Bently Nevada 330105-02-12-05-12-RU 3300 XL 8 mm Reverse Mount Probes

Product Introduction

The Bently Nevada 330105-02-12-05-12-RU is an 8 mm reverse mount proximity probe from the 3300 XL series, designed for high-accuracy non-contact measurement of shaft vibration and displacement in critical rotating machinery. The reverse mount configuration allows installation in tight or reverse-facing locations where standard probes cannot fit, providing flexibility without compromising measurement accuracy.

With a total cable length of 0.5 meters and robust stainless-steel construction, the probe delivers stable output, low electrical noise, and rapid response. It is optimized for integration with the 3300 XL monitoring system, making it suitable for predictive maintenance, machinery protection, and condition monitoring in demanding industrial environments.

FAQ

1. How does the 330105-02-12-05-12-RU probe measure shaft vibration?
   It uses the eddy current principle, producing a voltage proportional to the distance between the probe tip and the conductive shaft surface.

2. Which shaft materials are compatible with this probe?
   Conductive metals, primarily steel, are suitable for accurate displacement and vibration measurements.

3. What is the probe’s frequency response range?
   The probe operates from DC to 20 kHz, capturing both slow shaft movements and high-frequency vibrations.

4. Can it monitor both radial and axial shaft displacement?
   Yes, the orientation of the probe determines whether it measures radial vibration or axial displacement.

5. How is linearity maintained across the measurement range?
   The combination of probe design and 3300 XL system linearization ensures accuracy within ±1% of full-scale displacement.

6. Is it compatible with other Bently Nevada monitoring systems?
   It is optimized for 3300 XL systems but can interface with systems that accept standard voltage output.

7. How does the probe handle electromagnetic interference (EMI)?
   Shielded cabling and robust internal electronics minimize the effect of EMI and RFI, providing stable signals.

8. Can the probe operate in high-temperature environments?
   Yes, the probe can operate reliably up to +120 °C at the tip.

9. Is recalibration required after installation?
   Factory calibration ensures accurate output; routine verification is recommended according to maintenance standards.

10. What is the main advantage of the reverse mount design?
    It allows installation in constrained or reverse-facing positions without compromising measurement accuracy, ideal for compact or complex machinery layouts.
