Description

Technical Overview

The Bently Nevada 330881-28-00-265-00-02 PROXPAC XL Proximity Transducer is a high-precision, ruggedized industrial sensing solution engineered for continuous vibration and position monitoring in critical rotating machinery applications. Designed for integration into Bently Nevada’s System 1™ and 3500/40M monitoring platforms, this transducer delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—ensuring reliable performance in harsh plant environments including power generation, oil & gas, petrochemical, and heavy manufacturing facilities.

Utilizing advanced eddy-current technology, the 330881-28-00-265-00-02 provides non-contact measurement of shaft displacement, radial vibration, axial position, and differential expansion with sub-micron resolution. Its PROXPAC XL architecture incorporates optimized probe-to-extension cable matching, factory-calibrated sensitivity (typically 7.87 V/mm or 200 mV/mil), and integrated temperature compensation to minimize drift across operating temperatures from –30°C to +120°C. The transducer’s stainless steel housing and hermetically sealed construction meet IP67 ingress protection standards, ensuring long-term reliability in high-humidity, dusty, or corrosive atmospheres.

Key Features

• High-Accuracy Eddy-Current Sensing: Delivers repeatable, low-noise output with ≤±1% system linearity error over full measurement range.
• Integrated PROXPAC XL Architecture: Combines probe, extension cable, and前置 amplifier in a single calibrated assembly—eliminating field calibration and reducing installation errors.
• Rugged Industrial Design: Stainless steel probe body, PTFE-insulated coaxial cable, and wide-temperature operation ensure durability in demanding mechanical and environmental conditions.
• EMI/RFI Immunity: Meets IEC 61000-4-3 (Radiated Immunity) and IEC 61000-4-6 (Conducted Immunity) standards for stable operation near VFDs, switchgear, and high-power motors.
• Direct Compatibility: Seamlessly interfaces with Bently Nevada 3500/40M, 3500/22M, and System 1™ platforms—supporting standard 4–20 mA and voltage output configurations.
