Bently Nevada 330901-22-40-10-01-CN 3300 NSv Proximity Probes

Product Introduction

The Bently Nevada 330901-22-40-10-01-CN 3300 NSv Proximity Probe is a precision, non-contact sensor specifically designed for small-shaft, high-speed rotating machinery requiring accurate vibration and radial displacement monitoring. As part of the 3300 NSv (Narrow Side-view) series, this probe provides continuous real-time measurements of shaft vibration and dynamic motion. Its rugged stainless-steel construction and advanced eddy-current sensing technology allow reliable performance in harsh industrial environments, including power generation, petrochemical facilities, and high-speed compressors. The 330901-22-40-10-01-CN probe integrates seamlessly with Bently Nevada 3300 and 3500 monitoring systems, enabling accurate predictive maintenance and early detection of potential machinery faults.

Product Specifications

Applications

The 330901-22-40-10-01-CN probe is ideal for high-speed, space-constrained machinery monitoring, including:

• Small steam, gas, and hydro turbines

• Wide Temperature Range – Operates stably 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 reduces mechanical wear and operational downtime.

FAQ

1. What sensing principle does the 330901-22-40-10-01-CN probe use?
   It employs eddy-current non-contact displacement sensing for accurate vibration and shaft position monitoring.

2. How is this probe connected to a Bently Nevada monitoring system?
   Via a proximitor driver, preserving factory calibration for precise readings.

3. Can the probe be mounted in any orientation?
   Yes, horizontal, vertical, or angled installation is supported, provided the recommended shaft-to-probe 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 hazardous or intrinsically safe locations?
   Yes, when used with certified intrinsically safe barriers or protective housings.

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

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

8. How does temperature variation affect measurement accuracy?
   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 3300/3500 monitoring systems.

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