  • Patent number: 10428680
    Abstract: The present invention relates to a system (100, 300, 400) for detecting abnormal movement of a gas turbine shaft. The system comprises: a magnetic circuit (104, 302, 402) comprising a first magnetic portion (110, 304) and a second portion (112, 404), and including at least one air gap between the first portion and the second portion; and a detection coil (106) wound around the first magnetic portion. The second portion is coupled to or moveable with the shaft to reduce the air gap, on axial movement of the shaft to change the reluctance of the magnetic circuit and thereby induce a voltage in the coil. The system may comprise a controller (108) for shutting off power to the gas turbine when the induced voltage exceeds a threshold voltage.

  • Patent number: 10386170
    Abstract: An angle sensor includes detection units and an angle computation unit. The detection units detect a composite magnetic field of a magnetic field to be detected and a noise magnetic field. Each detection unit generates a first detection signal representing the strength of a component in a first direction of the composite magnetic field, and a second detection signal representing the strength of a component in a second direction of the composite magnetic field. The angle computation unit generates a detected angle value by performing computations using a plurality of pairs of first and second detection signals generated at the detection units wherein an error of the detected angle value resulting from the noise magnetic field is made smaller than in the case of generating the detected angle value on the basis of only a pair of first and second detection signals generated at any one of the detection units.

  • Patent number: 10330498
    Abstract: In one embodiment, a sensor arrangement for the contactless sensing of angles of rotation on a rotating part includes a disk-shaped target, a coil arrangement, and an evaluation and control unit. The disc-shaped target is coupled to the rotating part and includes at least two metal surfaces that influence the inductances in the flat detection coils due to eddy current effects as a function of the degree of overlap. The disc-shaped target can generate at least one piece of information for ascertaining the instantaneous angle of rotation of the rotating part, in connection with the coil arrangement. The coil arrangement has three flat detection coils uniformly distributed on the circumference of a circle. The evaluation and control unit can generate essentially sinusoidal evaluation signals which represent the changes in inductance of the detection coils and can evaluate them for calculating the angle of rotation.

  • Patent number: 10330499
    Abstract: An inductive sensor includes a sensor package and a coupler package. The sensor package includes a signal processor, an integrated capacitor, a ferrite layer, a transmitter coil, a two part receiving coil, and a plurality of discrete components. The coupler package includes an integrated capacitor, a ferrite layer, and a coupler coil. The transmitter coil in the sensor package is energized by an external power source which in turn energizes the coupler coil in the coupler package. The sensor then measures the rotational position of the coupler package relative to the sensor package by detecting and measuring, with the two part receiving coil, the signal returned by the coupler coil. The signal processor calculates the position of the coupler package relative to the sensor package by comparing the coupling factors between the coupler package and the sensor package.
