Product Overview
The BENTLY 330103-00-03-05-02-05 is an 8mm eddy-current proximity probe from Bently Nevada’s 3300 XL series, designed for high-precision vibration and displacement monitoring in industrial rotating machinery. As a core component of machinery health management systems, it detects radial vibration, axial displacement, and keyphasor signals by generating oscillating electromagnetic fields that interact with conductive surfaces. The resulting eddy currents are converted into standardized voltage outputs (-1 to -17 Vdc), enabling real-time fault detection in critical equipment like turbines and compressors. Engineered for harsh environments, this probe features a stainless steel housing with IP66/NEMA 4X-rated sealing, ensuring resistance to moisture, dust, and chemical exposure. Its plug-and-play design allows full interchangeability with 3300 XL extension cables and proximitor modules without recalibration, reducing maintenance complexity and downtime. Compliant with API 670 4th Edition standards, it seamlessly integrates with control systems (e.g., Bently’s 3500 series monitors) to support predictive maintenance strategies.

Key Features and Benefits
Precision and Interchangeability: The BENTLY 330103-00-03-05-02-05 delivers ±1% accuracy across its 2mm linear range, critical for detecting micro-scale mechanical anomalies like bearing wear or shaft misalignment. Its components (probes, cables, proximitors) are fully interchangeable within the 3300 XL series, eliminating bench calibration and expediting replacements.
Robust Construction: The stainless steel body and corrosion-resistant ClickLoc® connectors withstand high-pressure washdowns, oil immersion, and EMI interference. The IP66 rating ensures reliability in offshore platforms, refineries, and high-humidity settings.
Ease of Installation: Finger-tightened connectors (“click” mechanism) simplify mounting, while M10×1 threading adapts to standard industrial fixtures. Integrated locknuts prevent loosening under vibration, reducing mechanical failure risks.
Diagnostic Compatibility: Outputs dynamic vibration and gap voltage signals for real-time diagnostics via 3500/40M or 3500/42M monitor modules, enabling early alerts for imbalance or rubbing conditions.
Application Areas
The BENTLY 330103-00-03-05-02-05 is deployed in high-risk industrial sectors:
- Power Generation: Monitors steam/gas turbine shaft vibrations and rotor imbalances to prevent blade failures. Detects hydroelectric generator oscillations under low-frequency loads (0.5–10 kHz).
- Oil & Gas: Safeguards centrifugal compressors in pipelines by identifying bearing degradation or seal leaks. High-temperature tolerance (85°C) suits gas turbine exhaust zones.
- Heavy Manufacturing: Tracks gearbox vibrations in steel mills and paper machine rollers, enabling maintenance scheduling during production pauses.
- Aerospace Testing: Validates engine rotor dynamics in test rigs, leveraging 10 kHz frequency response for high-RPM validation.

Installation and Maintenance
Installation Preparation: Mount the probe perpendicular to the target surface (e.g., shaft) with a 1.5–2mm gap for steel. Use shielded triaxial cables (≤305m) to minimize EMI. Match probe-cable lengths (e.g., 5m probe with 5m extension) to prevent signal drift.
Maintenance Recommendations: Bi-annually inspect probe resistance (target: 7–8Ω) and connector integrity. Clean oil/grease buildup with non-abrasive solvents. Verify linearity using TK-3E calibration tools; replace if output deviation exceeds ±5%.
Product Assurance
The BENTLY 330103-00-03-05-02-05 includes a 12-month warranty covering manufacturing defects. Global technical support covers installation guidance and field diagnostics. Units undergo ISO 9001-certified testing, with lifetime firmware updates for compatible monitoring systems.
