Bently Nevada 3300 NSv 330908-00-19-10-02-05 Probe

Product Overview

The Bently Nevada 330908-00-19-10-02-05 is a premium 3300 NSv series eddy current proximity probe designed for critical shaft vibration and displacement monitoring in tight mechanical clearances. Featuring a 3/8-24 UNF unarmored thread configuration with a 0-inch unthreaded length and a 1.9-inch overall case length, this transducer is built with a rugged AISI 304 stainless steel case and a high-performance Polyphenylene Sulfide (PPS) probe tip. 

Technical Specifications

Installation & Handling Guidelines

Torque Limits: For the 3/8-24 probe case installation, the recommended tightening torque is 11.3 N·m (100 in·lb), with a maximum rated limit of 33.9 N·m (300 in·lb). Ensure maximum thread engagement does not exceed 0.563 inches. For connector-to-connector setup, use finger-tight or a maximum of 0.56 N·m (5 in·lb).
Physical Constraints: Maintain a minimum cable bend radius of 25.4 mm (1.0 inch) to prevent internal short circuits. The target area diameter must meet a absolute minimum of 8.9 mm (0.35 in), though 13 mm (0.5 in) is highly recommended to protect the integrity of the scale factor.

Technical FAQs

Q1: Is this probe compatible with older Bently Nevada proximity systems?

A1: Yes. The 3300 NSv probe is mechanically and electrically compatible and interchangeable with the legacy 3300 RAM proximity probe series, while offering superior chemical resistance.

Q2: What are the exact voltage parameters across its linear range?

A2: The 1.5 mm (60 mils) linear range spans from approximately 0.25 mm to 1.75 mm (10 to 70 mils) away from the target, translating to an electrical output of roughly -1 to -13 Vdc.

Q3: What type of environment is the pressure seal designed for?

A3: The integrated Viton O-ring seals differential pressure between the probe tip and case. However, please note that these standard probes are not custom pressure-tested prior to factory shipment.
