3300 XL 8 mm Probe – rugged by design

• Bently Nevada engineered the 3300 XL Proximity Probes with a thicker PPS tip encapsulation. This construction withstands severe physical abuse in industrial environments.
• The patented TipLoc molding creates a robust bond between probe tip and body. CableLoc technology provides 330 N (75 lbf) pull strength for secure cable retention.
• You can specify the optional FluidLoc cable to prevent oil leakage through the interior. This feature maintains machine integrity in lubricated environments.
• AISI 303 or 304 stainless steel case offers superior corrosion resistance. The probe operates from -52°C to +218°C with extended temperature range options.

• Environmental resistance: Less than 3% ASF change after 56 days at 93% humidity per IEC 68-2-3. Viton O-ring pressure seal.

Mounting and wiring guidelines

• Use 3-conductor shielded triad cable (16 to 24 AWG) for field wiring. Maximum lead length: 305 meters (1000 feet) to the 3300 XL Proximitor Sensor.
• Maintain the recommended –9 Vdc gap setting for radial vibration monitoring. This equals approximately 1.27 mm (50 mils).
• The 3/8-24 UNF thread allows easy installation in standard mounting holes. You do not need special tools.
• Avoid temperatures below –34°C (–30°F) during operation to preserve the pressure seal integrity.

Frequently asked questions

• Q: Can I use this probe with a 9 m extension cable? Yes, the system works with 9 m cables, but ISF accuracy becomes ±6.5% and DSL < ±0.038 mm.
• Q: Does the probe withstand high pressure? The Viton O-ring seals differential pressure. Contact our custom department if you need tested pressure seals.
• Q: What is the maximum field wiring distance? You can run up to 305 m (1000 feet) between the Proximitor and monitor. Check frequency response graphs for signal roll-off at longer lengths.
• Q: Is the probe tip replaceable? No, the tip is permanently molded using TipLoc technology. The entire probe is a single assembly.
