Description

Technical Overview

The Bently Nevada 330881-28-00-070-03-02 PROXPAC XL Proximity Transducer is a high-precision, ruggedized industrial sensing solution engineered for continuous, non-contact vibration and position monitoring in critical rotating machinery applications. Designed to meet the stringent demands of power generation, oil & gas, petrochemical, and heavy industrial environments, this transducer delivers exceptional signal stability, thermal drift compensation, and long-term reliability—even under extreme temperature fluctuations, electromagnetic interference (EMI), and mechanical shock.

As part of the trusted PROXPAC XL family, the 330881-28-00-070-03-02 integrates advanced eddy-current technology with a compact, hermetically sealed stainless-steel housing rated for harsh process conditions. It operates seamlessly with Bently Nevada 3500/40M, 3500/45M, and System 1™ monitoring platforms, providing accurate displacement measurements across a standard 0–70 mil (0–1.78 mm) linear range. Its optimized frequency response (0–10 kHz) ensures fidelity for both low-frequency shaft orbit analysis and high-frequency fault detection—including bearing defects, imbalance, misalignment, and rubs.

Key Features

• High-Stability Eddy-Current Sensing: Precision-matched probe and extension cable ensure consistent sensitivity and minimal phase shift over time and temperature.
• Robust Industrial Construction: Stainless-steel probe tip and body with IP68-rated sealing for resistance to moisture, oil, dust, and corrosive atmospheres.
• Plug-and-Play Compatibility: Fully compliant with Bently Nevada’s 3500 series monitors and System 1™ software—no field calibration required when used with certified PROXPAC XL components.
• Extended Temperature Range: Operates reliably from –40 °C to +125 °C ambient, supporting deployment in turbine enclosures, compressor skids, and offshore platforms.
• EMI/RFI Immunity: Engineered with integrated shielding and differential output circuitry to maintain signal integrity in electrically noisy plant environments.
