  • Patent number: 10508974
    Abstract: A “store on alert” vibration data acquisition mechanism uses scalar data produced by a vibration monitoring device as a predicate to capturing and storing analytical vibration data in the vibration monitoring device. The scalar data may consist of scalar process variables generated in the vibration monitoring device that are acquired at a fixed interval, such as PeakVue and Overall Vibration. At each interval, these scalar data values are compared to machine performance threshold levels, such as ADVISE, MAINT and FAIL, to determine whether analytical vibration data is to be stored separately inside the vibration monitoring device. Since the analytical vibration data is captured based on a predicate inside the vibration monitoring device (i.e., comparison of the scalar value to the thresholds), the analytical vibration data includes more relevant diagnostic information about a specific machine performance event.

  • Patent number: 10502677
    Abstract: For a monitored corrosion sensor, such as a sensor based on one or more mechanical oscillators disposed in a fluid flow, one or more values are measured over time. The values can be measured at a desired frequency, such as a once per second, once per minute, or another convenient frequency. The measured data can then be analyzed as a time series. The goal of the analysis is to identify variations in the time series data that are sufficiently unexpected relative to the prior behavior of the time series within a given time window. The identified variations can then, for example, be excluded from consideration when determining a corrosion-related value for the sensor.

  • Patent number: 10436672
    Abstract: A system for the purpose of condition monitoring of gearboxes includes processing equipment that is configured to receive data that contains information of a spectrum of mechanical vibrations measured from a gearbox being monitored. The processing equipment is configured to search, from the spectrum of mechanical vibrations, at least two spikes on such frequencies which correspond to a phenomenon such as for example a bearing fault. The phenomenon is defined with at least two phenomenon-specific frequencies and with reference values of amplitudes relating to these phenomenon-specific frequencies. The processing equipment is configured to form an indicator of probability of occurrence for the phenomenon on the basis of amplitudes of the searched spikes and the reference values of the amplitudes. The fact that the indicator is formed on the basis of amplitudes of two or more spikes which relate to this phenomenon improves the reliability of the indicator.
