3300 XL Proximity Probe System
Model: 330876-01-90-00-00
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 330876-01-90-00-00 is a proximity probe used in the 3300 XL eddy current transducer system. It is designed to measure shaft vibration, axial displacement, and rotor position in rotating machinery without physical contact.
It serves as the primary sensing element in a complete condition monitoring chain together with an extension cable and signal conditioning module.
Product Introduction
The 330876-01-90-00-00 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 in the surface, and the resulting changes are converted into a voltage signal proportional to the distance between probe and shaft.
The “90” configuration typically indicates a specialized probe design with extended sensing or modified mechanical configuration suitable for specific industrial installation requirements, often used in larger or more demanding machinery layouts.
This probe is designed for continuous operation in harsh industrial environments where reliability and measurement accuracy are critical.
