Description

Technical Overview

The Bently Nevada 330881-28-00-125-00-02 is a high-precision PROXPAC XL Proximity Transducer engineered for mission-critical machinery protection and condition monitoring in demanding industrial environments. Designed to meet stringent API 670 (4th Edition) and ISO 10816 standards, this transducer delivers exceptional stability, repeatability, and immunity to electromagnetic interference—making it ideal for turbomachinery, compressors, steam and gas turbines, and large electric motors. Its advanced eddy-current sensing technology enables non-contact measurement of shaft vibration, axial position, and differential expansion with sub-micron resolution across extended temperature ranges.

Integrated into Bently Nevada’s System 1™ and 3500/40M monitoring platforms, the 330881-28-00-125-00-02 features a robust, hermetically sealed stainless steel housing rated IP67 for reliable operation in harsh conditions—including high humidity, oil mist, and ambient temperatures from –40°C to +125°C. The transducer utilizes a precision-machined probe tip and optimized coil geometry to minimize thermal drift and ensure long-term calibration integrity. Its low-noise, wide-bandwidth output (DC to 10 kHz) supports both real-time protection logic and high-fidelity diagnostic analysis, enabling predictive maintenance strategies that reduce unplanned downtime and extend asset life.

Key Features

• API 670–Compliant Design: Certified for use in critical machinery protection systems per latest edition requirements.
• Extended Temperature & Environmental Rating: Operates reliably from –40°C to +125°C; IP67-rated housing resists dust, moisture, and oil ingress.
• High-Fidelity Signal Output: Low-noise, wide-frequency response (DC–10 kHz) ensures accurate capture of vibration, position, and gap signals.
• Plug-and-Play Integration: Fully compatible with Bently Nevada 3500, 3300 XL, and System 1 platforms—no field recalibration required.
• Long-Term Stability: Precision-wound probe coil and thermally matched materials minimize drift over time and temperature cycles.
