Remote monitoring vibration monitoring system with versatile analysis capability

The commtest vbOnline multi-channel vibration monitoring remote supervision system has been developed for monitoring and protecting a wide variety of rotating machinery, such as fans, pumps, compressors, mills, crushers, mixers, etc. The condition of the monitored machines can be viewed and on-site vibration data (Ethernet) can be analyzed through the commtest vbOnline system - and wireless communication can also be implemented.

The commtest vbOnline unit can receive signals from sixteen or even thirty-two ICP-type (with built-in charge amplifier) piezoelectric vibration acceleration and velocity sensors, as well as eddy current displacement sensors, AC/DC voltages, and 4...20 mA transmitters. In addition, four tachometer signals can be connected to the unit. To accommodate a larger number of channels, multiple commtest vbOnline units can be networked.

• Reception of 16 or 32 sensors (powered by the instrument)
• Connectable sensors: vibration acceleration and velocity sensors, eddy current displacement transducers, AC/DC process signals, 4...20 mA transmitters
• Reception of 4 tachometers (speed sensors)
• Simultaneous data recording per channel pair
• Automatic alarm and information transmission (e.g., via email)
• Built-in indicator LEDs and relays (status, alarms)
• Can be used as a standalone unit or as a network device
• Ethernet or wireless communication
• Compact design, mountable on DIN rail

• 4 relay outputs (system status and alarms) programmable with selectable operation
• Communication: Ethernet, TCP/IP, and RS232

The commtest vbOnline processes the signals from the sensors according to the set measurement range and signal integration, operates the built-in relays and indicator LEDs, and provides information (status indicators, spectra, timestamps, log data) to the monitoring, archiving, and diagnostic software running on the PC.

The commtest vbOnline unit comes with the Ascent Level-3 PC software, which can continuously query and display the data recorded by the on-site unit and the status of each channel. The software allows remote control and configuration of the commtest vbOnline device, enabling settings such as channel-specific alarm levels, operation of relay outputs, and configuration of data recording and logging times via the PC.

Data recording can be time- and event-triggered. The condition of the monitored machine can be continuously monitored, warnings and alarm signals can be listed and acknowledged remotely. If required, alarms and status notifications can be automatically forwarded via email.

Both current and stored (archived) data can be viewed in the PC software. In addition to log data and trend plots, there is also the possibility to display and perform high-level analysis of timestamps and spectra.
