The VIB I/O module is used for online monitoring of machine vibration.
The module collects the two most important parameters for machine condition
analysis: Vibration velocity and shock pulse.
Vibration velocity is a measure of the energy of the machine vibration and thus
a good indicator of the vibration force which affects the machine.
ISO 10816-3 gives guidelines for evaluation. The actual value of the measured
vibration velocity is divided into four different quality categories.
Evaluation of the bearing condition is based on high frequency shock pulses.
Shock pulses are short pulses that are induced by mechanical damage to the
rolling element or the contact surface.
The measured shock pulses are divided into three different categories that
describe the bearing condition: “good“, “restricted“, “bad“. Registration and
evaluation of the measurement results in a trend curve which allows detection
of damage at an early stage.
The use of a special Tandem-Piezo sensor allows measurement of machine
vibration and high frequency shock pulses at the same time.
