3300 XL Proximity Probe System
Model: 330876-01-50-00-05
Brand Information
Brand: Bently Nevada
Series: 3300 XL Proximity Transducer System (Proximity Probe Assemblies)
Product Category: Eddy Current Proximity Probe
System Role: Non-contact vibration and shaft displacement sensing element
The 330876-01-50-00-05 is a proximity probe designed for the 3300 XL eddy current measurement system. It is used to monitor shaft vibration, axial movement, and rotor position in rotating machinery through non-contact sensing technology.
It operates as the primary sensing element in a complete proximity system, working together with an extension cable and signal processing module.
Product Introduction
The 330876-01-50-00-05 proximity probe is engineered for high-accuracy measurement of rotating shaft behavior. It uses eddy current technology to detect minute changes in distance between the probe tip and a conductive target surface.
When the shaft vibrates or shifts position, the electromagnetic field changes, and the probe converts this change into a proportional electrical signal. This signal is then transmitted to a proximitor for processing and condition monitoring.
The “50” configuration typically indicates a longer probe or extended sensing range variant compared to standard models, making it suitable for larger machinery or installations requiring deeper mechanical reach or different mounting configurations.
It is widely used in heavy-duty rotating equipment operating under continuous industrial conditions.
