Description

Technical Overview

The Bently Nevada 330103-00-11-50-02-05 is a high-precision, non-contact eddy-current proximity probe engineered for critical machinery condition monitoring in demanding industrial environments. As part of the trusted 3300 XL 8 mm sensor family, this probe delivers exceptional linearity, thermal stability, and long-term repeatability—essential for reliable shaft vibration, axial position, and differential expansion measurements in rotating equipment such as steam turbines, gas compressors, and large electric motors. Its robust 8 mm diameter sensing tip ensures optimal signal-to-noise ratio and immunity to oil film, steam, or particulate interference commonly encountered in harsh process settings.

Designed for seamless integration with Bently Nevada 3300 XL monitoring systems—including the 3300 rack-based and 3500 series platforms—the 330103-00-11-50-02-05 operates with a standardized 7–14 VDC supply and outputs a calibrated -2 to -18 VDC signal proportional to target displacement. The probe’s integral cable (5 m length) features high-shielded, low-noise coaxial construction with a rugged PTFE-insulated conductor and stainless steel braid, ensuring EMI/RFI resistance in electrically noisy plant environments. Its stainless steel housing and hermetically sealed sensing element provide IP67-rated protection against moisture, corrosion, and mechanical impact—supporting extended service life with minimal calibration drift.

Key Features

• Precision 8 mm Eddy-Current Sensing: Optimized for high-resolution measurement of ferromagnetic targets with ±1% linearity over full 2.0 mm range
• Integrated 5-Meter Cable: Factory-terminated, shielded coaxial cable with stainless steel overbraid for superior noise immunity and mechanical durability
• Rugged Industrial Construction: 316 stainless steel probe body, PTFE insulation, and IP67 ingress protection for operation in extreme temperatures (−30°C to +120°C)
• System Compatibility: Fully compliant with Bently Nevada 3300 XL and 3500 monitoring systems—no configuration required upon installation
• Long-Term Stability: Thermally compensated design minimizes output drift (<0.05% FS/°C), reducing recalibration frequency and maintenance costs
