<p>The VIB I/O Module is used for online monitoring of the machine vibration condition. It records the two most important parameters required for condition analysis: vibration severity and roller bearing condition.</p><p>Vibration velocity is a measurement for 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 three quality categories.</p><p>Roller bearing condition is evaluated on the basis of high-frequency shock impulse signals. Shock impulses are momentary impulses arising from mechanical damage to roller bearings or the bearing surfaces.</p><p>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 damage can be detected at an early stage.</p><p>A special Tandem-Piezo^® acceleration sensor serves as encoder to facilitate simultaneous measurement of machine vibrations and high-frequency shock impulse signals.</p>
