Bently Nevada 330910-03-09-05-02-05 Proximity Probe

Product Overview

The Bently Nevada 330910-03-09-05-02-05 is a high-precision 3300 NSv Proximity Probe designed for non-contacting displacement and vibration measurements. Optimized for process compressor applications, the NSv (Narrow Side View) series offers superior chemical resistance and lateral clearance characteristics compared to standard RAM probes.

This specific configuration features an M10 x 1 metric thread, integrated stainless steel armor, and a 0.5-meter cable with a ClickLoc™ miniature coaxial connector. With a typical probe weight ranging from 14 to 150 grams depending on the final assembly, it provides a stable 7.87 V/mm (200 mV/mil) incremental scale factor across a 1.5 mm linear range.

Technical Specifications

Key Performance Features

• Enhanced Material Durability: The probe tip is made from Polyphenylene sulfide (PPS) and the case from AISI 304 Stainless Steel (SST), offering exceptional resistance to process chemicals.
• Precise Measurement: Maintains an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil) with a deviation from best fit straight line (DSL) of less than ±0.06 mm.
• High-Temperature Operation: Designed to operate reliably in extreme conditions from -52°C to +177°C (-62°F to +351°F).
• Advanced Pressure Sealing: Features a Viton® O-ring designed to seal differential pressure between the probe tip and the case, critical for compressor internals.

Installation & Electrical Data

The 330910-03-09-05-02-05 probe has a DC resistance of 4.0 ± 0.5 Ω from center conductor to outer conductor for the 0.5m length. During installation, the recommended gap setting is 1.0 mm (40 mils). The maximum rated torque for the M10 case is 33.9 N•m (300 in•lb), though 11.3 N•m (100 in•lb) is recommended for standard secure mounting.

Technical FAQs

Q1: What is the benefit of the ClickLoc™ connector?
A1: The ClickLoc™ is a miniature coaxial interface that provides a secure, vibration-resistant connection while maintaining impedance stability across the measurement circuit.

Q2: Is this probe interchangeable with older 3300 RAM models?
A2: Yes, it is both mechanically and electrically compatible with previous 3300 RAM proximity probes and extension cables.

Q3: What target size is required for accurate measurement?
A3: A flat target with a minimum diameter of 8.9 mm (0.35 in) is required, though 13 mm (0.5 in) is recommended for optimal scale factor stability.
