Product Introduction
The Bently Nevada 330103-02-07-50-02-00 3300 XL 8mm Proximity Probe is a precision-engineered sensor designed for accurate measurement of shaft vibration and displacement in critical rotating machinery. As a member of the 3300 XL series, this probe provides high reliability, consistent measurement performance, and robust operation in demanding industrial environments.
This probe employs eddy current technology to detect the gap between the probe tip and the rotating shaft. Its 5-meter total length and 1.615 kg weight make it suitable for installations where long-distance cable routing is required without compromising signal integrity. The stainless steel housing ensures durability against corrosion, vibration, and mechanical stress. This model is optimized for integration with Proximitor sensors and 3300 XL monitoring systems, providing stable, high-fidelity data for machinery protection and predictive maintenance programs.

FAQ
1. What measurement principle does this probe use?
It uses eddy current technology to detect 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 paired with a matching Proximitor sensor.
3. How does the 5-meter cable length affect signal transmission?
The probe and cable are factory-matched to ensure minimal signal loss over the 5-meter distance.
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 the probe handle electromagnetic interference?
The probe has shielding to maintain signal accuracy in environments with electrical noise.
7. Is it suitable for high-vibration machinery environments?
Yes, it is designed to operate 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.
