3300 XL 11 mm Proximity Probe
Model: 330801-28-04-050-00-02
Brand Information
Brand: Bently Nevada
Series: 3300 XL 11 mm Proximity Transducer System
Product Category: Industrial Non-Contact Proximity Probe
Product Type: Eddy Current Shaft Vibration and Displacement Sensor
The 330801-28-04-050-00-02 is a precision-engineered proximity probe designed for continuous monitoring of rotating machinery. As part of the 3300 XL 11 mm Series, this probe provides highly accurate non-contact measurements of shaft vibration, shaft position, eccentricity, rotor dynamics, and axial displacement.
The probe is intended for critical industrial applications where equipment reliability, machinery protection, and predictive maintenance are essential. Its rugged mechanical construction and advanced sensing technology enable stable performance in harsh operating environments such as power plants, petrochemical facilities, offshore platforms, compressor stations, and manufacturing plants.
Product Introduction
The 330801-28-04-050-00-02 utilizes advanced eddy current sensing technology to measure the distance between the probe tip and a conductive target surface. During operation, the sensor generates a high-frequency electromagnetic field. Variations in shaft position cause corresponding changes in the electromagnetic field, which are converted into highly accurate electrical signals.
Because the probe operates without physical contact, it eliminates wear and friction associated with mechanical measurement devices. This design significantly improves reliability and extends service life while maintaining excellent measurement repeatability.
The larger 11 mm probe diameter allows enhanced sensing capability and improved signal stability, particularly in applications involving large shafts, heavy rotating machinery, and high-vibration environments. The probe continuously provides real-time data to monitoring systems, enabling operators to detect imbalance, misalignment, bearing wear, shaft movement, and other developing machinery issues.
Its robust stainless-steel housing and industrial-grade construction ensure dependable operation in environments exposed to oil contamination, dust, moisture, temperature fluctuations, and continuous vibration.
