Bently Nevada 3500/50-01-00-01 Tachometer Module Overview

The Bently Nevada 3500/50-01-00-01 Tachometer Module (part numbers 133388-02, 133442-01) is a precision dual-channel monitoring instrument engineered for continuous shaft rotational speed measurement, acceleration tracking, and directional analysis in critical rotating equipment. This module integrates seamlessly into the 3500 Series monitoring framework, delivering real-time performance data essential for predictive maintenance and machinery protection.

Technical Specifications

  • Channels: 2 independent tachometer inputs
  • Input Type: Proximity probe, magnetic pickup, or optical sensor compatible
  • Speed Range: 0 to 100,000 RPM (configurable)
  • Accuracy: ±0.01% of reading
  • Update Rate: Configurable from 1 to 60 seconds
  • Operating Temperature: -30°C to +65°C (-22°F to +149°F)
  • Power Consumption: 5.5W typical
  • Compliance: API 670, ISO 20816, CE marked

Application Scenarios

This tachometer module excels in demanding industrial environments where precise rotational monitoring is mission-critical:

  • Turbomachinery: Steam turbines, gas turbines, and compressor trains requiring phase reference and speed validation
  • Power Generation: Generator sets, hydroelectric units, and auxiliary drive systems
  • Oil & Gas: Pumping stations, pipeline compressors, and offshore platform equipment
  • Manufacturing: High-speed spindles, paper machines, and continuous process equipment

Integrated Solutions

The 3500/50 module functions as a cornerstone component within comprehensive vibration monitoring architectures. When paired with proximitor monitors and seismic sensors, it enables advanced diagnostics including:

  • Phase-locked vibration analysis for unbalance detection
  • Startup/shutdown transient monitoring with speed correlation
  • Torsional vibration assessment through multi-point speed comparison
  • Automated alarm generation based on speed deviation thresholds

Common Questions

Q: Can this module accept multiple sensor types simultaneously?
A: Yes, each channel independently supports proximity probes, magnetic pickups, or optical sensors with field-configurable input conditioning.

Q: Is hot-swapping supported during operation?
A: The module supports online insertion and removal when installed in a properly configured 3500 rack with redundant power.

Q: What communication protocols are available?
A: Standard Modbus protocol via the 3500 rack interface, with optional Ethernet connectivity through communication gateway modules.

Q: Does it require calibration after installation?
A: No field calibration needed ach unit ships factory-calibrated with traceable certification. Periodic verification recommended per site maintenance schedules.
