Product Overview
In critical industrial equipment, accurate vibration and displacement measurement are essential for preventing unexpected failures and improving machinery reliability. The Bently Nevada 330701-00-40-10-11-05 3300 XL 11 mm Eddy Current Probe is a high-performance non-contact proximity probe designed for monitoring the condition of rotating machinery.
Using advanced eddy current sensing technology, the probe detects the distance between the probe tip and the rotating shaft surface without physical contact. It converts shaft movement into electrical signals, allowing monitoring systems to analyze vibration, displacement, and machine operating conditions.
The 3300 XL 11 mm Eddy Current Probe is widely applied in large rotating equipment where accurate and continuous condition monitoring is required, including turbines, compressors, pumps, generators, and industrial rotating machinery.
Compared with smaller sensing probes, the 11 mm probe design provides an extended measurement range, making it suitable for applications requiring larger installation distances or greater measurement flexibility.
The Bently Nevada 330701-00-40-10-11-05 is typically integrated into a complete vibration monitoring system together with extension cables, signal conditioning devices, and machinery protection monitoring equipment.

Function and Working Principle
The Bently Nevada 330701-00-40-10-11-05 operates based on the principle of eddy current measurement.
The probe generates a high-frequency electromagnetic field at the sensing tip. When the metallic shaft surface moves within this electromagnetic field, the generated eddy current changes according to the distance between the probe and the target surface.
The system converts these changes into electrical output signals representing shaft movement and vibration conditions.
