3300 XL 11 mm Proximity Probe
Model: 330801-28-04-150-06-02
Brand Information
Brand: Bently Nevada
Series: 3300 XL 11 mm Proximity Transducer System
Product Category: Eddy Current Non-Contact Proximity Probe
Application: Rotating Machinery Vibration and Shaft Position Monitoring
The 330801-28-04-150-06-02 is a heavy-duty industrial proximity probe designed for long-reach installation and high-accuracy monitoring of shaft vibration, displacement, and rotor dynamics. It belongs to the 3300 XL 11 mm series, which is widely used in critical machinery protection systems across energy, oil & gas, petrochemical, and heavy industrial sectors.
This model is engineered for environments where extended installation depth is required and where mechanical stability, measurement accuracy, and long-term reliability are essential.
Product Introduction
The 330801-28-04-150-06-02 operates using eddy current sensing technology, which generates a high-frequency electromagnetic field at the probe tip. When a conductive target such as a rotating shaft enters the field, the variation in distance changes the electrical signal output proportionally.
This non-contact measurement method eliminates mechanical wear and ensures stable long-term operation even in harsh industrial environments. The probe continuously measures shaft vibration and displacement, transmitting real-time data to monitoring systems for analysis and protection functions.
The 150 mm extended body design is one of the longest configurations in the 11 mm series, making it suitable for deep-mounted machinery structures, thick housings, and complex installation layouts where standard probes cannot reach the target surface.
It is widely used in turbines, compressors, generators, pumps, and other high-value rotating equipment requiring continuous condition monitoring.
