Description

Technical Overview

The Bently Nevada 330881-28-05-080-00-02 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 to meet stringent API 670 (4th Edition) and ISO 10816 standards, this transducer delivers exceptional signal integrity, thermal stability, and long-term repeatability—ensuring reliable shaft vibration, axial position, and differential expansion measurements under demanding operational conditions.

Unlike legacy modular systems, the PROXPAC XL integrates the probe, extension cable, and前置 amplifier into a single calibrated assembly, eliminating field calibration drift and reducing installation complexity. Its advanced eddy-current sensing technology operates at 1 MHz, providing sub-micron resolution and a linear range of ±80 mils (±2.03 mm) with less than ±1% linearity error across the full temperature range of –40°C to +125°C ambient. The transducer features robust 316 stainless steel construction, hermetic sealing, and MIL-C-5015 compliant connectors, making it ideal for harsh environments with exposure to moisture, hydrocarbons, and electromagnetic interference.

Key Features

• Factory-Calibrated Integrated Assembly: Probe, cable, and amplifier pre-matched and calibrated as a single unit—ensures zero setup error and eliminates field recalibration requirements.
• Extended Temperature Stability: Maintains accuracy across –40°C to +125°C ambient without performance degradation or signal drift.
• API 670 Compliance: Fully certified for use in safety-critical machinery protection systems per API RP 670 (4th Ed.) and IEC 61508 SIL 2 capable configurations.
• High Immunity to EMI/RFI: Shielded coaxial design and differential output minimize noise coupling in electrically noisy plant environments.
• Quick-Connect Interface: Standardized 3-pin MIL-C-5015 connector enables rapid, repeatable field installation and replacement with no tooling required.
