Bently Nevada 330910-05-25-10-02-00 3300 NSv Proximity Probes

Description

Option 05 (50 mm unthreaded length) and Option 25 (250 mm overall case length) specify this 3300 NSv proximity probe configuration — 330910-05-25-10-02-00 3300 NSv proximity probe. This metric-threaded, standard-mount probe features an M10x1 thread style with integrated stainless steel armor, making it suitable for applications with physical or mechanical hazards. It has a 1.0 m (39 in) total cable length terminated with a miniature coaxial ClickLoc connector, and requires no hazardous area agency approvals (Option 00).

The 330910-05-25-10-02-00 probe is used in restricted-space installations where standard 5 mm or 8 mm systems cannot fit due to small target sizes or minimal side clearances. When used as part of a complete 3300 XL NSv transducer system, which includes a 330980 Proximitor sensor and a 330930 extension cable, it measures non-contact shaft vibration and axial displacement. Its TipLoc molding provides a secure seal between the probe tip and case, while the CableLoc design offers 220 N (50 lb) of pull strength to withstand demanding machinery environments.

Features

• Option 05 designates a 50 mm unthreaded length for custom mounting depth configurations.
• Option 25 specifies a 250 mm overall case length with an M10x1 metric thread pattern.
• Option 10 provides a 1.0 meter (39 inches) total cable length for routing directly to an extension cable.
• Option 02 equips a miniature coaxial ClickLoc connector on standard, non-FluidLoc cable.
• Option 00 denotes that agency approval certifications are not required.
• Stainless steel armor provides physical protection against impact, abrasion, and debris.
• TipLoc molding technology creates a cohesive, high-strength bond between the PPS probe tip and the brass case.
• CableLoc design delivers up to 220 N (50 lb) of cable pull strength.

Applications

• Small-bore rotating machinery monitoring including high-speed compressors, pumps, and fans.
• Aeroderivative gas turbine vibration and axial position measurement.
• High-speed machinery with limited target geometry where standard probes encounter cross-talk or side-view limitations.
• Tight clearance thrust and radial displacement measurements in general-purpose industrial environments.

Installation Guidelines

• Target Alignment: Ensure the target size is at least 13 mm (0.5 in) in diameter. Small shaft diameters or target sizes will affect the scale factor; gapping closer may be required to offset this.
• Probe Threading: Mount standard-mount probes securely using M10x1 threaded holes. Avoid excessive thread engagement lengths to prevent binding during installation.
• Connector Protection: Use a connector protector on the probe-to-extension cable connection to prevent oil and liquid ingress. Slide the protector over the connection until it locks into position.
• Armor Routing: Route the armored cable carefully to avoid sharp bends. The stainless steel armor prevents mechanical damage but requires a minimum bend radius to protect internal coaxial conductors.
• System Matching: Verify that the total length of the probe (1.0 m) combined with the extension cable equals the Proximitor sensor's calibrated system length (typically 5.0 m or 7.0 m).

Compliance and Certifications

This general-purpose configuration is optioned without hazardous area certification requirements (Option 00). It is designed for standard, non-classified industrial environments.
