Product Description
The Bently 3500/50M is a dual-channel tachometer module designed for real-time monitoring of shaft speed, acceleration, and direction in rotating machinery. As part of the Bently 3500 modular monitoring system, it accepts inputs from proximity probes or magnetic pickups to ensure precise measurements. The module supports configurable alarm setpoints, zero-speed detection, and reverse-rotation notifications, making it ideal for critical applications in power generation, oil & gas, and manufacturing. Its integration with the Bently 3500 Rack Configuration Software enables easy customization, while compatibility with System 1 software allows for advanced analytics and predictive maintenance.
Technical Parameters
| Parameter | Specification |
|---|---|
| Input Voltage | 24 VDC ±10% (module operation) |
| Power Supply | 85–264 VAC or 20–30 VDC (external input) |
| Channels | Dual-channel (A and B) for redundancy |
| Speed Range | 0–100,000 RPM (configurable) |
| Input Signals | Proximity probe (±24 VDC) or magnetic pickup |
| Alarm Outputs | 4 solid-state relays (2 per channel) |
| Communication | Modbus RTU (RS-485) for integration with PLC/DCS |
| Operating Temperature | -40°C to +70°C |
| Compatibility | Bently 3500 racks, System 1 software |
Advantages and Features
- Dual-Channel Redundancy: Ensures continuous operation by comparing two independent speed signals.
- Flexible Configuration: Supports multiple monitoring modes (e.g., speed band alarming, zero-speed detection).
- Keyphasor Integration: Eliminates the need for a separate keyphasor module by providing conditioned signals to the 3500 rack.
- Peak Hold Function: Stores maximum speed and reverse-rotation events for post-incident analysis.
- Hot-Swap Capability: Allows module replacement without system shutdown.
Application Fields and Case Studies
- Energy: Monitoring gas turbine speed in power plants.
- Oil & Gas: Protecting compressors in offshore platforms.
- Manufacturing: Controlling conveyor systems in automotive assembly lines.
Case Study: A petrochemical plant reduced downtime by 20% using the 3500/50M to detect and alarm early signs of rotor imbalance in a centrifugal compressor.
Competitor Comparison
The 3500/50M differentiates itself with:
- Built-in redundancy for SIL 2 compliance, reducing reliance on external safety systems.
- Faster response time (≤10 ms) compared to legacy tachometers.
- Seamless integration with Bently’s comprehensive System 1 analytics suite.
Selection Recommendations
- System Integration: Pair with Bently 3500/22M frame interface module for centralized data management.
- Safety Requirements: Opt for dual-channel configuration in applications requiring high reliability.
- Expansion Needs: Reserve rack slots for future modules like vibration or displacement monitors.
Precautions
- Sensor Calibration: Ensure proper alignment of proximity probes or magnetic pickups.
- Power Stability: Use filtered power supply to prevent voltage fluctuations.
- Firmware Updates: Regularly update to access new features and enhance security.
