Product Introduction
The Bently Nevada 330101-00-31-15-02-05 3300 XL Proximity Probe is a high-precision displacement sensor designed for non-contact monitoring of shaft vibration and position in critical rotating machinery. Part of the 3300 XL series, this 8 mm probe features an extended length of 1.5 meters, providing flexibility for deep or hard-to-reach installation points in turbines, compressors, generators, and large industrial motors.
Engineered for accurate probe-to-target measurement over long distances, this probe ensures consistent signal fidelity and reliable gap measurement even under high-vibration and harsh industrial conditions. It is widely used in machinery protection systems and condition monitoring applications, offering seamless integration with Bently Nevada 3300 XL Proximitor modules.

FAQ
1. Can this probe measure axial and radial vibration simultaneously?
Yes, when properly installed in a Bently Nevada 3300 XL monitoring system, it can support comprehensive displacement measurements.
2. Is the 1.5 m probe suitable for deep or confined machine spaces?
Yes, its extended length is designed for deep installations where standard probes cannot reach.
3. How does probe diameter influence performance?
The 8 mm diameter provides sufficient rigidity to maintain a stable gap and minimize mechanical resonance.
4. What are the environmental limits for this probe?
The probe is suitable for vibration, contamination, and temperature ranges from -40°C to +120°C typical industrial conditions.
5. Is this probe compatible with standard 3300 series modules?
Yes, it is fully compatible with 3300 XL Proximitor and monitoring systems.
6. Does long probe length affect signal fidelity?
The 3300 XL design maintains signal accuracy over the extended length by minimizing mechanical flex and resonance.
7. Can this probe be used in retrofit projects?
Yes, its flexible mounting and extended length make it ideal for retrofits in existing installations.
8. Is calibration required after installation?
Initial verification is recommended, but proper mechanical alignment maintains the probe within its calibrated operating range.
9. How does the probe perform in high-vibration environments?
Its rigid construction and XL series design minimize mechanical movement and signal distortion caused by vibration.
10. What materials are used to ensure long-term durability?
The probe is made from stainless steel and high-strength industrial alloys for resistance to mechanical stress and corrosion.
