Bently Nevada 330101-01-29-10-01-00 3300 XL 8 mm Probe, 3/8-24 UNF Thread, Without Armor

Product Overview

The Bently Nevada 330101-01-29-10-01-00 is a 3300 XL 8 mm probe featuring a 3/8-24 UNF thread design without armor. This probe is engineered for precise vibration measurement in rotating machinery, addressing the critical need for early fault detection and machine protection. With a robust construction and patented technologies, it delivers reliable performance in demanding industrial environments.

Technical Specifications Breakdown

Key parameters for the 330101-01-29-10-01-00 are listed below for quick reference:

Industry Applications

The 2 mm linear range and high sensitivity (7.87 V/mm) enable accurate detection of rotor dynamic changes, helping prevent catastrophic failures. In chemical plants, the PPS tip and stainless steel case resist corrosion, while the -52°C to +177°C operating range suits both cold and hot process areas.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread into a suitable mounting hole. Ensure the target surface is clean and within the specified gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Use the miniature coaxial ClickLoc connector for secure, quick cable attachment. For field wiring, employ 3-conductor shielded triad cable with tinned wiring; maximum length between the Proximitor Sensor and monitor is 305 meters (1,000 feet).

Maintenance & Reliability

The patented TipLoc and CableLoc designs provide enhanced mechanical strength, with the cable offering 330 N (75 lbf) pull strength. Inspect the probe and cable periodically for physical damage, especially in high-vibration areas. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The Viton O-ring seals differential pressure; contact the custom design department if pressure testing is required.

Compatibility & Integration

This 3300 XL probe works with Bently Nevada extension cables and Proximitor sensors to form a complete measurement system. The standard 1.0 meter system provides 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, a 9 meter system is available with slightly wider tolerance (± 6.5%).

Selection Guide & Purchasing Advice

When selecting a probe, consider the required cable length, environmental temperature, and mounting thread. The 330101-01-29-10-01-00 offers a 1.0 meter cable and standard temperature range, making it suitable for many general-purpose applications. For extreme temperatures, choose the extended temperature range option. AutoDCSTech stocks this model and can advise on compatible extension cables and Proximitor sensors to ensure system integrity.

Troubleshooting & Common Issues

If the probe output is erratic, check the cable connections for looseness or damage. Verify that the target gap is within the recommended -9 Vdc setting. If the signal is noisy, ensure field wiring does not exceed 305 meters and that shielded cable is properly grounded. For drift issues, confirm the probe is within its operating temperature range and not exposed to condensation or corrosive agents.
