Description

Technical Overview

The Bently Nevada 330905-00-09-05-02-CN is a high-precision 3300 NSv Proximity Probe engineered for mission-critical machinery protection and condition monitoring in industrial automation and rotating equipment applications. Designed to operate within the industry-standard 3300 XL and 3300 NSv monitoring systems, this probe delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—ensuring reliable displacement and vibration measurements under demanding plant-floor conditions. Its robust construction features a stainless steel housing and PTFE-insulated cable, enabling dependable performance in high-temperature, high-humidity, and chemically aggressive environments common in power generation, oil & gas, petrochemical, and heavy manufacturing facilities.

Calibrated to meet API 670 (4th Edition) requirements for machinery protection systems, the 330905-00-09-05-02-CN provides accurate shaft relative vibration and axial position data with a standard sensitivity of 7.87 V/mm (200 mV/mil) and a linear range optimized for 9 mm target diameters. The probe’s integrated coaxial cable (2 m length, standard) ensures low-noise signal transmission and minimizes grounding issues—critical for maintaining measurement integrity in electrically noisy substations or near large variable frequency drives (VFDs). Its compatibility with Bently Nevada’s NSv-series monitors enables seamless integration into modern asset health management platforms, supporting predictive maintenance strategies and real-time operational decision-making.

Key Features

• High-Accuracy Sensing: Precision-machined tip and factory-calibrated electronics deliver ±1% linearity across the full measurement range.
• Rugged Industrial Design: Stainless steel probe body and chemical-resistant PTFE cable jacket rated for continuous operation up to +120°C ambient temperature.
• EMI/RFI Immunity: Engineered to meet IEC 61000-4-3 and IEC 61000-4-6 standards—ideal for installations near high-power motors, switchgear, and arc furnaces.
