Description

Technical Overview

The Bently Nevada 330104-03-12-10-02-00 is a high-precision, non-contact eddy-current proximity probe engineered for critical machinery health monitoring in demanding industrial environments. As part of the trusted 3300 XL 8 mm sensor family, this probe delivers exceptional linearity, temperature stability, and long-term repeatability—essential for reliable shaft vibration, axial position, and differential expansion measurements in rotating equipment such as turbines, compressors, motors, and generators. Its robust 8 mm diameter sensing tip ensures optimal signal-to-noise ratio and reduced sensitivity to target material variations, making it ideal for use with standard 400-series stainless steel targets.

Designed for seamless integration with Bently Nevada 3300 XL monitoring systems—including the 3300 XL 25 mm and 50 mm extension cables and 3300 XL Proximitor transducers—this probe adheres to API 670 (4th Edition) standards for machinery protection systems. The probe’s hermetically sealed, corrosion-resistant construction features a PPS (polyphenylene sulfide) housing and high-temperature epoxy encapsulation, enabling continuous operation in harsh conditions up to 120°C ambient temperature. Its low-drift electronics and optimized coil geometry minimize thermal drift and phase shift, ensuring consistent performance across wide operating temperature ranges and extended service intervals.
