Description

Technical Overview

The Bently Nevada 330101-38-49-20-02-05 is a high-precision 3300 XL 8 mm proximity probe engineered for mission-critical machinery monitoring in demanding industrial environments. As part of the industry-standard 3300 XL series, this probe delivers exceptional linearity, thermal stability, and long-term repeatability—essential for reliable vibration, displacement, and position measurements in rotating equipment such as turbines, compressors, motors, and gearboxes. Its robust stainless steel construction and hermetically sealed design ensure consistent performance under extreme temperatures, high humidity, oil immersion, and electromagnetic interference commonly encountered in power generation, oil & gas, and heavy manufacturing facilities.

Designed for seamless integration with the 3300 XL 8 mm proximitor transducers and system monitors, the 330101-38-49-20-02-05 operates on eddy-current technology to provide non-contact, wear-free sensing with a nominal 8 mm sensing range. The probe’s optimized coil geometry and precision-machined tip deliver superior resolution (≤ 0.25 µm) and a linear output across its full dynamic range, enabling early detection of shaft misalignment, bearing wear, and rotor instability. Its calibrated sensitivity of 7.87 V/mm (200 mV/mil) ensures compatibility with legacy and modern Bently Nevada monitoring systems, supporting predictive maintenance strategies and compliance with ISO 10816 and API 670 standards.

Key Features

• High-Accuracy Sensing: 8 mm nominal range with ±1% linearity and sub-micron resolution for precise shaft displacement and vibration analysis.
• Rugged Industrial Design: 316 stainless steel body, PTFE-insulated cable, and IP68-rated environmental protection for operation in harsh, high-vibration, and chemically aggressive settings.
• System Compatibility: Fully interoperable with 3300 XL 8 mm proximitors (e.g., 330180-50-00), 3500/40M monitors, and Asset Management Systems (AMS).
• Factory-Calibrated & Traceable: Supplied with NIST-traceable calibration certificate and individual serial-numbered documentation for audit-ready compliance.
• Long-Term Reliability: Designed for >10-year service life with minimal drift (<0.1% FS/year), reducing recalibration frequency and total cost of ownership.
