Product Introduction
Precision Eddy Current Technology for Critical Machinery
The 3300 XL 8mm Proximity Probe is engineered for continuous monitoring of rotating equipment where accurate shaft displacement information is essential. Its non-contact sensing principle eliminates mechanical wear between the probe and rotating shaft, ensuring stable measurement over long operating periods.
This model belongs to the 330101 series, which uses a 3/8-24 UNF threaded probe without armor and is optimized for standard mounting applications.
The probe supports applications such as:
-
Radial shaft vibration measurement
-
Shaft relative displacement monitoring
-
Rotor position measurement
-
Bearing vibration analysis
-
Keyphasor® phase reference applications
-
Turbine supervisory instrumentation (TSI)
The FluidLoc cable option improves resistance against oil and moisture migration through the cable structure, making it suitable for demanding machinery environments.

Advantages
Enhanced Fluid Resistance
The FluidLoc cable design helps prevent fluid migration along the cable, improving long-term reliability in oil-rich and industrial environments.
High Measurement Accuracy
The eddy current sensing technology provides precise distance measurement between the probe tip and rotating shaft, supporting accurate vibration analysis.
Non-Contact Operation
Because the probe does not physically contact the rotating component, it reduces mechanical wear and provides consistent performance during continuous operation.
Compact Installation Design
The standard 330101 configuration offers a practical mounting solution for installations where armored protection is unnecessary.
Compatible 3300 XL System Integration
The probe works with compatible 3300 XL extension cables and Proximitor Sensors, allowing easy integration into existing Bently Nevada monitoring systems.
