Description

BENTLY NEVADA 3500/50M Tachometer Module

 

1. Product Description
The BENTLY NEVADA 3500/50M is a dual-channel tachometer module designed for real-time monitoring of rotating machinery in industrial environments. As part of the 3500 Series Monitoring System, it converts signals from proximity probes or magnetic pickups into precise speed, acceleration, and direction measurements, enabling proactive maintenance and fault detection. With configurable alarm thresholds and dual-channel redundancy, the 3500/50M ensures reliability in critical applications such as turbines, compressors, and generators. Its compact design, wide temperature range, and compatibility with 3500 racks make it ideal for power generation, oil & gas, and manufacturing sectors.

  • Dual-Channel Redundancy: Supports simultaneous input from two sensors for fault-tolerant operation, reducing downtime risks by 40% in critical systems.
  • Precision Measurement: Real-time calculation of speed, acceleration, and direction with ±0.1% accuracy.
  • Flexible Alarming: Programmable alerts for overspeed, acceleration spikes, and reverse rotation via 3500 Rack Configuration Software.
  • EMI Resistance: Shielded design and galvanic isolation ensure stable performance in high-noise environments.
  • Hot-Swap Capability: Enables module replacement without system shutdown, minimizing maintenance downtime.
4. Application Areas and Use Cases
Industry Applications:
  • Oil & Gas: Turbines, compressors, and pumps.
  • Power Generation: Steam turbines and generators.
  • Manufacturing: High-speed rotating equipment.
Case Study: A U.S. power plant reduced generator failures by 30% using the 3500/50M to detect sudden speed fluctuations. Early intervention through alarm notifications saved $800,000 in repair costs.
5. Competitor Comparison
  • Higher Redundancy: Dual-channel design outperforms single-channel alternatives in safety-critical applications.
  • Wider Temperature Range: Operates reliably at -40°C to +85°C, exceeding many competitors’ 0–70°C limits.
  • Integrated Functionality: Combines speed monitoring with acceleration analysis, reducing the need for separate modules.

6. Selection Recommendations
  • Redundancy Needs: Opt for 3500/50M for dual-channel reliability; choose single-channel modules for non-critical machinery.
  • Sensor Type: Use proximity probes for non-contact measurements or magnetic pickups for cost-effective solutions.
  • Expandability: Pair with 3500/22M transient modules for comprehensive vibration and speed analysis.
7. Precautions
  • Sensor Calibration: Verify probe alignment and signal integrity every 6 months to maintain accuracy.
  • Heat Management: Install in well-ventilated areas to prevent overheating in high-temperature environments.
  • Firmware Updates: Apply BENTLY-recommended updates to access new features and security patches.
