Online Condition Monitoring for Single Aggregates

The VIBGUARD compact offers 6 measuring channels for continuous real-time monitoring of fast and highly dynamic motion sequences. Thus VIBGUARD compact fulfills in particular the high maintenance requirements of critical single aggregates, characterized by high availability, high aggregate value, complex drives, and changing operating conditions.

All 6 measuring channels are designed as highly dynamic analog input channels and can be equipped with either standard ICP vibration sensors or with voltage input signals for process variables. They provide in depth diagnostic data such as time signals or envelope signals, and up to 6 characteristic values such as vibration characteristic or bearing condition.

VIBGUARD compact can therefore ensure reliable monitoring – even with frequently changing operating conditions. It can thus protect against unplanned downtimes, secure production, and sustainably increase single aggregate efficiency.

The VIBGUARD compact 'Intelligent Event Recorder' stores relevant results, fully automatically and continuously, thus providing the fundamental basis necessary to comprehensive machine diagnostics. Its bidirectional Modbus TCP interface enables instant VIBGUARD compact Online Condition Monitoring System integration to your Industry 4.0 environment.

Whether pre-installed in an IP 65 compact housing, or as a switch cabinet system module; the VIBGUARD compact is perfect for diagnostic condition monitoring of extruders, large fans, multiphase or vacuum pumps, turbocompressors, mill stands, or centrifuges.
