330903-00-04-10-01-00 Bently Nevada Proximity Probe

Technical Specifications

Product Overview

The Bently Nevada 330903-00-04-10-01-00 is a high-precision 3300 NSv Proximity Probe engineered for critical shaft vibration and position tracking inside centrifugal process compressors. Weighing a lightweight 0.13 kg, this industrial eddy current sensor features a 40mm stainless steel case length with an unarmored M8 × 1 metric thread housing and a 1.0-meter integral standard cable. It provides complete mechanical and electrical backward compatibility with legacy 3300 RAM setups while delivering upgraded chemical resistance required for harsh compressor environments.

Core Technical Advantages

• Enhanced Chemical Immunity: Specifically optimized to survive the aggressive gases, corrosive synthetic lubricants, and heavy process washes typical of industrial compressor setups.
• Precise High-Frequency Telemetry: Features a factory-calibrated 10 kHz frequency response paired with a low ±0.06mm linearity deviation over its active 0.25-1.75mm detection range.
• Consistent Scale Linearization: Maintains an absolute 7.87 V/mm (200 mV/mil) sensitivity output, delivering predictable displacement data across the entire monitoring window.
• ClickLoc Coaxial Connection: This compact 0.13 kg assembly incorporates a miniature coaxial ClickLoc connection terminal sleeve with a protector shield to guarantee a moisture-proof, vibration-stable signal path.

Installation Guide

Thread the M8 × 1 probe case into the machine housing layout, observing a maximum thread engagement depth of 12 mm. Set the baseline air gap setting over a target area with a minimum diameter of 8.9 mm. Torque the 0.13 kg transducer structure to the recommended 5.1 N·m installation rating, keeping the probe cable bend radius above the 25.4 mm safety floor. Extended field wiring runs up to 305 meters are supported back to the monitoring rack.

Technical FAQs

Q1: Is the 330903-00-04-10-01-00 compatible with older Bently Nevada hardware series?
A1: Yes. The 3300 NSv probe body is fully compatible and interchangeable with Bently Nevada's previous 3300 RAM proximity probe systems for seamless field upgrades.

Q2: What do the "-00-04-" option digits indicate about this model?
A2: The option codes confirm this probe is engineered with 00 mm of unthreaded barrel length and an overall case thread depth of exactly 40 mm.

Q3: Does this proximity probe feature international hazardous area approvals?
A3: No. The terminal "00" option suffix denotes a standard, uncertified electrical configuration intended for environments where specialized agency approvals are not required.
