The Bently Nevada 3500/20 125744-02 is a vibration monitoring system card from the Bently Nevada 3500 Series, designed for industrial applications to monitor the health and performance of rotating machinery like motors, pumps, compressors, and turbines.

Product Name:

Bently Nevada 3500/20 125744-02
This is an Accelerometer/Velocity Transducer Input Module used in Bently Nevada’s 3500 series machinery protection and condition monitoring systems.

Product Description:

The Bently Nevada 3500/20 module is part of the Bently Nevada 3500 Series, which is a highly reliable and flexible machinery protection system. The 3500/20 card is used for processing the signals from vibration sensors (accelerometers or velocity transducers) in industrial rotating equipment. It performs continuous monitoring of vibration signals from critical equipment and provides real-time diagnostics for predictive maintenance.

This card is installed into the Bently Nevada 3500 Rack, which can be configured to handle multiple input and output modules for comprehensive machinery monitoring. The module processes the signals from vibration sensors, allowing users to track machine health, detect abnormalities, and avoid unplanned downtime.

Product Parameters:

• Input Channels: Typically supports two channels of input per card for vibration sensors (accelerometers or velocity transducers).
• Signal Types:
  • Accelerometer (seismic sensors)
  • Velocity Transducer
• Input Voltage: 12V or 24V DC (depending on the configuration)
• Input Sensitivity Range:
  • Accelerometer: 100 mV/g to 10 V/g
  • Velocity Transducer: 10 mV/in/s to 2 V/in/s
• Frequency Response: Wide frequency range, often up to 10 kHz or higher.
• Signal Processing: Real-time processing for continuous vibration measurements, including waveform analysis and spectral analysis.
• Built-in Diagnostics: Includes self-diagnostics for early detection of sensor or system issues.
• Connector Type: Typically utilizes a standard 25-pin or similar connector for sensor interface.
• Size: 3U high, fits into a standard 3500 series rack system.

Specifications:

• Environmental Operating Range:
  • Temperature: 0°C to 60°C (32°F to 140°F)
  • Humidity: 5% to 95% non-condensing
• Power Consumption: Approximately 4-6 watts per card.
• Electrical Isolation: Ensures safe operation with protection against ground loops and electrical interference.
• Signal Output: Output signals can be used to trigger alarms or warnings based on predefined thresholds.
• Signal Output Options: Alarm relays, analog outputs, digital outputs, or network communication (depending on system configuration).
• Compliance: Typically compliant with UL, CE, and other industrial safety standards.

Product Use:

The Bently Nevada 3500/20 125744-02 module is widely used in industries such as:

• Oil and Gas
• Power Generation
• Mining
• Pulp and Paper
• Chemical Processing
• Water Treatment

Applications include monitoring critical rotating machinery like:

• Pumps
• Compressors
• Turbines
• Motors
• Fans
• Generators

The module helps in early detection of machine faults (like unbalance, misalignment, bearing wear, etc.) and provides key insights to help improve maintenance strategies, prevent catastrophic failures, and extend the lifespan of critical machinery.

Key Benefits:

• Real-Time Monitoring: Continuous monitoring of machine condition, with the ability to detect faults in real-time.
• Predictive Maintenance: Identifies developing faults early, allowing for predictive maintenance strategies.
• Data Logging and Analysis: Gathers and stores vibration data for analysis, enabling deeper insights into machinery performance.
• Reduce Downtime: By detecting potential issues before they cause system failures, it helps in reducing unscheduled downtime.
• Flexible Integration: Can be integrated into larger machinery protection systems using Bently Nevada’s 3500 monitoring platform.

This module is essential for industries that require high levels of machinery reliability and operational efficiency.
