Description

Technical Overview

The Bently Nevada 330105-02-12-05-02-01 is a high-precision, reverse-mount proximity probe engineered for demanding industrial machinery protection and condition monitoring applications. As part of the trusted 3300 XL 8 mm sensor family, this probe delivers exceptional stability, repeatability, and immunity to environmental interference—including temperature fluctuations, electromagnetic noise, and oil mist—making it ideal for critical rotating equipment in power generation, oil & gas, petrochemical, and heavy manufacturing facilities. Its reverse-mount configuration enables compact installation in space-constrained bearing housings or machine frames where traditional front-mount probes are impractical.

Designed to interface seamlessly with Bently Nevada 3300 XL series monitors (e.g., 3300 XL 25 mm and 3300 XL 50 mm systems), the 330105-02-12-05-02-01 maintains full compatibility with existing 3300 infrastructure, ensuring straightforward integration, consistent calibration, and reliable data correlation across multi-probe measurement setups. The probe utilizes advanced eddy-current technology with a precisely tuned 8 mm diameter active sensing area, providing optimal sensitivity for shaft vibration, axial position, and differential expansion measurements within ±2.0 mm linear range. Its robust stainless steel housing and PTFE-insulated cable meet stringent IP67 ingress protection standards, supporting long-term reliability in harsh, high-vibration industrial environments.

Key Features

• Reverse-Mount Design: Enables secure, low-profile installation behind mounting surfaces—ideal for retrofits and confined spaces without compromising signal integrity.
• 3300 XL System Compatibility: Fully interoperable with Bently Nevada’s industry-standard 3300 XL monitoring platforms, including seamless integration with 3300 XL 25 mm and 50 mm monitors and preamplifiers.
• High-Stability Sensing: Precision-machined 8 mm probe tip with optimized coil geometry ensures minimal thermal drift (<0.05% FS/°C) and excellent linearity over its calibrated range.
• Ruggedized Construction: 316 stainless steel probe body, high-temperature PTFE cable jacket (rated to 200°C), and hermetically sealed connector ensure durability in extreme operating conditions.
• Factory-Calibrated & Traceable: Supplied with NIST-traceable calibration certificate and individual serial-numbered documentation for compliance with ISO 17025 and API 670 requirements.
