Description

Technical Overview

The Bently Nevada 330881-28-00-150-03-02 PROXPAC XL Proximity Transducer is a high-precision, ruggedized industrial sensing solution engineered for continuous, non-contact vibration and displacement monitoring in mission-critical rotating machinery. Designed for integration into Bently Nevada’s 3500/40M and System 1™ platforms, this transducer delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—making it ideal for harsh environments such as power generation, oil & gas, petrochemical, and heavy manufacturing facilities. Its advanced eddy-current technology enables reliable measurement of shaft runout, bearing housing vibration, axial position, and differential expansion with sub-micron resolution.

Featuring a robust stainless-steel probe body and integrated coaxial cable assembly, the 330881-28-00-150-03-02 is rated for operation across an extended temperature range (–30 °C to +120 °C ambient), with IP67 ingress protection ensuring resilience against dust, moisture, and mechanical stress. The transducer’s optimized frequency response (0–10 kHz typical) supports both low-frequency shaft orbit analysis and high-frequency bearing fault detection. Its factory-calibrated output (−2 VDC to −18 VDC linear voltage proportional to gap) ensures seamless compatibility with Bently Nevada’s industry-standard monitoring systems—reducing commissioning time and minimizing configuration errors during plant upgrades or retrofits.

Key Features

• High-Accuracy Eddy-Current Sensing: Delivers ±0.5% full-scale linearity and repeatability over its operational life, critical for predictive maintenance and asset health monitoring.
• Ruggedized Industrial Design: Stainless-steel probe, high-temp coaxial cable (up to 120 °C), and IP67-rated connector ensure long-term reliability in extreme thermal, vibrational, and corrosive conditions.
• Plug-and-Play Integration: Fully compatible with Bently Nevada 3500/40M monitors and System 1™ software—supports automatic sensor recognition and calibration data transfer via TEDS (Transducer Electronic Data Sheet).
• Extended Diagnostic Capabilities: Enables simultaneous monitoring of multiple machine parameters—including shaft position, vibration, and thrust bearing wear—supporting comprehensive machinery protection strategies.
