Description

Technical Overview

The Bently Nevada 330881-28-05-070-00-02 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, and industrial manufacturing environments. Designed as part of the industry-leading PROXPAC XL family, this transducer combines a rugged 3300 XL 8 mm probe with an integrated, field-configurable signal conditioner housed in a single compact assembly—eliminating external cabling complexity and reducing installation time by up to 40%. Its advanced eddy-current technology delivers exceptional linearity (±0.5% full scale), low thermal drift (<0.05%/°C), and immunity to electromagnetic interference (EMI), ensuring stable, repeatable measurements even under extreme ambient temperatures (–30°C to +125°C) and high-vibration conditions.

Unlike legacy proximity systems requiring separate probes, extension cables, and前置 conditioners, the 330881-28-05-070-00-02 integrates all signal conditioning electronics directly behind the probe head. This architecture minimizes noise pickup, improves signal integrity over long cable runs (up to 300 m), and supports seamless integration with Bently Nevada 3500/4000 series monitors and System 1™ asset performance management software. The transducer is calibrated to meet API 670 (4th Edition) standards for vibration and position monitoring, making it ideal for compliance-driven applications such as turbine shaft displacement, bearing wear detection, and thrust position verification.

Key Features

• Integrated Design: Combines 8 mm probe and signal conditioner in one sealed, IP67-rated housing—no external modules or calibration kits required.
• Factory-Calibrated & Traceable: Supplied with NIST-traceable calibration certificate; zero-point and sensitivity pre-set for immediate deployment.
• Enhanced Environmental Resilience: Stainless steel construction, wide operating temperature range, and robust EMI/RFI shielding for harsh plant-floor conditions.
• Plug-and-Play Compatibility: Direct interface with Bently Nevada 3500/4000 monitors and compatible with legacy 3300 system infrastructure via standard 3300 XL connectors.
• Diagnostics-Ready: Supports live health monitoring, including probe continuity, bias voltage, and output saturation alerts via monitor communication protocols.
