330901-00-30-10-02-00 Bently Nevada High Precision Vibration Probe

Product Overview

The Bently Nevada 330901-00-30-10-02-00 is a high-precision 3300 NSv (Narrow System) proximity probe engineered for vibration monitoring in tight-clearance industrial applications. Specifically optimized for small centrifugal compressors and high-speed turbomachinery, this eddy current sensor provides reliable non-contact measurement where standard 8mm probes cannot be installed. With its 1/4-28 UNF thread and PPS tip construction, it delivers exceptional linear accuracy and chemical resistance for critical shaft vibration and position analysis.

Technical Configuration

Engineered for precision fit in restricted mechanical spaces:

• Model Series: 3300 NSv Probe (1/4-28 UNF thread, No Armor)
• Unthreaded Length: 0.0 in
• Overall Case Length: 3.0 in
• Total System Length: 1.0 Meter (39 in)
• Connector: Miniature coaxial ClickLoc connector (Standard Cable)
• Approvals: 00 (Standard Agency Approval)

Technical Specifications

Engineering Advantages

The 3300 NSv system utilizes a high-durability PPS (Polyphenylene Sulfide) tip for superior insulation and resistance to industrial fluids. The ClickLoc connector prevents accidental disconnection due to high-frequency vibration, ensuring signal stability. Furthermore, the Viton O-ring integration provides a robust pressure seal between the probe tip and the case, safeguarding the machinery housing against differential pressure leaks during operation.

Technical FAQs

Q1: Why choose the 330901 NSv probe over a standard 8mm probe?
A1: The NSv series is specifically designed for applications with restricted installation space or small shaft diameters where a standard 8mm probe would be too large to fit.

Q2: What is the maximum thread engagement for this model?
A2: For the 1/4-28 thread case, the maximum length of thread engagement should not exceed 0.375 inches to ensure mechanical integrity.

Q3: How does the total length impact system calibration?
A3: This 1.0-meter probe must be used with a matching extension cable to reach the total electrical length (typically 5m or 7m) for which your NSv Proximitor sensor was calibrated.
