Precision Vibration Monitoring with the Bently Nevada 3300 XL 8 mm Probe
For critical rotating machinery, accurate vibration measurement is essential to prevent unplanned downtime and catastrophic failures. The Bently Nevada 330101-23-38-10-02-00 3300 XL 8 mm Probe delivers the ruggedness and reliability required for continuous protection in harsh industrial environments. This non-contact probe is designed for eddy current displacement measurement, providing a linear output proportional to the gap between the probe tip and the target surface.
Technical Specifications Breakdown
Key parameters for the 330101-23-38-10-02-00 are listed below for quick reference:
| Feature | Specification |
|---|---|
| Product Type | 3300 XL 8 mm Probe, 3/8-24 UNF thread, without armor |
| Unthreaded Length Option | 23 = 2.3 in |
| Overall Case Length Option | 38 = 3.8 in |
| Total Length Option | 10 = 1.0 meter (3.3 feet) |
| Connector and Cable-Type Option | 02 = Miniature coaxial ClickLoc connector, standard cable |
| Agency Approval Option | 00 = Not required |
| Probe Tip Material | Polyphenylene sulfide (PPS) |
| Probe Case Material | AISI 303 or 304 stainless steel (SST) |
| Linear Range | 2 mm (80 mils). Linear range begins at approximately 0.25 mm (10 mils) from target and is from 0.25 to 2.3 mm (10 to 90 mils) (approximately –1 to –17 Vdc) |
| Incremental Scale Factor (ISF) Standard 5 or 1 meter System | 7.87 V/mm (200 mV/mil) ± 5% including interchangeability error when measured in increments of 0.25 mm (10 mils) over the 80 mil linear range from 0°C to +45°C (+32°F to +113°F) |
| Probe Temperature Range (Standard) | -52°C to +177°C (-62°F to +350°F) |
Industry Applications for Enhanced Machine Protection
The 2 mm linear range allows precise gap measurement, enabling early detection of shaft misalignment, imbalance, or bearing wear. In refineries and power plants, the robust stainless steel case and PPS tip withstand high temperatures and corrosive atmospheres, ensuring long-term stability.
Installation and Setup Guidance
Proper mounting is critical for accurate readings. Use the 3/8-24 UNF thread to secure the probe into a mounting block or bracket. The recommended gap setting for radial vibration is -9 Vdc [approximately 1.27 mm (50 mils)]. Torque the probe case to the recommended 11.2 N•m (100 in•lbf) for standard forward mounted probes. For the first three threads, use 7.5 N•m (66 in•lbf). Ensure the probe tip is clean and free of debris before installation. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three conductor shielded triad cable. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet).
Maintenance and Reliability Considerations
Inspect the probe cable and connector periodically for signs of wear or damage. The patented CableLoc design provides 330 N (75 lbf) pull strength, but avoid excessive bending or pulling during maintenance. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring. If the application involves high humidity, note that the Average Scale Factor changes less than 3% when tested in 93% humidity per IEC standard 68 2 3 for up to 56 days. For extended temperature range applications, the probe tip can operate up to +218°C (+425°F) and the cable up to +260°C (+500°F).
Selection Guide and Purchasing Advice
When selecting a replacement or spare probe, verify the total length, thread type, and connector option. The 330101-23-38-10-02-00 is a 1.0 meter probe with miniature coaxial ClickLoc connector. For applications requiring a different cable length or connector, consult the full 3300 XL series options.
