Original Bently Nevada 330910-05-25-10-02-00 Probe

Product Overview

The Bently Nevada 330910-05-25-10-02-00 is a high-precision 3300 NSv proximity probe designed for radial vibration and axial position monitoring in confined industrial spaces. Optimized for centrifugal and reciprocating compressors, it provides superior side-view suppression and high chemical resistance.

This model features a 1.0-meter total length and integrated stainless steel armor. It is 100% interchangeable with legacy 3300 RAM systems, ensuring reliable, non-contact monitoring for critical machinery protection.

Technical Specifications

Installation Guide

Gap Setting

Set the installation gap to 1.0 mm (40 mils), which typically outputs -9 Vdc. This ensures operation within the optimal linear range.

Torque

Recommended torque for M10X1 cases is 11.3 N·m (100 in·lb). Do not exceed the maximum rated torque of 33.9 N·m.

Cable Radius

Maintain a minimum bend radius of 25.4 mm (1.0 in) to protect the armored cable and ensure signal integrity.

Engineering Advantages

The 3300 NSv series excels in "Narrow System" targets. Its PPS tip resists corrosive fluids, and its advanced side-view characteristics eliminate interference from surrounding metal, providing clean vibration data for critical TSI systems.

Technical FAQs

Q1: How to verify probe health?

A1: Resistance for this 1.0m probe must be 4.2 ± 0.5 Ω between center conductor and shield.

Q2: Compatible with 3300 RAM?

A2: Yes, it is electrically and mechanically interchangeable with previous 3300 RAM series.

Q3: Required Proximitor?

A3: Must be used with a 3300 XL NSv Proximitor for accurate 200 mV/mil scaling.
