Product Description

The Bently Nevada 3500/45 Position Monitor is a key component of the Bently Nevada 3500 series machinery protection system. It’s designed to monitor and protect machinery by continuously measuring the axial position (thrust), differential expansion, or case expansion of rotating equipment.

Product Parameters

The 3500/45 module is a full-height, four-channel card that accepts input from proximity transducers or LVDTs (Linear Variable Differential Transformers). The module provides four configurable channels for various position measurements. Here are some of its key parameters:

• Input Channels: 4 channels per module, configurable for different position measurements.
• Transducer Inputs: Compatible with Bently Nevada proximity probes (5mm, 8mm, 11mm, 25mm), as well as LVDT sensors.
• Measurement Range: Depends on the specific transducer used. Proximity probes typically offer ranges from 1mm to 2mm, while LVDTs can have much larger ranges.
• Data Processing: The module provides a buffered output of the position signal for each channel, allowing for further analysis.
• Alarms: Two alarm setpoints (Alert and Danger) per channel, which can be configured for various trip behaviors (e.g., latching, non-latching).
• Power Consumption: The module is powered by the 3500 rack’s backplane.
• Operating Temperature: Typically -30°C to +65°C (-22°F to +150°F).

Product Advantages

The Bently Nevada 3500/45 offers several significant advantages for machinery protection:

• Enhanced Machine Protection: It provides real-time, continuous monitoring of critical position parameters, helping to prevent catastrophic failure by detecting excessive thrust or differential expansion before it causes damage.
• High Reliability: As part of the 3500 series, it’s built to meet stringent industry standards for reliability and durability in harsh industrial environments.
• Flexibility: The module’s four-channel design and configurable inputs allow it to be adapted for a wide range of applications and machinery types.
• Integration: It seamlessly integrates into the Bently Nevada 3500 rack, sharing power and communication with other modules, which simplifies installation and maintenance.
• Advanced Diagnostics: It offers a buffered output for each channel, which is crucial for detailed vibration analysis and troubleshooting, enabling predictive maintenance strategies.

Precautions

To ensure proper and safe operation of the 3500/45 module, consider the following precautions:

• Professional Installation: The module should be installed by trained personnel familiar with the Bently Nevada 3500 system.
• Correct Transducer Selection: Ensure the correct type and size of proximity probe or LVDT is used for the specific application and measurement range.
• Proper Grounding: The 3500 rack and all associated components must be properly grounded to prevent electrical interference and ensure accurate readings.
• Environmental Conditions: The module should be operated within its specified temperature and humidity ranges to prevent damage and ensure reliable performance.
• Regular Calibration: Transducers and the 3500/45 module should be periodically calibrated to maintain accuracy.

Applications

The Bently Nevada 3500/45 is widely used in industries that rely on large, critical rotating machinery. Its primary applications include:

• Thrust Bearing Protection: Monitoring the axial position of turbine and compressor shafts to protect against thrust bearing failure.
• Differential Expansion: Measuring the relative expansion between a turbine casing and its rotor, which is critical for steam turbines during startup and shutdown.
• Case Expansion: Monitoring the expansion of a machine’s casing to ensure it remains within safe operating limits.
• Axial Position of Motors and Generators: Protecting the rotor from coming into contact with the stator or other components.

This module is a cornerstone of a robust machinery protection system, playing a critical role in preventing downtime and ensuring the long-term health of valuable assets.
