The Bently Nevada 330701-00-30-10-01-00 is a high-performance 3300 XL 11 mm Proximity Probe designed for critical machinery condition monitoring. This transducer system utilizes eddy current technology to provide precise, non-contact measurements of shaft vibration and position in industrial rotating equipment.

Features

• Advanced Sensing Technology: Provides a 3.94 V/mm (100 mV/mil) output for high-resolution monitoring.
• Robust Construction: Features TipLoc and CableLoc technologies to ensure a strong bond between the probe tip and body, with a cable pull strength of 330 N (75 lbf).
• Environmental Sealing: Integrated Viton O-ring seals differential pressures between the probe tip and casing.
• ClickLoc Connectors: Gold-plated brass connectors ensure a secure, vibration-resistant electrical connection.
• RFI/EMI Immunity: Designed for high immunity to radio frequency interference, ensuring accurate readings in high-noise industrial environments.

Applications

• Reciprocating Compressors: Detection of rider band wear via piston rod drop and position monitoring.
• Centrifugal Compressors: High-speed shaft vibration and radial position measurement.
• Large Pumps & Motors: Shaft-to-bearing gap measurement for asset protection.
• Hydroelectric Generators: Reliable operation in environments requiring sealing against liquids and gases.
• Steam Turbines: Differential expansion monitoring to track rotor-casing growth during thermal cycles.

Technical Specifications

Installation Guidelines

• Ensure the probe is installed in a location free from excessive mechanical stress.
• Use appropriate mounting brackets to maintain the required gap distance from the target surface.
• When replacing 7200-series systems, all components including the Proximitor sensor and extension cables must be upgraded to 3300 XL 11 mm compatible hardware.
• Ensure the monitoring system configuration software is updated to recognize the 3300 XL 11 mm transducer system.
• Handle with care to avoid damage to the probe tip or the delicate coaxial connector pins.

FAQ

What is the primary function of this probe?

This probe measures the distance (gap) between the probe tip and a rotating metallic surface, allowing the monitoring system to calculate shaft vibration and radial position.

Is this probe compatible with older 7200-series systems?

No, the 3300 XL 11 mm system is not directly interchangeable with 7200-series components. A full system upgrade, including the Proximitor sensor and associated cabling, is required.

What is the typical gap voltage for this probe?

The system is typically set for a nominal gap voltage of approximately -10 VDC for standard operation.
