Description
BENTLY NEVADA 3500/42M Proximitor/Seismic Monitor Module
The
BENTLY NEVADA 3500/42M is a 4-channel proximity and seismic monitor module designed for the 3500 Machinery Monitoring System. It interfaces with proximity and seismic transducers to measure vibration, position, and acceleration in rotating machinery. The module processes raw signals, applies alarm thresholds, and communicates data to control systems via analog or digital outputs. With configurable channels and support for multiple sensor types, the
3500/42M ensures reliable condition monitoring in power generation, oil and gas, and heavy industrial environments.

- Multi-Functionality: Supports proximity (position) and seismic (vibration/acceleration) measurements in a single module.
- Real-Time Alarm Triggers: Compares measured values against user-programmable setpoints for immediate alerts.
- Flexible Configuration: Channels can be paired for radial vibration or individual for thrust position monitoring.
- Noise Immunity: Shielded inputs and advanced filtering reduce interference in harsh environments.
- Ease of Integration: Works seamlessly with BENTLY’s 3500 Rack Configuration Software for setup and diagnostics.
Case Study: A U.S. refinery reduced compressor downtime by 18% using the 3500/42M to detect early bearing wear through vibration analysis.
Industries:
- Power plants, petrochemical facilities, steel mills, and marine systems.
- Turbines, pumps, motors, and gearboxes.
Case Study: A European power plant improved generator reliability by 22% using the module to monitor shaft displacement and adjust maintenance schedules.
The BENTLY NEVADA 3500/42M outperforms comparable modules with:
- Higher Channel Density: 4 channels vs. 2–3 in most alternatives.
- Extended Temperature Range: Operates in extreme conditions (-30°C to +65°C).
- Dual Sensor Support: Simultaneously handles proximity and seismic inputs without additional hardware.

- System Compatibility: Ensure compatibility with existing 3500 racks and software.
- Environment: Choose this module for high-vibration or high-temperature settings.
- Cost Efficiency: Balances advanced features with lower maintenance costs compared to dedicated vibration systems.
- Shielding: Use shielded cables grounded at the module end to minimize noise.
- Power Stability: Ensure a clean DC 24V power supply to avoid signal fluctuations.
- Calibration: Regularly verify sensor calibration via the 3500 Rack Configuration Software.
