3300 XL Proximity Probe System
Model: 330876-01-90-00-05
Brand Information
Brand: Bently Nevada
Series: 3300 XL Proximity Transducer System (Proximity Probe Assemblies)
Product Category: Eddy Current Proximity Probe
System Role: Non-contact shaft vibration and displacement sensing element
The 330876-01-90-00-05 is a proximity probe designed for the 3300 XL eddy current transducer system. It is used for high-precision measurement of shaft vibration, axial displacement, and rotor position in rotating machinery.
It functions as the primary sensing element in a complete monitoring chain together with an extension cable and signal conditioning module.
Product Introduction
The 330876-01-90-00-05 proximity probe operates based on eddy current measurement principles. It generates a high-frequency electromagnetic field at the probe tip. When a conductive shaft enters this field, eddy currents are induced, and changes in the field are converted into electrical signals proportional to the gap distance.
The “90” configuration typically indicates a specialized probe variant designed for extended or optimized installation conditions in large industrial machinery systems, while the “05” suffix defines a specific configuration variant within the assembly structure.
This probe is engineered for continuous operation in harsh environments where vibration, temperature fluctuations, oil exposure, and mechanical stress are common.
