Bently Nevada 330901-00-32-05-02-CN 3300 NSv Proximity Probes

Product Introduction

The Bently Nevada 330901-00-32-05-02-CN 3300 NSv Proximity Probe is a high-precision, non-contact sensor engineered for small-shaft, high-speed rotating machinery where accurate monitoring in restricted spaces is critical. Part of the 3300 NSv (Narrow Side-view) series, this probe provides continuous, real-time measurement of shaft vibration and radial displacement. Its rugged stainless-steel housing and advanced eddy-current technology allow reliable operation in harsh industrial environments, including petrochemical plants, power generation facilities, and high-speed compressors. Designed for seamless integration with Bently Nevada 3300 and 3500 monitoring systems, the probe ensures accurate machinery protection, predictive maintenance, and early fault detection.

Product Specifications

Applications

The 330901-00-32-05-02-CN probe is suitable for tight-space installations and high-speed machinery monitoring, including:

• Small steam, gas, and hydro turbines

• High-speed compressors and pumps

• Industrial fans, blowers, and motors with limited clearance

• Rotating equipment in petrochemical and refinery operations requiring precise vibration and displacement data

• Gearboxes and auxiliary equipment integrated with Bently Nevada 3300/3500 monitoring systems

Advantages

• Temperature Stability – Operates reliably from –35 °C to +177 °C with minimal signal drift.

• Seamless System Integration – Fully compatible with Bently Nevada 3300 and 3500 monitoring platforms.

• Low Maintenance – Non-contact measurement eliminates mechanical wear and reduces operational downtime.

FAQ

1. What sensing technology does the 330901-00-32-05-02-CN probe use?
   It uses eddy-current non-contact displacement sensing for precise vibration and position monitoring.

2. How is the probe connected to a Bently Nevada monitoring system?
   Via a proximitor driver, maintaining factory calibration for accurate readings.

3. Can the probe be mounted in any orientation?
   Yes, horizontal, vertical, or angled installation is possible, provided the recommended shaft gap is maintained.

4. What is the recommended probe-to-shaft gap?
   Approximately 1.0 mm ±0.2 mm depending on the target material and system calibration.

5. Is this probe suitable for intrinsically safe or hazardous environments?
   Yes, when used with certified intrinsically safe barriers or protective housings.

6. What is the frequency response range of the probe?
   DC to 10 kHz, suitable for high-speed vibration measurement.

7. Can the probe measure vibration on non-metallic shafts?
   No, eddy-current sensing requires a conductive metallic target.

8. How does temperature variation affect measurement stability?
   Built-in temperature compensation ensures stable output from –35 °C to +177 °C.

9. What type of output signal does the probe provide?
   A proportional voltage signal compatible with Bently Nevada monitoring systems.

10. Does the probe require shielding in high electromagnetic interference environments?
    Yes, proper grounding and cable shielding are recommended to maintain signal integrity.
