Bently Nevada 330907-05-30-05-02-CN 3300 NSv Reverse Mount Probe

Product Introduction

The Bently Nevada 330907-05-30-05-02-CN 3300 NSv Reverse Mount Probe is a high-precision, non-contact eddy-current sensor designed for reverse mounting applications in critical rotating machinery. Part of the 3300 NSv (Narrow Side-view) series, this probe enables accurate shaft vibration and displacement monitoring where standard probe orientation is not feasible due to space or design constraints. Built with robust stainless-steel construction and integrated EMI shielding, it ensures reliable and stable performance in harsh industrial environments. This makes it an essential component for predictive maintenance, machine protection, and early fault detection in turbines, compressors, generators, and other rotating machinery.

Product Specifications

Applications

• Steam and Gas Turbines: Measures shaft vibration and displacement in areas unsuitable for standard probe orientation.

• Compressors: Monitors bearing wear, surge conditions, and cavitation-related vibrations in reverse-mount configurations.

• Electric Motors and Generators: Provides precise rotor displacement and vibration monitoring in confined installation spaces.

• Gearboxes: Detects misalignment, mechanical looseness, and gear mesh issues where conventional mounting is impractical.

• Industrial Pumps: Monitors hydraulic instabilities and shaft deflection in reverse-mount locations.

• Fans and Blowers: Detects imbalance and bearing degradation in areas with space constraints or unconventional mounting.

Advantages

• Reverse Mount Design: Optimized for constrained or unconventional mounting requirements.

• High Accuracy: Maintains excellent linearity and sensitivity for precise shaft vibration and displacement measurements.

• Compact and Robust: Slim 5 mm tip allows installation in tight spaces; stainless-steel construction ensures long-term durability.

• Wide Temperature Range: Operates effectively from −35 °C to +177 °C.

• Integrated EMI Protection: Maintains signal integrity in high electromagnetic interference environments.

• Seamless Integration: Fully compatible with Bently Nevada 3300 XL Proximitor sensors and monitoring systems.

• Low Maintenance: Non-contact sensing reduces wear, minimizing downtime and service requirements.

FAQ

1. How is the 330907-05-30-05-02-CN probe calibrated for accurate displacement measurement?
   Factory-calibrated using an AISI 4140 steel target to ensure linearity and sensitivity.

2. Can this reverse mount probe interface with standard Bently Nevada Proximitor drivers?
   Yes, it works seamlessly with the 3300 XL Proximitor and approved NSv extension cables.

3. What is the maximum vibration frequency measurable by this probe?
   It accurately measures vibration signals up to 10 kHz within its linear range.

4. What type of output signal does the probe provide?
   The output is a voltage proportional to shaft displacement, typically 0–20 V peak-to-peak.

5. Is additional electromagnetic shielding required in high-noise areas?
   No. Integrated EMI shielding ensures reliable performance without external shielding.

6. Can this probe be used in pressurized or oil-submerged environments?
   Yes, rated up to 500 psi and suitable for submerged or pressurized applications.

7. How does the probe maintain measurement accuracy under temperature variations?
   Stainless-steel construction and internal thermal compensation preserve precise measurements across the operating range.

8. Is the probe capable of monitoring both radial and axial displacement?
   Yes, installation orientation determines whether radial or axial vibration is monitored.

9. What signal conditioning equipment is recommended for optimal operation?
   A Bently Nevada 3300 XL Proximitor or equivalent driver provides the necessary power and signal processing.

10. Does extension cable length affect calibration or sensitivity?
    Yes. Each probe is calibrated for a specific cable length, so using the correct matching extension cable is essential.
