Description

Technical Overview

The Bently Nevada 3300 XL 11 mm Proximity Probe (Model: 330703-000-050-10-12-00) is a high-precision, ruggedized sensing solution engineered for continuous vibration and position monitoring in critical rotating machinery applications. As part of the industry-standard 3300 XL family, this probe delivers exceptional linearity, thermal stability, and immunity to electromagnetic interference—making it ideal for use in gas turbines, steam turbines, compressors, motors, and pumps across power generation, oil & gas, and industrial manufacturing facilities.

Designed to operate seamlessly with the 3300 XL 25 mm and 50 mm extension cables and compatible 3300 XL 8 mm or 11 mm proximity transducers, this 11 mm diameter probe features a stainless steel housing and high-temperature epoxy encapsulation for reliable performance in harsh environments—including extreme temperatures, high humidity, and exposure to oils and process chemicals. Its optimized tip geometry ensures consistent sensitivity and repeatable gap measurements from 0.25 mm to 2.5 mm, supporting precise shaft displacement analysis essential for predictive maintenance and machinery protection systems (MPS).

Key Features

• High-Accuracy Sensing: ±1% linearity over full range with temperature-compensated output for stable measurements across operating conditions (−30°C to +120°C ambient)
• Robust Industrial Construction: 316 stainless steel probe body and ceramic-coated tip resistant to corrosion, abrasion, and mechanical impact
• Plug-and-Play Integration: Fully compatible with Bently Nevada 3300 XL monitoring systems, including 3500/40M, 3500/22M, and System 1™ platforms
• EMI-Robust Design: Meets IEC 61000-4-3 (Radiated Immunity) and IEC 61000-4-6 (Conducted Immunity) standards for operation in electrically noisy plant environments
• Long-Term Stability: Minimal drift (<0.1% FS/year) ensures calibration integrity and reduces maintenance frequency
