Constructed from high-quality materials, the probe withstands high temperatures, vibration, and harsh operating environments.

System Compatibility
Fully compatible with Bently Nevada 3300 XL monitoring systems, allowing seamless integration into existing machinery protection setups.

Steam and gas turbines

Compressors and pumps

Electric motors and generators

Gearboxes and rotating shafts

API 670 compliant machinery protection systems

The probe is commonly used wherever early fault detection and condition-based maintenance are required.

Ensure the target surface is clean and free of oil, rust, or debris.

Avoid sharp bending or excessive pulling of the probe cable.

Do not exceed the specified temperature and environmental limits.

Perform regular system checks to confirm signal integrity and accuracy.

Following these guidelines helps maintain long-term measurement reliability.

The Bently Nevada 330104 proximity probe operates based on the eddy current principle. The probe tip generates a high-frequency electromagnetic field. When a conductive target, such as a rotating shaft, enters this field, eddy currents are induced on the target surface.

As the distance between the probe and the target changes, the strength of the eddy currents also changes. This variation alters the electrical characteristics of the probe, which are converted into a voltage signal proportional to the gap distance. The resulting signal accurately represents shaft position or vibration and is processed by the monitoring system for analysis and protection functions.
