Product Overview

The 330101-00-36-05-02-00 is a high-performance eddy current proximity transducer belonging to the Bently Nevada 3300 XL 8 mm series. This non-contacting displacement sensor is engineered to provide precise measurements of the gap between the probe tip and a conductive target, typically a rotating shaft. As a foundational element of Turbine Supervisory Instrumentation (TSI), it delivers real-time data for radial vibration, axial thrust position, and eccentricity monitoring. This specific model features a 3/8-24 UNF threaded body and a 0.5-meter integrated cable, designed for localized installation on high-speed rotating assets such as steam turbines, centrifugal compressors, and industrial pumps.

Core Engineering Characteristics

The 3300 XL series incorporates proprietary manufacturing advancements that significantly improve field longevity compared to legacy sensors:

• TipLoc Molding: A specialized process that chemically bonds the probe tip to the stainless steel body, creating a vacuum-tight seal that prevents oil or process fluids from wicking into the sensing coil.

• CableLoc Anchoring: An internal cable securing system providing a 330 N (75 lbf) pull strength, protecting the coaxial lead from mechanical stress during installation or maintenance.

• Advanced RFI/EMI Immunity: Engineered to meet European CE mark standards, the probe operates reliably in high-frequency interference environments without the need for specialized shielded conduits.

• Polyphenylene Sulfide (PPS) Tip: The 8 mm tip is encapsulated in high-durability PPS plastic, offering superior chemical resistance and thermal stability across a wide operating range.

System Integration and Applications

This proximity transducer is designed for seamless inclusion in comprehensive machinery protection strategies and is fully compliant with API 670 standards:

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

• Backward Compatibility: Electrically and physically compatible with non-XL 3300 series 5 mm and 8 mm components, facilitating cost-effective facility upgrades.

• Keyphasor Capability: Optimized for providing timing and speed reference signals (Phase Angle) for vibration analysis and RPM tracking.

• Hazardous Area Readiness: Certified for deployment in Zone 0, 1, and 2 environments, ensuring safe operation in oil, gas, and power generation facilities.
