Bently Nevada 330103-05-12-10-01-00
Complete Technical Specification, Product Overview, Applications and Advantages
1. Product Introduction
The 330103-05-12-10-01-00 is a precision eddy current proximity probe engineered for non‑contact measurement of shaft vibration, displacement, and position in rotating machinery.
This model is part of the 3300 XL 8 mm proximity probe series, a proven and widely used solution in industrial condition monitoring systems. The probe functions by creating a high‑frequency electromagnetic field at the tip. Changes in distance between the probe and a conductive shaft alter the field, producing a voltage signal proportional to the gap. This signal is then processed by condition monitoring equipment to determine vibration and position data.
The “05‑12‑10‑01‑00” configuration indicates this probe has specific cable and body length combinations, basic environmental options, and standard installation features tailored for general‑purpose industrial use.
