4.1.1.2 Description
The VIB-I/O module is used in the online-monitoring of the machine vibration
condition. It records the two most important parameters required for the
condition analysis: vibration severity and roller bearing condition.
The severity of vibration is a measurement for the machine vibration energy
and therefore, a suitable indicator for the vibration forces acting on the
machine. The ISO 10816-3 standard is used to assess the results in which the
effective values of the (measured) vibration are divided into four quality
categories.
The roller bearing condition is evaluated on the basis of high-frequency shock
impulse signals. Shock impulses are momentary impulses arising from
mechanical damages to roller bearings or the bearing surfaces.
The evaluation uses a scale where the measured shock impulses are divided
into three bearing condition categories: 'good', 'limited' and 'poor'. By
recording the measurement results and evaluation in a trend curve, bearing
damages can be detected at an early time.
