Description

Bently 3300/50-02-01-00-00 Shaft Vibration Monitoring Module

Product Dimensions：

The Bently Nevada 3300/50-02-01-00-00 is a high-precision Dual Tachometer Monitor, part of the classic 3300 Series Monitoring System. It is designed to measure shaft rotational speed and provide critical machine protection by monitoring for overspeed or underspeed conditions.

Product Detailed Description

The 3300/50 Dual Tachometer Monitor is a rack-mounted module that processes signals from Proximitor® sensors or magnetic pickups. It can be configured to measure speed, zero speed, or reverse rotation. The specific part number 3300/50-02-01-00-00 indicates a specific configuration regarding agency approvals and internal barrier options.

Technical Parameters

Product Advantages

• High Reliability: Proven track record in “Mission Critical” machinery protection; the 3300 series is known for decades of stable service in extreme industrial environments.
• Dual Channel Redundancy: Two independent channels allow for redundant speed monitoring or the monitoring of two separate machine shafts within one module.
• Flexible Configuration: Can be programmed for various functions including speed, peak speed (highest speed reached), and setpoint alarms.
• Integrated Display: The front panel features a bright digital display for real-time speed monitoring without the need for an external HMI.

Important Considerations & Precautions

• Transducer Gap: Accurate speed readings depend on the correct gap setting of the proximity probe relative to the notched shaft or gear tooth.
• Keyphasor® Compatibility: While it measures speed, it is often used in conjunction with a Keyphasor® signal to provide a timing reference for vibration analysis.
• Maintenance Bypass: When testing or calibrating the monitor, ensure the “Rack Alarm Inhibit” is used to prevent accidental machine trips (shutdowns).
• Obsolescence Note: The 3300 series has been largely succeeded by the 3500 series. Ensure spare parts are sourced from reputable vendors to guarantee genuine components.

Product Applications

The Bently Nevada 3300/50 is essential for protecting large-scale rotating machinery:

• Steam & Gas Turbines: Critical overspeed protection to prevent catastrophic mechanical failure.
• Centrifugal Compressors: Monitoring shaft speed to ensure the machine stays within its safe operating envelope.
• Electric Motors & Generators: Tracking rotational speed for synchronization and performance monitoring.
• Pumps & Fans: General speed monitoring in power plants and refineries.
