Description

Technical Overview

The Bently Nevada 330881-16-05-035-01-02 PROXPAC XL Proximity Transducer is a high-precision, ruggedized sensing solution engineered for continuous vibration and position monitoring in mission-critical rotating machinery. Designed for integration into Bently Nevada’s System 1™ and 3500/40M monitoring platforms, this transducer delivers exceptional linearity, thermal stability, and long-term repeatability across demanding industrial environments—including power generation, oil & gas, petrochemical, and heavy manufacturing applications. Its advanced eddy-current technology enables non-contact measurement of shaft displacement, runout, and axial position with sub-micron resolution, ensuring early detection of mechanical anomalies such as imbalance, misalignment, bearing wear, and rub conditions.

Featuring an extended temperature operating range (–40 °C to +125 °C) and IP67-rated stainless steel housing, the 330881-16-05-035-01-02 maintains signal integrity under extreme thermal cycling, high humidity, and corrosive atmospheres. The integrated coaxial cable and hermetically sealed connector ensure robust EMI/RFI immunity—critical for reliable operation near variable frequency drives (VFDs), switchgear, and high-voltage equipment. Calibration traceability to NIST standards and compliance with API 670 (4th Edition) and ISO 10816 further validate its suitability for condition-based maintenance (CBM) and predictive maintenance (PdM) programs mandated by industry regulators and asset integrity frameworks.

Key Features

• High-Accuracy Eddy-Current Sensing: Delivers ±0.5% full-scale linearity and <±1% thermal drift over operating temperature range for dependable shaft displacement data.
• Ruggedized Industrial Design: Stainless steel probe body, integral 5-meter low-noise coaxial cable, and MIL-C-39012 compatible connector ensure durability in harsh mechanical and environmental conditions.
