    摘要: A method for determining the temperature of an away-facing surface of an object, wherein at least one ultrasonic pulse is transmitted through a surface of the object facing a transmitter/receiver unit into said object; the at least one ultrasonic pulse is reflected at least partially in the direction of the transmitter/receiver unit on the surface of the object facing away from the transmitter/receiver unit; and the reflected part of the at least one transmitted ultrasonic pulse is received by the transmitter/receiver unit. At least one temperature value for the object surface facing the transmitter/receiver unit is also determined; at least one value is determined for the propagation time of the at least one ultrasonic pulse through the object, and at least one temperature value for the object surface facing away from the transmitter/receiver unit is determined by the at least one temperature value for the object surface facing the transmitter/receiver unit and the at least one propagation time value.

    摘要: A magnetoelastic torque sensor (1) has an emission coil (7) for generating a magnetic field in an object (3), the torque of which is to be determined. The emission coil is axially oriented (A) and has an axial emission coil end surface (15) which can be guided towards the object (3). At least two reception coils (9, 33, 43) at a distance from the emission coil and having, respectively, a receiving coil end surface (17) which can be guided towards the object (3) to capture a response signal induced in the object (3) by the magnetic field of the emission coil (7, 31, 41). At least the receiver coil end surface (17) of one of the receiver coils protrudes beyond the emission coil end surface (15) to a selected distance from the object (3).

    摘要: Systems and methods to monitor a signal from an apparatus are disclosed. A feature extracted from the signal is automatically defined. Signals are received over a period of time wherein the apparatus is in a normal operational mode. Features are classified in a learning mode and are applied to create a reference model that defines a within-normal operational mode. In a testing mode a signal generated by the apparatus is received, a feature is extracted and classified. Instantaneous data generated in operational mode by the apparatus is classified by the system as abnormal if it does not lie within boundaries of the reference model or contains information/structure in an orthogonal subspace. A learned reference model is augmented by a user or automatically. In one illustrative example the apparatus is a power generation equipment and the signal is an acoustic signal.
