Bently Nevada 330103-02-08-10-02-RU 3300 XL 8mm Proximity Probes

Product Introduction

The Bently Nevada 330103-02-08-10-02-RU 3300 XL 8mm Proximity Probe is a precision sensor engineered for accurate measurement of shaft vibration and displacement in critical rotating machinery. Belonging to the 3300 XL series, this probe ensures reliable, repeatable measurements required for machinery protection, predictive maintenance, and operational efficiency.

This probe uses eddy current technology to convert the distance between the probe tip and the rotating shaft into an electrical signal with high fidelity. Its total length of 1 meter and weight of 0.323 kg make it suitable for medium-range installations while ensuring signal stability. The stainless steel housing provides durability against corrosion, vibration, and industrial stress. The RU designation indicates compliance with Russian industrial standards. The probe is fully compatible with Proximitor sensors and 3300 XL monitoring systems, providing high-accuracy data for early fault detection and machinery health monitoring.

FAQ

1. What sensing principle does this probe use?
It uses eddy current technology to measure the gap between the probe tip and the shaft surface.

2. What is the linear measurement range?
The typical linear range is 2 mm when used with a compatible Proximitor sensor.

3. How does the 1-meter cable affect calibration?
The probe and cable are factory-matched to ensure calibration stability across the full cable length.

4. Can it measure both radial and axial shaft movement?
Yes, installation orientation determines whether it measures radial vibration or axial displacement.

5. What type of electrical output does the probe provide?
It generates a voltage signal proportional to shaft displacement.

6. How does it handle electromagnetic interference?
The shielded cable reduces EMI and maintains accurate signal transmission in electrically noisy environments.

7. Is it suitable for high-vibration environments?
Yes, it operates reliably under vibration levels up to 10 g across 10–2000 Hz.

8. What is the operating temperature range?
It operates reliably from –35 °C to +180 °C.

9. Can it be used with legacy Bently Nevada systems?
Yes, it is compatible with both 3300 and 3500 series monitoring systems.

10. What industry standards does this probe comply with?
It meets API 670 standards for vibration and displacement monitoring in rotating machinery.
