The BENTLY NEVADA 135473-01 (3500/25 Keyphasor I/O Module with Internal Barriers and Terminations) serves critical functions in industrial machinery monitoring systems, particularly for rotational equipment.
Its key roles include:
1. Keyphasor Signal Processing
Provides dual-channel Keyphasor signal conditioning for precise phase reference measurement, essential for vibration analysis and speed monitoring.
Converts raw signals from proximity probes or magnetic pickups into digital Keyphasor pulses synchronized with shaft rotation.
2. Safety & Signal Isolation
Features internal barriers and terminations to isolate and protect sensitive monitoring systems from electrical noise or ground loops.
Ensures compliance with hazardous area standards (e.g., ATEX/IECEx) when used in explosive environments.
3. System Integration
Interfaces seamlessly with Bently Nevada 3500 series monitors (e.g., vibration/torsional modules) to enable phase-synchronized diagnostics.
Supports redundant configurations (up to 8 Keyphasor signals) for high-availability systems.
4. Industrial Applications
Turbines/compressors: Tracks shaft speed and phase for imbalance/misalignment detection.
Power plants: Synchronizes vibration data acquisition during startup/shutdown.
5. Key Features
LED status indicators for real-time channel health monitoring.
Hot-swappable design for maintenance without system downtime.
This module is vital for condition-based maintenance and machinery protection.
