Description

Technical Overview

The Bently Nevada 330881-28-05-060-00-02 PROXPAC XL Proximity Transducer is a high-performance, factory-integrated proximity measurement solution engineered for mission-critical rotating machinery monitoring in power generation, oil & gas, chemical processing, and heavy industrial applications. Designed as part of the industry-standard 3300 XL family, this transducer delivers exceptional stability, repeatability, and immunity to electromagnetic interference (EMI) — essential for reliable vibration and position monitoring in harsh plant environments. Its robust construction features a stainless steel housing and high-temperature cable assembly rated for continuous operation up to +125°C, ensuring long-term reliability even under extreme thermal and mechanical stress.

Unlike legacy proximity systems requiring separate probe, extension cable, and driver components, the PROXPAC XL integrates the probe and preamplifier into a single, calibrated, field-ready unit — significantly reducing installation time, calibration complexity, and potential failure points. The transducer operates on the well-established eddy-current principle and is compatible with all Bently Nevada 3300/3500 series monitors and System 1™ diagnostic platforms. It supports standard 4–20 mA and voltage output configurations, enabling seamless integration into existing DCS, PLC, and condition monitoring infrastructures without costly system upgrades.

Key Features

• Integrated Probe-Preamplifier Design: Eliminates need for separate extension cables and external drivers — reduces installation errors and improves signal integrity.
• High-Temperature Capability: Rated for continuous operation up to +125°C ambient, making it ideal for turbine casings, compressors, and gearboxes.
• Factory-Calibrated & Matched: Supplied with NIST-traceable calibration certificate; guaranteed linear range and sensitivity per API 670 standards.
• EMI/RFI Immunity: Engineered to meet IEC 61000-4-3 and MIL-STD-461F requirements for operation in electrically noisy environments.
• Corrosion-Resistant Construction: 316 stainless steel probe tip and housing ensure durability in humid, saline, or chemically aggressive atmospheres.
