Description

Technical Overview

The Bently Nevada 330525-10 is a high-precision, non-contact proximity sensor engineered for mission-critical machinery protection and condition monitoring in demanding industrial environments. As part of the trusted 3300 XL 25 mm Proximitor® family, this sensor delivers exceptional linearity, stability, and immunity to electromagnetic interference—ensuring reliable shaft displacement, vibration, and position measurements across turbines, compressors, motors, and generators. Its robust design meets stringent API 670 (4th & 5th Edition) standards for machinery protection systems, making it ideal for oil & gas, power generation, petrochemical, and marine applications where uptime and predictive maintenance are paramount.

Utilizing advanced eddy-current technology, the 330525-10 operates with a 25 mm probe diameter optimized for medium-to-large rotating equipment. It interfaces seamlessly with Bently Nevada 3300 XL monitoring systems—including the 3500 series—and supports both DC voltage output (−2 V to −18 V) and dynamic AC output for simultaneous gap and vibration analysis. The sensor’s temperature-compensated electronics maintain accuracy across a wide operating range (−30 °C to +85 °C), while its hermetically sealed, stainless-steel construction ensures long-term reliability in high-vibration, high-humidity, or corrosive atmospheres.

Key Features

• API 670 Compliant: Fully certified for use in machinery protection systems per API RP 670 requirements.
• High Linearity & Repeatability: ±1% full-scale linearity and <0.25% full-scale repeatability ensure precise shaft position and vibration data.
• Rugged Industrial Design: Stainless-steel probe housing with integral 3-meter coaxial cable (RG-174/U) and MIL-C-5015 connector for harsh plant-floor conditions.
• Integrated Temperature Compensation: Maintains measurement integrity across extreme ambient and process temperatures without external calibration.
• Plug-and-Play Compatibility: Direct interoperability with 3300 XL Proximitor monitors and legacy 3300 systems—minimizing integration time and engineering overhead.
