Method of monitoring equipment and system for carrying out the method |
摘要 |
Method of monitoring equipment wherein a measured value signal in the form of an electrical a-c signal is fed to the measuring channel of an electric circuit and a mean value output signal is formed by the electronic circuit in accordance with the amplitude of the measured value signal, which includes setting an amplitude limit as a function of the mean value signal and the amplitudes of the measured value signal, automatically adapting the amplitude limit with a predetermined time constant to changes in the mean value signal, setting a limit of a number of occurrences when the amplitudes of the measured value signal exceed the amplitude limit, and activating an alarm if the occurrence limit is surpassed within a settable time period, and system for carrying out the method.
