with the pole piece and a conductive sensing element (4) wrapped or wound around the pole piece (3) and inductively coupled to the pole piece. The sensor includes a first sensor casing including a first inner fluid conduit (36) for fluid coolant, the first fluid conduit being inside the casing and running alongside and/or adjacent the pole piece, magnet and/or conductive sensing element, and the sensor also including a second sensor casing surrounding the first sensor casing and defining a second outer fluid conduit (37) for fluid coolant and at least partially surrounding the first fluid conduit. Fluid coolant may flow into the sensor at its proximal mounting end, through the first fluid conduit over or through the pole piece, magnet and/or conductive sensing element to the sensing end, and then through the second fluid conduit from the distal sensing end (29) to the outlet at the proximal mounting end (31).
In an alternative embodiment, a hollow conductive tube is used at the same time as the sensing element and as a coolant fluid conduit. The sensing tube is arranged to be part of a closed electrical circuit such that current can be induced in this circuit, and this closed circuit is magnetically coupled to a secondary coil, to form a transformer such that a current in the sensing circuit induces a voltage across the secondary coil.-

摘要： A sensing system for sensing rotational speed of a shaft in a gas turbine engine, comprising: a target, the target fixed to the shaft in use, the target comprising at least one ferrous target element radially spaced from the shaft, and a first magnetic probe assembly comprising a first pole piece element and a second pole piece element, wherein the first pole piece element and the second pole piece element are radially spaced from one another so that the at least one ferrous target element passes proximate to and between the first and second pole piece elements as the target rotates, so that radial movement of the at least one ferrous target element away from one of the first and second pole piece elements results in simultaneous and corresponding radial movement of the at least one ferrous target element towards the other of the first and second pole piece elements. By providing pole piece elements that are radially spaced from each other, radial movement of the target away from one pole piece element as a result of eccentric rotation of the shaft is compensated for by corresponding movement of the target towards the other pole piece element, so that the output signal remains stable.

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).
