Product Overview

The 330104-03-09-05-02-05 is a metric-threaded, armored proximity sensor from Bently Nevada’s premier 3300 XL series. This 8 mm eddy current probe is engineered for non-contacting displacement measurements, converting the physical gap between the probe tip and a conductive target into a linear voltage signal. As a foundational component of Turbine Supervisory Instrumentation (TSI), it provides high-fidelity data for monitoring radial shaft vibration, axial thrust position, and eccentricity. This specific configuration is designed for rugged industrial applications, featuring a stainless steel armored lead and an M10 x 1 threaded housing to ensure mechanical integrity in the most taxing machinery environments.

Engineering Excellence and Durability

This 3300 XL probe incorporates patented manufacturing technologies to maximize service life and measurement stability:

• TipLoc Molding: An advanced process creates a molecular-level bond between the Polyphenylene Sulfide (PPS) plastic tip and the stainless steel body, preventing delamination and ensuring a vacuum-tight seal against oil and moisture wicking.

• CableLoc Mechanism: A robust internal anchoring system provides 330 N (75 lbf) of cable pull strength, shielding the electrical connection from mechanical strain during installation.

• Stainless Steel Armor: The FEP-insulated coaxial lead is encased in flexible 304 stainless steel armor, providing superior protection against abrasion and accidental cutting within machinery housings.

• Corrosion Resistance: The probe body and armor are constructed from AISI 300 series stainless steel, offering excellent resilience against corrosive industrial fluids and gases.

System Integration and Applications

The 330104-03-09-05-02-05 is a versatile solution for comprehensive machinery health monitoring:

• Machine Protection: Essential for monitoring fluid-film bearing equipment such as steam turbines, centrifugal compressors, and high-speed pumps.

• Total Interchangeability: Probes, extension cables, and Proximitor sensors of the same system length (0.5m) can be swapped without manual bench calibration.

• Backward Compatibility: Electrically and physically compatible with legacy 3300 series 5 mm and 8 mm components when minimum bend radii are observed.

• EMI/RFI Immunity: Optimized circuitry meets European CE mark standards for electromagnetic compatibility, ensuring stable signals in high-interference environments.
