Product Overview

The Bently Nevada 3300/65 Keyphasor Module is a critical component within the 3300 Series rack-based monitoring system. It is engineered to capture once-per-turn reference pulses from rotating machinery shafts. By processing these signals, the module facilitates precise phase and speed measurements, which are essential for advanced vibration analysis, machinery diagnostics, and system synchronization. This specific configuration, 3300/65-13-01-00-00-01-00, includes integrated intrinsic safety barriers for deployment in hazardous environments.

Features

  • Provides reliable once-per-turn reference pulse generation.
  • Enables accurate phase angle and rotational speed monitoring.
  • Compatible with standard proximity probes and magnetic pickup inputs.
  • Includes internal intrinsic safety barriers to support hazardous area operations.
  • Optimized for integration with other 3300 series monitoring modules to support comprehensive machinery protection.

Applications

This module is widely employed in industrial turbomachinery protection systems, including steam turbines, gas turbines, compressors, and large centrifugal pumps where phase-referenced vibration data is required for predictive maintenance and fault diagnosis.
