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： The invention relates to the detection of angular accelerations on wheelsets (2, 3) of a rail vehicle, wherein - measurement values of the rotational movement of the wheelset (2, 3) and/or of the rotational movement of a drive train (6, 7), which is coupled to the wheelset (2, 3), are measured by a rotational movement sensor (1), - from the measurement values, it is determined that an angular acceleration is present, and/or the measurement values are used as an input variable for control of a drive motor (6) of the rail vehicle in order to reduce and/or avoid an angular acceleration, and - the rotational movement sensor (1) obtains the measurement values as a result of electric flows being induced by a magnetic field in a part (32) of the sensor (1) which rotates in conjunction with the wheelset (2, 3) or with the drive train (6, 7), as a result of the induced electric flows generating an additional magnetic field and, on the basis of the additional magnetic field, inducing an electric current in a non-rotating part (33) of the sensor (1), from which electric current the rotational movement measurement values are determined.

摘要： The invention proposes a method for monitoring a rotation of a compressor wheel (12), in particular a compressor wheel (12) of an exhaust gas turbocharger, and an apparatus (10) for carrying out the method. The method according to the invention provides for the compressor wheel (12) to have a number n of blades (14) on the circumference, wherein a sensor (16) is provided for the purpose of detecting at least one rotation property of the compressor wheel (12), especially the speed or rotational speed, wherein the sensor (16) is an inductive sensor (16), wherein the sensor (16) generates at least one output signal (20) on the basis of the eddy currents generated by being guided past the blades (14), wherein the rotation property, in particular the rotational speed, of the compressor wheel (12) is inferred from a fundamental frequency of the output signal (20), and wherein an item of information relating to a fault of the compressor wheel (12) can also be gathered from at least one modulation of the output signal (20), in particular amplitude modulation. An imbalance of the compressor wheel can be detected, in particular.

摘要： Es wird eine Sensorvorrichtung (110) zur Erfassung mindestens einer Rotationseigenschaft vorgeschlagen, insbesondere zur Drehzahlerfassung eines Verdichters (111) zum Verdichten fluider Medien. Die Sensorvorrichtung (110) weist mindestens ein erstes Element (132) und mindestens ein zweites Element (134) auf. Das erste Element (132) und das zweite Element (134) sind um eine Rotationsachse (136) relativ zueinander rotierbar. Das erste Element (132) und das zweite Element (134) sind gegeneinander entlang der Rotationsachse (136) versetzt angeordnet. Die Sensorvorrichtung (110) weist mindestens einen mit dem ersten Element (132) verbundenen Felderzeuger (120) auf, welcher eingerichtet ist, um an mindestens einem Ort des zweiten Elements (134) mindestens einen Wirbelstrom zu erzeugen. Das erste Element (132) umfasst weiterhin mindestens einen Feldsensor (122) zur Erfassung mindestens eines durch den Wirbelstrom erzeugten Feldes. Das zweite Element (134) ist eingerichtet, um das durch den Wirbelstrom erzeugte Feld in Abhängigkeit von einer Winkelstellung des zweiten Elements (134) relativ zum ersten Element (132) zu variieren.
