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

Product Introduction

The Bently Nevada 330906-02-12-10-12-RU 3300 NSv Reverse Mount Probe is a precision-engineered, non-contact eddy-current sensor specifically designed for reverse mounting in critical rotating machinery. This model enables installation in restricted or unconventional locations where standard probe orientation is not feasible. As part of the 3300 NSv (Narrow Side-view) series, it provides highly reliable shaft vibration and displacement measurements, ensuring early detection of mechanical issues such as rotor imbalance, misalignment, and bearing wear. Built to withstand harsh industrial environments, this probe features robust stainless-steel construction and integrated electromagnetic interference (EMI) protection, making it a critical component for predictive maintenance and machinery protection programs.

Product Specifications

Applications

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

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

• Electric Motors and Generators: Tracks rotor displacement and vibration for improved operational reliability in tight spaces.

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

• Industrial Pumps: Provides accurate monitoring of hydraulic instabilities and shaft deflection in confined or reverse-mount locations.

• Fans and Blowers: Delivers early warning of imbalance or bearing wear in areas unsuitable for standard probe mounting.

Advantages

• Reverse Mount Capability: Designed specifically for constrained or unconventional mounting requirements.

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

• Compact and Durable: 5 mm probe tip allows installation in limited space; stainless-steel construction ensures long-term reliability.

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

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

• Seamless System 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-RU probe calibrated for accurate displacement measurement?
   Each unit is factory-calibrated using an AISI 4140 steel target to ensure linearity and sensitivity.

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

3. What is the maximum measurable vibration frequency for 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 the probe be installed in pressurized or oil-submerged environments?
   Yes, it is rated up to 500 psi and suitable for submerged or pressurized applications.

7. How is measurement accuracy maintained across wide temperature variations?
   Internal thermal compensation and stainless-steel construction preserve accurate measurements across the operating range.

8. Can the probe measure 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 performance?
   A Bently Nevada 3300 XL Proximitor or equivalent driver provides the necessary power and signal processing.

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 extension cable is essential.
