There are two ISO recommendations concerning machine condition monitoring using this type of measurement; the much-used ISO 2372 and the more recent ISO 10816, which is a replacement of the older standard. ![]() ISO 10816 keeps the lower frequency range flexible between 2 and 10 Hz, depending on the machine type. If two or more of these parameters are measured, vibration severity is the one returning the relative highest RMS value. For certain machines, ISO 10816 also recognizes peak-to-peak values as condition criteria. The time signal is the electrical signal coming from the transducer. It gives a reflection of all events happening in the machine. It shows the time between events and how much energy is generated from the event. It is possible to distinguish between various faults that occur with the same pattern in an FFT spectrum. They can be individually activated and are shown in measuring result tables and as diagrams. Available condition parameters are. Most fault symptoms are automatically configured by using the rpm as a variable. Some require an input, e. 2372 Vibration Standard Software When TheSuitable symptoms and symptom groups are selected from a menu in the Condmaster analysis and diagnostic software when the measuring point is set up. Once measuring results are collected, an EVAM criterion can be created that compares new parameter values with the statistical mean value and displays a dimensionless condition value against a green-yellow-red scale. We calculate the time delay between the passage of the tachometer pulse and the peak of the frequency component of interest from the vibration transducer at the speed of rotation. The value presented is a relative angle, not an absolute, because there is no compensation for phase lag in the transducer or the electronic circuits. Instant evaluation of bearing condition is given in an easily understood green-yellow-red color scheme.
