Description
BENTLY NEVADA 3500/42M 176449-02 Proximitor/Seismic Monitor
1. Product Description
The BENTLY NEVADA 3500/42M 176449-02 is a 4-channel vibration and displacement monitoring module designed for machinery protection systems. As part of the 3500 Series, it integrates with BENTLY’s modular racks to accept inputs from proximity, velocity, or acceleration transducers, providing real-time measurements for radial vibration, thrust position, eccentricity, and more. The 3500/42M supports programmable alarm setpoints and dual-channel functionality, allowing simultaneous monitoring of two parameters (e.g., vibration and temperature) per module. Its epoxy-sealed design ensures durability in harsh industrial environments, while intuitive software configuration simplifies setup and maintenance.

3. Advantages and Features
- Multi-Parameter Monitoring: Simultaneously tracks up to two parameters per channel (e.g., vibration and axial position).
- TMR Configuration: Supports Triple Modular Redundancy for critical applications, with 2-out-of-3 voting logic to prevent false alarms.
- High Precision: 0.1% linearity error ensures accurate measurements in rotating machinery.
- Hot-Swap Capability: Modules can be replaced without powering down the system, minimizing downtime.
- Remote Access: Web-based interface allows real-time monitoring and parameter adjustments.
4. Application Areas and Use Cases
Industry Applications:
Industry Applications:
- Energy: Steam turbines, gas compressors in power plants.
- Manufacturing: CNC machines, pumps in automotive factories.
- Marine: Propulsion systems on offshore vessels.
Case Study: A U.S. refinery reduced maintenance costs by 30% using the 3500/42M to predict bearing failures in pumps, avoiding $2M in unplanned downtime over two years.
5. Competitor Comparison
- Higher Channel Density: 4 channels vs. typical 2–3 channels in comparable modules.
- Enhanced Redundancy: TMR support with dual voting mechanisms, whereas most alternatives offer single-channel redundancy.
- Wider Temperature Range: Operates at -40°C to +85°C, outperforming modules limited to 0°C–70°C.

6. Selection Recommendations
- Channel Needs: Choose the 3500/42M for 4-channel systems; use the 3500/45 for fewer channels.
- Safety Compliance: Ensure alignment with API 670 standards for machinery protection.
- Expandability: Pair with 3500/33 relay modules for automated shutdown capabilities.
7. Precautions
- TMR Installation: In redundant systems, install modules in groups of three adjacent slots.
- Sensor Compatibility: Verify transducer type (proximity vs. seismic) matches module configuration.
- Software Updates: Regularly update the 3500 Rack Configuration Software for firmware improvements.
