Bently Nevada 330851-02-000-050-50-00-05 Proximity Probe

Product Overview

The Bently Nevada 330851-02-000-050-50-00-05 is a high-precision 3300 XL series proximity probe engineered for critical machinery condition monitoring and vibration analysis. Featuring an M30x2 metric thread configuration, this eddy current transducer delivers accurate non-contact measurement of shaft position, radial vibration, and axial displacement on high-speed rotating assets like turbines, compressors, and pumps.

Constructed with a UL94 V-0 certified PEEK tip and a 304 stainless steel housing, the 330851-02-000-050-50-00-05 utilizes a triaxial FluidLoc® cable to prevent fluid leakage along the inner cable core. Weighing 0.23 kg (0.51 lbs) for the base unit (with a 0.33 kg / 0.73 lbs armored variant) and an estimated shipping weight of 0.55 kg (1.21 lbs), this probe carries ATEX/IECEx Ex ia hazardous area approvals and marine compliance for reliable operation in extreme industrial environments.

Core Technical Advantages

• Extreme Thermal Resistance: Validated for 200°C continuous operating temperatures with temporary surge handling up to 250°C.
• FluidLoc® Triaxial Cable Technology: Features 3-layer XTFE insulation with 500V AC withstand to seal against liquid ingress along the cable length.
• Multi-Hazardous & Marine Certifications: Certified for Zone 0 (Ex ia IIC T4), Class I Div 1 environments, and ABS Type 4 marine application standards.
• Robust Electromagnetic Immunity: Fully compliant with EN 61000-6-2/4 and FCC CFR47 standards to ensure signal stability in high-EMI environments.

Technical Specifications

Installation & Handling Guidelines

• Proper Torque Application: Tighten probe housing using a calibrated torque wrench to a maximum installation torque of 68 N·m to prevent body deformation.
• Connector Protection: Maintain clean connector faces and use protective rubber caps until final attachment to the extension cable to prevent signal degradation.
• Cable Routing: Ensure minimum bend radius requirements are met along the 5-meter FluidLoc® cable to avoid mechanical stress on the internal shielding layers.
