Bently Nevada 330101-00-55-05-02-05 3300 XL 8 mm Probe without Armor

Competitive Cost-Benefit Analysis for Vibration Monitoring

When selecting proximity probes for rotating machinery, the Bently Nevada 330101-00-55-05-02-05 offers a compelling balance of rugged design and proven performance. This 3300 XL 8 mm probe, with 3/8-24 UNF thread and without armor, is engineered to reduce total cost of ownership through enhanced durability and simplified installation.

Product Overview

The 330101-00-55-05-02-05 is part of the 3300 XL series, a trusted standard in industrial vibration monitoring. It features a patented TipLoc molding method that creates a robust bond between the probe tip and body, minimizing failure risk. The CableLoc design provides 330 N (75 lbf) pull strength, securely attaching the cable and tip to reduce maintenance downtime. This probe is made in the U.S.A. and carries CSA, ATEX, and IECEx approvals, ensuring compliance for hazardous environments.

Technical Specifications Breakdown

Key parameters for the 330101-00-55-05-02-05 are listed below for quick reference:

Industry Applications

The 8 mm diameter provides a thicker PPS encapsulation, offering greater physical robustness compared to smaller probes. This reduces the likelihood of damage during installation or operation, lowering replacement costs. The optional FluidLoc cable prevents oil leakage, a common issue in lubrication systems, further cutting maintenance expenses.

Installation & Setup Guidance

For optimal performance, mount the probe with the recommended gap setting of -9 Vdc, approximately 1.27 mm (50 mils) from the target. 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 3300 XL Proximitor Sensor and monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and free of debris before installation.

Maintenance & Reliability

The probe operates reliably in temperatures from -52°C to +177°C (-62°F to +350°F) for standard versions. The stainless steel case resists corrosion, and the PPS tip withstands harsh environments. Inspect the probe and cable periodically for physical damage, especially at the connector. The Viton O-ring seals differential pressure; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent pressure seal failure.

Selection Guide & Purchasing Advice

When selecting a probe, consider the total length and connector type. The 330101-00-55-05-02-05 includes a 0.5 meter cable with miniature coaxial ClickLoc connector, simplifying field replacement. For applications requiring extended temperature range up to +218°C (+425°F) for the tip, specify the ETR option. Contact AutoDCSTech to verify current lifecycle status and availability before ordering. Our team can help match this probe to your existing Bently Nevada monitoring system.

Troubleshooting & Common Issues

If output signal is erratic, check the field wiring connections and ensure the shield is properly grounded. Verify the probe gap using the -9 Vdc reference. If the probe appears damaged, inspect the tip for wear or contamination. For pressure seal concerns, contact our custom design department for testing options. The probe is not pressure tested prior to shipment, so verify seal integrity in critical applications.
