Bently Nevada 330101-00-20-05-02-CN 3300 XL Probe

Product Overview

The Bently Nevada 330101-00-20-05-02-CN is a high-precision 3300 XL 8 mm proximity probe designed for continuous vibration, position, and shaft displacement monitoring on critical industrial machinery. Manufactured in the U.S.A., this eddy current field transducer outputs a linear electrical signal proportional to the gap between the probe tip and a conductive target shaft (such as in steam turbines, centrifugal compressors, and large pumps).

Configured with a 3/8-24 UNF threaded casing without armor, this specific model features a 0.0-inch unthreaded length, a 2.0-inch total case length, and a 0.5-meter (1.6 feet) integral standard cable. Terminated with a miniature coaxial ClickLoc connector and backed by country-specific (CN) agency approvals, it delivers dependable performance in severe plant environments.

Core Technical Advantages

• Miniature ClickLoc Coaxial Interface: Gold-plated ClickLoc connector ensures a tight mechanical connection to prevent fluid intrusion and vibration looseness.
• Country-Specific Approvals (CN): Pre-certified under country-specific compliance frameworks for local industrial safety regulations.
• Wide Operating Temperature: Performs reliably across extreme thermal swings from -51°C to +177°C.
• Compact 0.5m Integral Lead: Minimizes cable slack inside tight bearing housings for direct connection to extension cables.

Technical Specifications

Installation & Gap Calibration Guide

• Mounting: Screw the 3/8-24 UNF casing into the tapped bearing port until close to the target shaft.
• Gap Setting: Adjust probe depth while monitoring Proximitor DC gap voltage until it reaches the target midpoint (typically -10.0 VDC), then secure with the locknut.
• Cable Protection: Route the coaxial lead clear of moving parts, maintaining proper bend radius to protect the cable.
