Description

Technical Overview

The Bently Nevada 330704-000-050-10-01-05 is a high-precision 3300 XL 11 mm proximity probe engineered for mission-critical machinery protection and condition monitoring in demanding industrial environments. As part of the industry-leading 3300 XL family, this probe delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—ensuring reliable vibration and position measurements across turbines, compressors, motors, and other rotating equipment. Its robust stainless steel construction and hermetically sealed design meet stringent IP67 and NEMA 4X requirements, enabling dependable operation in high-humidity, dusty, or chemically aggressive settings common in power generation, oil & gas, and heavy manufacturing facilities.

Designed for seamless integration with the 3300 XL 25 mm and 50 mm extension cables and 3300 XL monitor systems, the 330704-000-050-10-01-05 maintains tight calibration traceability to ISO 17025-accredited standards. The probe’s optimized 11 mm diameter sensing face provides an ideal balance between resolution and standoff distance, supporting accurate gap measurement within a linear range of 2.0 mm (0.08 in) and a sensitivity of 4.0 V/mm (100 mV/mil). Its low-noise output and wide operating temperature range (–30 °C to +120 °C) ensure consistent performance under transient thermal loads and extended runtime conditions—minimizing false alarms and maximizing asset uptime.

Key Features

• Precision Calibration: Factory-calibrated to ±0.5% linearity tolerance with individual calibration certificate traceable to national standards
• Robust Construction: 316 stainless steel housing, PTFE-insulated coaxial cable, and epoxy-sealed connector for corrosion resistance and mechanical durability
• EMI/RFI Immunity: Meets IEC 61000-4-3 (10 V/m) and IEC 61000-4-6 (10 V) standards—critical for installations near VFDs, switchgear, and high-power cabling
• Direct System Compatibility: Plug-and-play integration with Bently Nevada 3300 XL monitors, including 3300/16, 3300/20, and 3500 series systems
• Long-Term Stability: Drift <0.1% per year under normal operating conditions—reducing recalibration frequency and lifecycle cost
