Description
The Bently Nevada 3300/65 Keyphasor Module is a specialized component designed for the 3300 Series rack-based monitoring system. Its primary role is to process input signals from proximity probes or magnetic pickups, generating a once-per-turn reference pulse from a rotating shaft. This pulse is essential for calculating machine speed and phase angle, which are critical parameters for advanced vibration analysis and diagnostic monitoring of rotating equipment.
Features
- Provides accurate once-per-turn reference signals for phase and speed monitoring.
- Integrates seamlessly into the 3300 Series rack architecture.
- Includes an intrinsic safety barrier (specified by configuration code) for safe operation in hazardous environments.
- Facilitates synchronization for complex vibration monitoring and diagnostic tasks.
- Optimized for reliable signal conditioning in industrial environments.

Installation Guidelines
- Ensure the 3300 Series rack is de-energized before inserting or removing the module to prevent electrical damage.
- Verify that the module is fully seated in the rack slot to ensure proper backplane connection.
- Use shielded cabling for transducer inputs to minimize electromagnetic interference (EMI) and signal noise.
- Verify grounding requirements for hazardous area installations when utilizing the intrinsic safety barrier.
- Maintain proper ventilation within the rack to ensure operating temperatures remain within the specified -30 degC to +65 degC range.
FAQ
What is the primary function of the 3300/65 module?
The module serves as a Keyphasor, which provides a once-per-turn timing pulse to the monitoring system. This allows the system to determine the phase of vibration signals and calculate precise shaft speed.
Does this module support hazardous locations?
Yes, the inclusion of the intrinsic safety barrier (suffix 01) in this specific configuration allows for installation in designated hazardous environments, subject to local agency approval codes.
Can I use this for magnetic pickups?
Yes, the 3300/65 is designed to accept inputs from both proximity probes and magnetic pickups to generate the necessary reference pulses.
