Key parameters for the 330102-24-48-05-01-RU are listed below for quick reference:
| Feature | Specification |
|---|---|
| Product Type | 3300 XL 8 mm Proximity Probe |
| Unthreaded Length Option | 2.4 in |
| Overall Case Length Option | 4.8 in |
| Total Length Option | 0.5 meter (1.6 feet) |
| Connector and Cable-Type Option | Miniature coaxial ClickLoc connector with connector protector, standard cable |
| Agency Approval Option | Country Specific Approval |
| Probe Tip Material | Polyphenylene sulfide (PPS) |
| Probe Case Material | AISI 303 or 304 stainless steel (SST) |
| Nominal Probe DC Resistance (0.5 m) | 7.45 ± 0.50 Ω |
| Linear Range | 2 mm (80 mils), from 0.25 to 2.3 mm (10 to 90 mils) |
| Recommended Gap Setting for Radial Vibration | -9 Vdc [approximately 1.27 mm (50 mils)] |
| Probe Temperature Range (Standard) | -52°C to +177°C (-62°F to +350°F) |
Industry Applications
The PPS tip withstands high temperatures up to +177°C, making it suitable for applications near hot bearing housings. Its 2 mm linear range provides ample coverage for most shaft displacement measurements, reducing the risk of sensor saturation during transient events.
Installation and Setup Guidance
Mount the probe using the 3/8-24 UNF thread with a maximum thread engagement of 0.563 in. Ensure the target surface is clean and within the recommended gap of -9 Vdc (approximately 1.27 mm). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable. The maximum field wiring length between the probe and monitor is 305 meters (1,000 feet). Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.
Maintenance and Reliability
Inspect the probe cable and connector periodically for signs of wear or corrosion. The stainless steel case and PPS tip offer resistance to moisture and many industrial chemicals. Relative humidity testing shows less than a 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3, confirming long-term stability in humid environments.
Solving Vibration Monitoring Challenges in Rotating Machinery
The Bently Nevada 330102-24-48-05-01-RU 3300 XL 8 mm Proximity Probe is designed for exactly this scenario. Its robust construction and precise linear range provide reliable gap measurements, enabling early detection of shaft misalignment or bearing wear before unplanned downtime occurs.
Compatibility and Integration
The 330102-24-48-05-01-RU is part of the 3300 XL family and works with Bently Nevada Proximitor sensors and monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga requirements. For non-incendive installations, use drawing 140979 for Class I, Zone 2 compliance.
Selection Guide and Purchasing Advice
When selecting a proximity probe, verify the cable length, thread size, and agency approval match your site requirements. The 330102-24-48-05-01-RU offers a 0.5 m cable with a ClickLoc connector for quick installation. AutoDCSTech stocks this model and can assist with lifecycle status and availability.
