Description

Technical Overview

The Bently Nevada 330104-05-17-10-11-05 is a high-precision, industrial-grade proximity probe engineered as part of the trusted 3300 XL 8 mm sensor family. Manufactured by Baker Hughes (under the Bently Nevada brand), this probe delivers exceptional reliability and accuracy for non-contact displacement, vibration, and position monitoring in critical rotating machinery applications. Designed to operate seamlessly with the 3300 XL 8 mm eddy-current transducer system—including compatible extension cables and proximitor modules—the 330104-05-17-10-11-05 ensures stable, linear output across its calibrated range while maintaining immunity to electromagnetic interference, oil mist, steam, and extreme ambient temperatures. Its robust stainless steel housing, hermetically sealed construction, and optimized coil geometry enable consistent performance in harsh industrial environments—commonly found in power generation, oil & gas, petrochemical, and heavy manufacturing facilities. This probe is supplied in New Surplus Condition, meaning it is unused, factory-fresh, and sourced directly from authorized Baker Hughes distribution channels or certified inventory partners. Each unit undergoes rigorous pre-shipment functional verification and arrives with full traceability documentation. The product carries a standard 24-month limited warranty covering material defects and workmanship, reflecting Bently Nevada’s commitment to long-term operational integrity and customer confidence. Measuring 100 mm in overall length with a probe diameter of 8 mm and a threaded M10 × 1.0 mounting interface, the device weighs just 125 g and is precision-machined in the United States—affirming its Country of Origin: USA. As an essential component of predictive maintenance and condition monitoring strategies, the 330104-05-17-10-11-05 supports ISO 10816 and API 670 compliance, enabling early fault detection for shaft orbit analysis, thrust position verification, differential expansion tracking, and bearing wear assessment.

Detailed Specifications

Key Features

• Precision 8 mm Sensing Technology: Engineered for high-resolution measurement with ±1% linearity error over full range—critical for detecting sub-micron shaft movements during startup, shutdown, and steady-state operation.
• Hermetic Stainless Steel Construction: 316 stainless steel probe body with laser-welded ceramic insulator ensures corrosion resistance in aggressive chemical, saline, and high-humidity environments.
• Integrated Shielded Cable: Pre-terminated 5-conductor cable minimizes noise coupling and eliminates field termination errors—supports reliable signal transmission up to 300 meters when used with proper grounding practices.
• Thermal Stability: Advanced coil winding and compensation techniques deliver drift of less than 0.05% FS/°C—enabling stable gap monitoring even during rapid turbine thermal transients.
• API 670-Compliant Output: Delivers standardized negative DC voltage output (e.g., –2.0 V at 1.0 mm gap) fully compatible with Bently Nevada 3300/3500 monitors, System 1 software, and third-party DCS/PLC interfaces.
• Plug-and-Play Integration: Direct compatibility with 3300 XL Proximitor modules (e.g., 3300 XL 50 mV/mm or 100 mV/mm variants) and all 3300 series extension cables—no recalibration required upon installation.
• Traceable Calibration Certificate: Each probe ships with NIST-traceable calibration data including sensitivity, linearity, frequency response, and thermal coefficient—supporting audit readiness and regulatory compliance.

Applications

• Turbomachinery Monitoring: Real-time shaft vibration, axial position, and radial clearance measurement on steam turbines, gas turbines, and centrifugal compressors per API 612 and API 617 standards.
• Generator & Motor Protection: Detection of rotor eccentricity, bearing wear progression, and stator-to-rotor rub conditions in large synchronous and induction motors operating above 1 MW.
• Pump & Fan Health Assessment: Continuous monitoring of impeller runout, coupling misalignment signatures, and bearing housing deflection in API 610 and API 676 service pumps.
• Power Generation Asset Integrity: Integration into digital twin frameworks and IIoT-enabled predictive maintenance platforms for early warning of imbalance, resonance, and mechanical looseness.
• Oil & Gas Critical Rotating Equipment: Deployment on reciprocating compressors, LNG train drivers, and offshore platform turbogenerators where environmental resilience and SIL-2 functional safety alignment are mandatory.
• Research & Development Test Benches: High-fidelity dynamic testing of prototype bearings, seals, and rotor dynamics under controlled laboratory conditions—leveraging the probe’s wide bandwidth (0–10 kHz) and low phase lag.
