Bently Nevada 330103-01-04-10-02-CN 3300 XL 8mm Proximity-Sonde

Description

The 330103-01-04-10-02-CN functions as an eddy current non-contacting sensor designed to deliver continuous dynamic and static gap measurements inside heavy processing machinery. This specific probe features a 3/8-24 UNF fractional thread body profile engineered to map real-time physical displacement, shaft vibration, and position characteristics when linked into a complete 3300 XL 8mm Proximity Transducer System. The instrument emits a high-frequency RF field from its encapsulated tip, generating an output voltage linearly proportional to the exact distance to a target conductive metal surface. Optimized for integration with standard machinery protection systems like the 3500 series framework, it withstands aggressive environments while delivering high-accuracy data outputs required by operations and plant maintenance personnel.

Features

• Complete component interchangeability across identical configurations without requiring individual bench re-calibration.
• Thick polyphenylene sulfide (PPS) tip encapsulation ensuring premium sealing against chemical contamination and high pressure.
• Gold-plated ClickLoc connectors providing reliable electrical contact and mechanical resistance against industrial vibrations.
• Integrated wire-molded lock nut for robust thread engagement during deep machine housing installations.
• Fully compliant with the American Petroleum Institute (API) 670 Standard for linear range, mechanical profile, and temperature tracking stability.

Applications

• Continuous radial vibration and axial position measurements on fluid-film bearing machinery.
• Oil film thickness evaluation on heavy turbomachinery, compressors, and industrial pumps.
• High-speed Keyphasor reference phase logging and rotational speed counting applications.

Installation Guidelines

• Gap Voltage Alignment: During physical mounting, adjust the mechanical position of the sensor thread until the system bias voltage outputs around -10.0 Vdc, matching the exact midpoint of the system's linear response range.
• Minimum Clearance Margins: Ensure an unobstructed radial space of at least 16 mm around the sensor tip to prevent unintentional cross-talk or target interference from adjacent casing walls.
• Connector Torque Protection: Tighten the miniature coaxial connectors by finger pressure only; avoid using heavy pliers to prevent stripping or snapping the internal gold pins.
• Cable Protection Layer: Feed the integrated flexible lead line directly into a dedicated rigid conduit layer to protect against mechanical shear actions inside the hot fluid-film bearing compartment.

Compliance and Certifications

• Hazardous Area Approvals: CN option meets state standards for intrinsically safe and non-incendive environments when paired with approved Zener barriers or galvanic isolators.
• Mechanical Standard Compliance: Fully meets all geometric envelope requirements outlined under the API 670 Machinery Protection standard guidelines.
