Bently Nevada 330103-01-07-50-02-00 3300 XL 8 mm Proximity Probe

Description

Option 01 (0.1 in unthreaded length), Option 07 (0.7 in case length), Option 50 (5.0 m total length), Option 02 (Miniature ClickLoc connector, standard cable), and Option 00 (no agency approval required) define this 330103-01-07-50-02-00 3300 XL 8 mm proximity probe configuration. This non-contact, eddy-current transducer system is designed for critical machinery protection, providing accurate shaft vibration and axial position measurements in demanding industrial environments. The 330103 series features an M10 x 1 thread and a non-armored cable design. It is fully compatible with the Bently Nevada 3300 XL Proximitor sensor and extension cables, forming a complete measurement chain that transmits proportional voltage signals to monitoring systems like the 3500 or 3300 series. This specific configuration is optimized for installations where a specific probe length and unthreaded section are required to match mechanical clearances and installation spacing in turbomachinery or centrifugal compressors.

Features

• M10 x 1 thread design (330103 series) without armor
• 5.0 meter total system length optimized for 5-meter Proximitor sensor compatibility
• Miniature coaxial ClickLoc connector for reliable, secure termination
• Standard cable construction without protective armor
• Non-contact measurement of shaft vibration and position
• Backward compatible with existing 3300 series transducer systems

Applications

• Radial vibration and axial position monitoring in rotating machinery
• Critical machinery protection for steam, gas, and hydro turbines
• Centrifugal and axial compressor vibration analysis
• General purpose industrial monitoring for pumps, blowers, and fans

Installation Guidelines

• Ensure the probe is gapped correctly according to the machine monitor requirements (typically -10V to -12V DC at center gap).
• Use appropriate probe mounting brackets (e.g., 137491 or 137492 series) for M10 threads.
• Ensure the coaxial cable is routed away from high-voltage lines to prevent electromagnetic interference (EMI).
• Do not over-tighten probe lock nuts; ensure the probe is securely tightened to prevent vibration loosening.
• Protect all connectors using connector protectors or silicone self-fusing tape if the environment contains moisture or contaminants.
