Bently Nevada 330101-00-65-50-02-CN 3300 XL Proximity Probe

Description

To monitor shaft vibration and axial position in critical rotating machinery, the 330101-00-65-50-02-CN serves as a high-precision sensor component within the 3300 XL 8mm Transducer System. This eddy current proximity probe provides continuous, non-contact displacement measurements by generating a radio frequency field that detects the distance between the probe tip and the target conductive surface.

The mechanical configuration of this model features a 3/8-24 UNF thread design without protective armor. It is specified with an unthreaded length of 0.0 inches and an overall case length of 6.5 inches. Engineered for long-term reliability in demanding industrial environments, the probe assembly includes a standard coaxial cable equipped with a ClickLoc miniature coaxial connector, ensuring low-loss connection integrity to the system extension cable.

Features

• Non-contact eddy current measurement principle minimizes wear and mechanical lag.
• Robust thread design without armor allows for direct installation in threaded ports.
• ClickLoc miniature coaxial connector provides a secure connection resistant to vibration-induced loosening.
• Fully compatible with standard Bently Nevada 3300 XL series Proximitor sensors.
• Designed for harsh environmental operations, maintaining signal stability across temperature swings.

Applications

• Steam turbine shaft vibration and axial displacement monitoring.
• Centrifugal compressor oil film bearing clearance tracking.
• Power generation alternator shaft position analysis.
• Industrial gearbox and high-speed blower monitoring.

Connections and Interfaces

Installation Guidelines

• Maintain a perpendicular orientation between the probe tip and the target shaft surface to avoid cross-axis measurement errors.
• Ensure target area clearance meets Bently Nevada guidelines to eliminate side-viewing interference from adjacent metal structures.
• Torque the probe mounting threads to standard engineering limits to prevent thread stripping or probe casing deformation.
• Protect the coaxial connector union with an appropriate connector silicone boot kit to prevent fluid ingress and signal shorting.

Compliance and Certifications

• CN country-specific hazardous area certifications.
• CE compliant.
