Technical Specifications Breakdown

Key parameters for the 330101-29-52-05-02-05 are listed below for quick reference:

Industry Applications for the 3300 XL Probe

The 2 mm linear range and high sensitivity (7.87 V/mm) allow precise detection of shaft displacement. With CSA, ATEX, and IECEx approvals, it suits hazardous area installations. The robust stainless steel case and PPS tip withstand physical abuse and chemical exposure common in oil and gas, power generation, and petrochemical plants.

Installation and Setup Guidance

When installing the 330101-29-52-05-02-05, ensure proper gap setting for radial vibration: -9 Vdc (approximately 1.27 mm or 50 mils). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. Maximum field wiring length between the proximitor sensor and monitor is 305 meters (1,000 feet). The miniature coaxial ClickLoc connector simplifies cable attachment, but avoid bending the cable near the connector to prevent damage.

Maintenance and Reliability

Inspect the probe and cable periodically for signs of wear, especially at the tip and connector. The probe operates reliably in temperatures from -52°C to +177°C. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The FluidLoc cable option (if ordered) prevents oil leakage through the cable interior. For extended temperature range applications, the probe tip can withstand up to +218°C.

Reliable Vibration Monitoring with the Bently Nevada 3300 XL 8 mm Probe

For maintenance engineers seeking robust and accurate vibration measurement, the Bently Nevada 330101-29-52-05-02-05 offers a proven solution. This 3300 XL 8 mm probe is designed for eddy-current displacement sensing in critical rotating machinery. Its unthreaded length of 2.9 inches and overall case length of 5.2 inches provide flexibility in mounting configurations. The 0.5 meter (1.6 feet) cable with a miniature coaxial ClickLoc connector ensures secure signal transmission.

Enhanced Durability for Harsh Environments

The 330101-29-52-05-02-05 incorporates patented TipLoc and CableLoc technologies. TipLoc creates a robust bond between the probe tip and body, while CableLoc delivers 330 N (75 lbf) pull strength to secure the cable assembly. The probe tip is molded from polyphenylene sulfide (PPS) plastic, providing thicker encapsulation for improved ruggedness. The case is made from AISI 303 or 304 stainless steel, offering corrosion resistance in demanding industrial settings.

Compatibility and Integration

The 3300 XL 8 mm probe is designed to work with Bently Nevada 3300 XL extension cables and proximitor sensors. The standard 0.5 meter system offers an incremental scale factor of 7.87 V/mm ± 5% over the 80 mil linear range from 0°C to +45°C. For longer cable runs, the 9 meter system provides ±6.5% interchangeability error. The probe's nominal DC resistance is 7.45 ± 0.50 ohms for the 0.5 meter length.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread type (3/8-24 UNF), overall length, and cable connector. The 330101-29-52-05-02-05 is a standard configuration without armor. For applications requiring additional cable protection, consider armored options. Contact AutoDCSTech to confirm current lifecycle status and availability before ordering.
