Bently Nevada 330905-00-13-10-12-CN 3300 NSv Proximity Probes

Product Introduction

The Bently Nevada 330905-00-13-10-12-CN 3300 NSv Proximity Probe is a high-precision, non-contact sensor designed for vibration and shaft displacement monitoring in critical rotating machinery. Part of the 3300 NSv (Narrow Side View) series, this probe provides accurate measurement in applications where space is limited while maintaining long-term reliability. Using advanced eddy-current technology, it delivers real-time detection of shaft movement and vibration, enabling early fault detection, predictive maintenance, and operational safety. Its rugged stainless-steel housing with hermetic sealing ensures stable performance under extreme industrial conditions, making it suitable for turbines, compressors, pumps, motors, and other heavy-duty rotating equipment.

Technical Specifications

Applications

The 330905-00-13-10-12-CN probe is widely used in industries requiring precise shaft vibration and displacement monitoring for high-value rotating equipment:

• Gas and Steam Turbines – Monitors axial displacement and shaft vibration to prevent imbalance and misalignment.

• Compressors and Pumps – Detects bearing wear, mechanical looseness, and cavitation at early stages.

• Motors and Generators – Provides accurate rotor dynamics measurements for predictive maintenance programs.

• Gearboxes and Industrial Fans – Monitors gear mesh irregularities and vibration to ensure reliable operation.

• OEM Machinery – Compact design allows integration into restricted-space machinery.

Advantages

• High Measurement Accuracy – Advanced eddy-current sensing provides precise and stable readings.

• Compact NSv Design – Narrow Side View construction allows installation in tight or confined spaces.

• Durable Construction – Stainless steel housing with hermetic sealing protects against dust, moisture, and corrosive environments.

• Seamless System Integration – Fully compatible with Bently Nevada 3300 series monitoring systems for easy setup and calibration.

• Wide Operating Temperature – Reliable performance from –35 °C to +177 °C in harsh conditions.

• Low Maintenance – Non-contact operation eliminates mechanical wear, reducing downtime.

FAQ

1. Which target material ensures optimal calibration accuracy?
   Factory calibration is performed for AISI 4140 steel; other ferromagnetic materials may require system recalibration.

2. What is the maximum cable extension supported?
   Extensions up to 9 meters are supported when used with a compatible Bently Nevada proximitor.

3. Can this probe be installed in hazardous environments?
   Yes, it meets ATEX and CE Zone 1 requirements with certified accessories.

4. How does temperature variation affect measurement accuracy?
   Integrated temperature compensation minimizes drift across the operating range.

5. What is the typical output sensitivity when connected to a proximitor?
   200 mV per mil (7.87 V/mm) with ±5% tolerance.

6. Does the probe provide both dynamic vibration and static shaft position measurements?
   Yes, it delivers simultaneous vibration and displacement signals.

7. What is the recommended minimum bend radius during installation?
   A minimum bend radius of 25 mm is recommended to protect the cable.

8. Is periodic recalibration required?
   Recalibration is generally only necessary after system reconfiguration or component replacement.

9. Is the probe resistant to electromagnetic interference (EMI)?
   Yes, coaxial cable and internal shielding provide excellent EMI resistance.

10. Is it compatible with older Bently Nevada monitoring systems?
    Yes, when used with the correct proximitor and following proper calibration procedures.
