The new P4700 range of hardware has been designed for the monitoring and analysis of vibration and associated parameters within an industrial environment. The P4700 hardware seamlessly integrates within Prosig's existing PROTOR products for rotating machine vibration monitoring and plant protection.

The P4700 consists of a series of individual components which fit together as required into a rack-mount chassis. The P4700 is designed to be mounted close to the signal source thus reducing expensive cabling costs. Communication to the P4700 is via standard TCP/IP Ethernet. For particularly harsh environments the P4700 may be mounted in an appropriately IP-rated enclosure for protection from excessive dirt and moisture. P4700 uses 24V DC power.

The P4700 uses the latest microprocessor technology to provided a powerful but flexible monitoring and signal processing system in order to provide condition monitoring for a wide variety of items of plant. The P4700 is extensively used for the analysis of rotating machines where vibration is analyzed relative to a once-per-revolution keyphasor signal to yield harmonic amplitude and phase components. However, the P4700 may also be used for non-rotating plant to provide either simple, continuous overall level monitoring or by providing "spectral banding" analysis.

The P4700 family of components allows systems to be configured easily for a wide variety of applications. A single P4700 chassis consists of a processor segment and a signal segment. The signal segment may be either a 32-channel dynamic segment with individual, parallel ADCs per channel, ideal for monitoring high-speed vibration data for one or more item of plant. Alternatively a static segment may be selected which provides a 48-channel multiplexed arrangement for low-cost, slower speed monitoring for less critical plant items or for plant analogue (static) signals.

The processor segment provides the communication and control interface and also the digital signal processing engine. For full flexibility inter-communication between the processor and the signal components is via USB. The in-built processor runs a fully functional operating system allowing easy remote maintenance and upgrade. The system runs from embedded solid-state disk (DiskOnChip) for high reliability in an industrial environment. A hard disk may be fitted for long-term data storage and security in the event of long-term ethernet loss. A complete monitoring system may consist of several P4700 systems inter-connected. Each system may be monitoring separate items of plant or for a highly instrumented machine several P4700 systems may be integrated together to monitor the complete machine.

The P4700 provides fully programmable signal conditioning which supports all common vibration transducers such as shaft displacement probes , ICP and 4-20 mA devices. The conditioning provides high common mode protection. Full galvanic isolation can be provided as an additional external device.
