Bently Nevada 330906-02-12-10-12-05 3300 NSv Reverse Mount Probe

Product Introduction

The Bently Nevada 330906-02-12-10-12-05 3300 NSv Reverse Mount Probe is a high-precision, non-contact eddy-current sensor designed specifically for reverse mounting applications in critical rotating machinery. Unlike standard NSv probes, this model allows installation in constrained spaces where the probe must be mounted in the opposite direction relative to the shaft. It is part of the 3300 NSv series, recognized for its accuracy, stability, and reliability in vibration and shaft displacement measurement. Engineered for severe industrial environments, the probe ensures consistent performance under extreme temperatures, pressures, and electromagnetic interference, making it ideal for predictive maintenance and machinery protection programs across turbines, compressors, pumps, and motors.

Product Specifications

Applications

• Steam and Gas Turbines: Measures shaft vibration and displacement in locations where conventional probe orientation is not possible.

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

• Electric Motors and Generators: Tracks rotor displacement and vibration in tight or reverse mounting spaces.

• Gearboxes: Detects misalignment, mechanical looseness, and gear mesh issues in compact installations.

• Industrial Pumps: Provides accurate monitoring of hydraulic instabilities and shaft deflection in confined spaces.

• Fans and Blowers: Detects imbalance and bearing degradation where standard probe orientation is infeasible.

Advantages

• Reverse Mount Design: Optimized for applications with limited installation space or unconventional mounting requirements.

• High Accuracy: Excellent linearity and sensitivity provide precise vibration and displacement measurements.

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

• Wide Temperature Range: Reliable performance from −35 °C to +177 °C.

• Integrated EMI Protection: Built-in shielding ensures signal stability in high electromagnetic interference zones.

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

• Low Maintenance: Non-contact sensing minimizes wear, reducing downtime and service requirements.

FAQ

1. How is the 330906-02-12-10-12-05 probe calibrated for accurate displacement measurements?
   Each probe is factory-calibrated using an AISI 4140 steel target to maintain 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 this probe can measure?
   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 for high-noise environments?
   No, the built-in EMI shielding ensures stable performance without external protection.

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

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

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

9. What signal conditioning equipment is recommended for proper operation?
   A Bently Nevada 3300 XL Proximitor or equivalent driver supplies power and processes the signal.

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