Description

Technical Overview

The Bently Nevada 330909-00-20-10-02-CN is a high-precision 3300 NSv Proximity Probe engineered for mission-critical machinery protection and condition monitoring in industrial automation environments. Designed to operate within the robust 3300 NSv sensor system architecture, this probe delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—ensuring reliable displacement and vibration measurements across demanding applications such as steam turbines, compressors, motors, and generators. Its advanced eddy-current sensing technology enables non-contact measurement of shaft displacement, runout, and vibration with sub-micron resolution, supporting predictive maintenance strategies and real-time asset health assessment.

Manufactured to stringent API 670 (4th Edition) and ISO 10816 standards, the 330909-00-20-10-02-CN integrates seamlessly with Bently Nevada 3300/3500 series monitors and supports both standard and extended temperature operation (-30°C to +120°C ambient). The probe’s stainless steel housing, PTFE-insulated cable, and hermetically sealed tip ensure long-term reliability in harsh environments—including high humidity, oil immersion, and exposure to aggressive chemicals. Its calibrated output (7.87 V/mm or 200 mV/mil) is optimized for compatibility with industry-standard monitoring systems, minimizing configuration overhead during installation and commissioning.

Key Features

• High-Accuracy Eddy-Current Sensing: Delivers ±1% linearity error over full range with minimal temperature drift (<0.05%/°C).
• Ruggedized Industrial Design: Stainless steel probe body and integral 5-meter PTFE-insulated cable rated for continuous operation up to 120°C.
• System-Ready Integration: Pre-calibrated and compatible with Bently Nevada 3300 NSv extension cables, proximitor modules, and Asset Management Software (AMS).
