摘要： The invention relates to a method for determining the size of a radial gap between rotating and torsion-proof parts, particularly the parts of a turbomachine. According to said method, an original signal emitted by a transmitter device located on the surface of the rotating part is received in a modified manner by a receiver device disposed on the torsion-proof part and is redirected to an evaluation unit. Said evaluation device determines and displays the size of the radial gap from the received signal by determining the parameters of the trajectory of the rotating transmitter device.

摘要： A method for generating a pulse signal sequence using a processor unit is provided that allows calibrating a tip timing measurement system in a turbomachine in order to increase operational security and lifespan of the turbomachine. This is achieved by the method having the steps of: storing a number of wait time elements in a memory unit, creating a pulse signal in a signal output unit during at least one processor cycle, reading a wait time element from the memory unit, and creating a null signal in the signal output unit for a number of processor cycles derived from the wait time element read.

摘要： A method for analyzing the operation of a gas turbine is provided. A neural network based upon a normal operation of the gas turbine is learned. A dynamic pressure signal is read by a pressure sensor in or on the compressor of the turbine, and an operating parameter is read by a further sensor. The dynamic pressure signal is subjected to a frequency analysis, a parameter of a frequency spectrum of the pressure signal being determined. Based upon the measured operating parameter and the parameter of the frequency spectrum of the pressure signal, the neural network is learned. The measured operating parameter and the parameter of the frequency spectrum are input parameters, and a diagnostic characteristic value representing a probability of a presence of operation of the gas turbine as a function of the input parameters is output.

摘要： A method for measurement of the distance between a component which is moved past a reference surface and that reference surface is intended to be suitable in particular for use for the measurement of radial gaps in a turbine, while having particularly high measurement accuracy. To this end, a method based on a triangulation measurement be combined with a reference measurement for determination of the actual speed of the component. In this case, two light beams aligned essentially parallel to one another as well as at least one further light beam, aligned at an angle to the parallel light beams in the movement direction of the component, are monitored for a respectively associated reflection signal which is caused by the component. The time difference between the arrival of the reflection signals associated with the parallel light beams on the one hand, and the time difference between the arrival of the reflection signals associated with one of the parallel light beams and the angled light beam on the other hand, are used to determine a characteristic value for the distance.

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).
