Description

The Bently Nevada 168679-01-01-01-02-03-05-01-01-00-02-02 is a multi-channel ADRE 408 DSPi Dynamic Signal Processing Instrument designed for real-time parallel signal processing, machinery condition monitoring, and advanced vibration data acquisition. The system functions as a digital recorder, spectrum analyzer, signal conditioner, oscilloscope, and filter platform, consolidating complex vibration analysis instrumentation into a single portable or rack-mountable enclosure. This specific build provides a 24-channel dynamic sampling architecture alongside speed, trigger, power supply, and digital replay capabilities for critical turbomachinery and rotating equipment diagnostic testing.

Engineered around a flexible client-server architecture, the 408 DSPi operates either as a standalone data recorder connected to corporate LAN/WAN networks or directly paired with a local host running ADRE Sxp software. The internal 480GB solid-state drive allows continuous high-speed data streaming and event logging independent of an active computer connection. This configuration populated across Slots 1 through 5 supports synchronous and asynchronous sampling across dynamic transducers, phase-reference Keyphasor inputs, and process transmitters without interrupting active data acquisition runs.

Features

• Multi-Channel Dynamic Processing: Populated with three 8-channel dynamic sampling cards, delivering up to 24 simultaneous dynamic input channels with 24-bit A/D conversion.
• Dedicated Speed & Trigger Management: Features one 3-channel speed input card supporting proximity, optical, magnetic, and laser tachometer inputs with built-in signal conditioning and buffered outputs.
• Integrated Transducer Power: Includes a dedicated Transducer Power Supply Card capable of driving positive and negative bias 2-wire constant current sensors or 3-wire proximity probes.
• Hardware Digital Replay Engine: Slot 5 equipped with a Digital Replay Card (without analog outputs) for offline reprocessing and signal re-conditioning without affecting original sampled dynamic data.
• Standalone Storage & Networking: Contains an internal 480GB Solid State Drive (SSD) and dual 1000/100Mb Ethernet ports supporting DHCP or fixed IP addressing for network or local operation.
• Rugged Enclosure & Power Kit: Built in an aluminum chassis with protective powder coating, complete with an external universal AC power supply (90–264 Vac) and hard shipping case for field deployment.
• CE Compliance: Certified to European standards with CE approval marking.

Applications

• Field vibration diagnostics and transient data collection during turbomachinery start-up and coast-down operations.
• Multi-plane balancing analysis using Bently BALANCE software integration.
• Structural dynamics testing and impact hammer excitation measurement.
• Test stand validation and factory acceptance testing (FAT) for industrial turbines, compressors, pumps, and gearboxes.
• Remote machinery condition monitoring across LAN/WAN infrastructure.

Installation Guidelines

1. Inspect the 408 DSPi instrument, external power supply, input cables, and hard shipping case for shipping damage before setup.
2. Ensure proper physical placement on a benchtop or within a standard 19-inch rack, ensuring fan inlets remain unobstructed for cooling air flow.
3. Connect the external power supply using the bayonet-locking DC connector and join the AC line to a 90–264 Vac power outlet.
4. Connect dynamic signal inputs (proximity probes, accelerometers, or velocity sensors) to the SMA front panel connectors using appropriate adapter cables (SMA to BNC).
5. Wire speed sensors or Keyphasor proximity drivers to the 3-channel Speed Input card.
6. If powering sensors directly from the instrument, configure the Transducer Power Supply card switches for the required constant current (positive/negative bias) or -24 V DC settings prior to enabling transducer power.
7. Connect an Ethernet cable from the primary RJ45 port on the instrument to a host PC or dedicated local network switch.

Configuration Guidelines

1. Launch ADRE Quick Configuration or ADRE Sxp software on the client machine.
2. Establish network communication using DHCP auto-discovery or by entering the fixed IP address assigned to the instrument port.
3. Define the machine train layout, shaft rotational orientation, and sensor mounting angles in the software environment.
4. Set channel-specific transducer parameters including scale factor (mV/mil, mV/g), coupling type (AC/DC), and full-scale range.
5. Set up Keyphasor trigger thresholds, edge detection (rising/falling), and multiplier/divider ratios for order tracking.
6. Download the generated configuration file to the 408 DSPi internal SSD storage.

Commissioning & Replacement Recommendations

1. Verify sensor gap voltages and channel DC bias readings on the front display or software screen prior to machine start-up.
2. Initiate a manual sample run from the front panel or client interface to confirm active dynamic sampling across all connected channels.
3. Before replacing or re-configuring cards, stop active recording runs and back up stored database files from the 480GB internal SSD to an external drive or network host.
4. When swapping processing cards, ensure power is removed from the unit before removing card retaining screws.
