Description

Technical Overview

The Bently Nevada 3300 XL 11 mm Proximity Probe (Model: 330704-000-050-90-02-05) is a high-precision, non-contact displacement sensor engineered for mission-critical machinery protection and condition monitoring in demanding industrial environments. As part of the trusted 3300 XL series, this probe delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—making it ideal for use with gas turbines, steam turbines, compressors, motors, and other rotating equipment where reliability and accuracy are non-negotiable.

Designed to operate seamlessly with the 3300 XL 25 mm and 50 mm extension cables and 3300 XL monitoring systems, this 11 mm diameter probe features an advanced ceramic-coated stainless steel housing and optimized coil geometry for consistent sensitivity across its calibrated range (typically ±2.0 mm). Its robust construction meets IP67 ingress protection standards, ensuring dependable performance in high-vibration, high-humidity, and oil-contaminated settings common in power generation, petrochemical, and marine applications. The probe’s integrated temperature compensation and low-drift electronics minimize measurement drift over time—reducing false alarms and extending calibration intervals.

Key Features

• High-Accuracy Displacement Sensing: Delivers ±0.5% full-scale linearity and repeatability within ±0.25% across operating temperatures from –30°C to +120°C.
• Rugged Industrial Design: Hermetically sealed ceramic-coated probe tip and corrosion-resistant 316 stainless steel body withstand harsh mechanical and chemical exposure.
• EMI/RFI Immunity: Compliant with IEC 61000-4-3 and IEC 61000-4-6 standards, ensuring stable operation near VFDs, switchgear, and high-power transmission lines.
• Plug-and-Play Compatibility: Fully interoperable with 3300 XL preamplifiers (e.g., 3300 XL 50 mV/mm or 200 mV/mm variants) and legacy 3300 system infrastructure.
• Optimized for Critical Monitoring: Supports API 670-compliant vibration, axial position, differential expansion, and shaft eccentricity measurements.
