Bently Nevada 330101-00-30-05-02-00 3300 XL 8 mm Probe

Technical Specifications Breakdown

Key parameters for the 330101-00-30-05-02-00 are listed below for quick reference:

Installation and Setup Guidance

Proper installation is critical for accurate measurements. The probe case thread is 3/8-24 with a maximum thread engagement of 0.563 in. For standard forward-mounted probes, the recommended torque is 11.2 N•m (100 in•lbf), with a maximum rated torque of 33.9 N•m (300 in•lbf). For the first three threads, use 7.5 N•m (66 in•lbf) recommended and 22.6 N•m (200 in•lbf) maximum. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the probe and monitor.

Maintenance and Reliability Considerations

The probe operates reliably in extreme conditions. Standard probes handle -52°C to +177°C (-62°F to +350°F), while extended temperature range probes withstand up to +218°C at the tip. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe case is made of AISI 303 or 304 stainless steel, and the tip uses PPS plastic for durability. Regular inspection of cable integrity and connector tightness is recommended.

Robust Vibration Monitoring with the Bently Nevada 330101-00-30-05-02-00

Industrial rotating machinery demands precise and reliable vibration measurement to prevent catastrophic failures. The Bently Nevada 330101-00-30-05-02-00 3300 XL 8 mm probe offers a rugged solution for eddy-current displacement sensing, engineered for harsh environments. This probe features a 3/8-24 UNF thread, a 0.5 meter (1.6 feet) cable, and a miniature coaxial ClickLoc connector, making it suitable for direct installation into bearing housings and machine casings.

Preventing Machinery Failures with Precision Sensing

Its patented TipLoc molding method creates a robust bond between the probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength. This ensures consistent gap settings and reliable data even under mechanical stress. The 2 mm linear range (0.25 to 2.3 mm from target) covers typical radial vibration and thrust position measurements, with a recommended gap setting of -9 Vdc (approximately 1.27 mm).

Compatibility and Integration

This probe is part of the 3300 XL system and works with matching extension cables and Proximitor sensors. The nominal probe DC resistance (RPROBE) is 7.45 ± 0.50 Ω for the 0.5 m length. Extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. The system delivers a standard incremental scale factor of 7.87 V/mm (200 mV/mil) ±5% over the linear range from 0°C to +45°C.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread size, cable length, and connector type. For availability and lifecycle status, contact AutoDCSTech. Our team can help match the exact part to your machine train requirements.

Troubleshooting Common Issues

If readings are erratic, check the cable for damage and ensure the connector is fully seated. Verify the gap voltage is within the recommended -9 Vdc range. If the probe shows signs of physical abuse, replace it immediately. For pressure seal concerns, note that probes are not pressure tested before shipment; contact the custom design department if testing is required.
