Product Overview

The 330101-00-15-10-02-05 is a high-precision eddy current proximity probe from Bently Nevada’s 3300 XL series. This 8 mm sensor is engineered for non-contacting displacement measurements, providing essential data for radial vibration, axial thrust, and shaft position monitoring. By utilizing a high-performance Polyphenylene Sulfide (PPS) plastic tip, the sensor offers superior resistance to chemical erosion and moisture ingress, making it a cornerstone for Turbine Supervisory Instrumentation (TSI) in demanding industrial environments.

Technical Configuration

The specific model number 330101-00-15-10-02-05 indicates the following mechanical and electrical profile:

• Unthreaded Body Length: 0.0 inches (Fully threaded case)

• Overall Case Length: 1.5 inches

• Total System Length: 1.0 Meter (approx. 3.3 feet)

• Connection Interface: Miniature coaxial ClickLoc connector

• Agency Certifications: CSA, ATEX, and IECEx approved for hazardous locations

• Scale Factor: 7.87 V/mm (200 mV/mil)

• Linear Range: 2.0 mm (80 mils)

• Operating Temperature: -51 °C to +177 °C

Patented Durability and Design

To ensure long-term reliability in high-speed rotating machinery, this probe incorporates several proprietary engineering advancements:

• TipLoc Molding: An advanced manufacturing process that creates a molecular-level bond between the probe tip and the stainless steel body, preventing delamination and fluid wicking into the sensing coil.

• CableLoc Mechanism: A patented internal anchoring system providing 330 N (75 lbf) of pull strength, shielding the coaxial lead from mechanical strain during installation or operation.

• Enhanced Coil Protection: The sensing coil is deeply encapsulated within a thicker layer of PPS plastic to withstand physical impact and environmental degradation.

• EMI/RFI Immunity: Optimized circuitry ensures stable measurements in high-interference environments, meeting European CE standards without the use of specialized shielded conduits.

Integration and Applications

The 3300 XL 8 mm system is designed for total interchangeability. Probes, extension cables, and Proximitor sensors of the same system length (1m) can be swapped without the need for manual bench calibration.

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

• Versatile Mounting: Standard 3/8-24 UNF threading allows for seamless installation in both high-density DIN-rail and traditional panel-mount configurations.

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