4. Product Introduction
The Bently Nevada 330800-16-00-00-01-02 is a PROXPAC XL Proximity Transducer Assembly built around a 3300 XL 8 mm probe. It provides a complete, factory-integrated solution for measuring shaft vibration, position, and speed in rotating machinery.
The rugged PPS housing protects the probe in demanding environments while simplifying field installation. Use this assembly with standard 3300 XL Proximitor Sensors for reliable data in compressors, turbines, and other critical equipment. Proper installation gap and target material are essential for accurate performance.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Flatline output | No power to Proximitor | ✅ High | Measure supply voltage | Verify -24 VDC supply and cabling |
| Wrong gap voltage | Installation gap off | ✅ High | Read DC output voltage | Adjust probe to 8-12 VDC nominal |
| Signal noise | Poor target or EMI | ✅ Medium | Inspect shaft surface runout | Clean target area; check shielding |
| Reduced sensitivity | Probe tip damage | ✅ Medium | Compare scale factor to spec | Replace transducer assembly |
| Mechanical resonance | Long unsupported sleeve | ✅ Low | Check for vibration at housing | Add sleeve support if penetration >12 in |

6. Frequently Asked Questions (FAQ)
What systems is the 330800 compatible with? It works with 3300 XL Proximitor Sensors in both 3300 and 3500 monitoring racks.
How do I determine the correct probe penetration length? Measure the required depth from the mounting surface to the target. Use the part number suffixes for standoff and penetration options.
Is the PPS housing better than metal? Yes for many applications — it offers excellent corrosion resistance, lower weight, and reduced thermal conduction issues.
Do I need an extension cable? Depends on total distance to the Proximitor. The assembly typically includes a short integral cable; order extension as needed.
What target material gives best performance? AISI 4140 steel is standard. Performance varies with other materials — consult the datasheet for scale factor adjustments.
Can this replace older 31000/32000 series housings? Yes. The PROXPAC XL is the modern evolution with improved materials and design.
What warranty applies? 1-year warranty. New original stock with traceability. Installation tips and compatibility checks available.
