Bently Nevada 330101-00-24-10-02-05 Eddy Current Probe

Product Overview

The Bently Nevada 330101-00-24-10-02-05 is a high-performance 3300 XL 8 mm proximity probe designed for critical machinery vibration and position monitoring. Manufactured in the U.S.A., this unarmored sensor features a 3/8-24 UNF thread configuration with a 0.0-inch unthreaded length, a 2.4-inch overall case length, and a 1.0-meter (3.3 feet) total cable length. Equipped with a ClickLoc miniature coaxial connector and certified under hazardous area approvals (CSA, ATEX, IECEx), it offers highly accurate, non-contacting measurements of shaft displacement. This industrial sensor package has a net component weight of approximately 323 g/m (11.4 oz), ensuring a dense, robust build that stands up to severe operational environments.

Key Advantages

• Advanced Structural Integrity: Features a patented TipLoc molding method that creates a highly robust bond between the polyphenylene sulfide (PPS) tip and the stainless steel case, shielding the coil inside.
• High Cable Pull Strength: Utilizes a patented CableLoc design providing up to 330 N (75 lbf) of pull strength, preventing common failures due to physical tugging or cable strain.
• Hazardous Area Certified: Comes standard with option code 05, meeting globally recognized CSA, ATEX, and IECEx safety standards for explosive atmospheres.
• Reliable Compliance: Authentic U.S.A. production infrastructure supports the provision of an official Certificate of Origin (COO) upon ordering request.

Technical Specifications

Field Installation Tips

• Optimal Gap Adjustments: For radial vibration monitoring layouts, the manufacturer recommends targeting a nominal gap voltage configuration of -9 Vdc, which corresponds roughly to a physical gap separation of 1.27 mm (50 mils) from the target face.
• Field Wiring Management: Secure connections using 0.2 to 1.5 mm² (16 to 24 AWG) tinned field wiring. A 3-conductor shielded triad cable is strongly recommended to protect proximity signals across the maximum permissible distance of 305 meters (1,000 feet) to the monitor interface.
• Handling and Strain Control: Keep in mind that despite the durable 323 g/m (11.4 oz) build density of the premium stainless steel shell, exposing the probe seal below -34°C (-30°F) can compromise the integrated Viton® O-ring seal pressure parameters over time.

Frequently Asked Questions

Q1: Are the 3300 XL 8 mm proximity probes factory-tested for pressure sealing?

A1: No, these probes are designed to seal differential pressure between the case and tip using a Viton® O-ring, but they are not pressure tested prior to shipment from the factory. If your process loop requires certified pressure boundary validation, you must request custom design testing prior to placement of the order.

Q2: What benefit does the 8 mm tip structure yield over smaller alternatives?

A2: The 8 mm core profile permits a significantly thicker encapsulation layer of PPS plastic around the inner probe coil. This structural enhancement, combined with a wider matching steel body diameter, ensures increased mechanical robustness and stability against physical impacts.

Q3: How does the FluidLoc option change probe performance if added?

A3: The standard model cable is highly robust. However, modifying a 3300 XL assembly to a FluidLoc specification adds an internal block structure within the cable jacket. This configuration blocks process oils or alternative dynamic machine liquids from wicking out of the machine housing via the cable's internal conductor spacing.
