PROTOR

PROTOR is a complete hardware and software solution for online vibration monitoring of rotating machinery. Acquisition units monitor your machines and are networked to a central server, giving engineers access to real-time and historical data either on-site or remotely via LAN, WAN or VPN. Data and reports are presented in both graphical and numerical formats.

Available as a rack-mounted unit for permanent installation or as a portable system, PROTOR is rugged and built to withstand the demanding conditions typically found in power stations. A range of configurations gives you full flexibility over the number of channels and machines you monitor.

Key benefits

Improved efficiency

Reliable diagnostics reduce downtime and improve overall plant efficiency.

Lower capital costs

Extending machine service life reduces the need for costly replacement.

Better machine health data

Supports predictive maintenance, helping to avoid or limit machine damage.

Improved safety

Early warning of developing faults reduces the risk of unexpected failure, damage and injury.

Data where you need it

Data is delivered to your desktop, whether you are on site or working remotely.

Reduced servicing

Repair or replace only the parts that are genuinely damaged or worn.

Lower repair costs

Recognise problems before they cause serious damage.

Reduced downtime

Machines can be monitored and maintained while they remain in service.

Fewer shutdowns

Scheduled maintenance can be planned around production requirements.

Flexible system configuration

The standard PROTOR unit provides stand-alone monitoring and storage for up to 32 channels and 4 tachometer or phase reference signals. Where fewer channels are needed, the system can be configured with 8, 16 or 24 channels, supporting 1, 2 or 3 tachometer signals respectively.

PROTOR can monitor a single machine, with all 32 channels captured relative to one phase reference, or multiple machines, with a tachometer signal associated with each block of 8 channels. Multiple chassis can be combined for larger installations.

Data acquisition and storage

PROTOR provides high-quality, high-speed data acquisition and analysis. Data is acquired synchronously with a once-per-revolution tachometer signal for highly accurate harmonic and sub-harmonic measurements, or on a time basis for slow-speed conditions or where no tachometer signal is available.

A standard signal conditioning module accepts inputs from accelerometers, velocity probes and displacement probes, and the system also supports IEPE/ICP® transducers. Gain, AC/DC coupling and anti-aliasing filter selection are all programmable.

Signal inputs are true differential with high common-mode rejection, making them well suited to transducer signals in industrial environments. PROTOR can run alongside an existing protection or supervisory system, and where raw signals are shared, high-impedance galvanic isolation is available as an option.

The system automatically detects plant operating conditions, including on-load, overspeed, run-up, run-down, barring and slow roll, and adapts its acquisition technique to suit.

User interface and connectivity

PROTOR can be accessed directly via standard monitor, keyboard and mouse ports, or over Ethernet. Typically, engineers connect using a Windows laptop via Ethernet or through an existing station network, which can also provide remote access where WAN or VPN facilities are available. Once configured, PROTOR can be left unattended to collect and store data to its internal disk.

The intuitive graphical user interface makes it easy to select display types and channels using simple point-and-click menus. Screenshots can be copied straight into standard Windows applications, and data can be easily exported.
