Bently Nevada 330851-06-00-80-50-01-00 3300 XL 25 mm Proximity Probe

Description

Industrial machinery monitoring applications rely on the 330851-06-00-80-50-01-00 for high-precision displacement and vibration measurements. As a core component of the Bently Nevada 3300 XL 25 mm Proximity Transducer System, this non-contacting eddy current sensor detects static and dynamic shaft movement. It is engineered to perform reliably under the demanding physical and thermal conditions found in heavy industrial rotating machinery, such as steam turbines, gas turbines, and large compressors.

This specific configuration is built with an M39x1.5 threaded case, an 80 mm overall case length, and a 5.0-meter total system length protected by stainless steel armor. By delivering high-resolution electrical signals proportional to the distance between the probe tip and the target material, it enables plant operators to detect early signs of mechanical wear, misalignment, and bearing degradation.

Features

• Highly stable transducer design calibrated for non-contact displacement measurements.
• Robust stainless steel armor (SST Armor) provides excellent mechanical and environmental protection for the extension cable.
• Optimized for fluid-film bearing monitoring in severe industrial environments.
• Consistent electrical performance over wide operating temperature ranges.

Applications

• Turbine shaft vibration and thrust position monitoring.
• Radial vibration and axial position sensing in large compressors.
• Condition monitoring for critical pumps and generators in oil, gas, and power generation facilities.
• High-speed rotary machine protection systems.

Installation Guidelines

• Thread Alignment: Carefully align the M39x1.5 threads when mounting the probe to prevent cross-threading and ensure proper physical alignment with the target shaft.
• Minimum Clearance: Observe official Bently Nevada recommendations for lateral clearance to adjacent metal structures to avoid side-viewing interference.
• Cable Routing: Avoid sharp bends in the armored cable. Maintain minimum bending radius specifications to protect the internal coaxial signal path.
• Connector Maintenance: Ensure probe-to-extension cable connectors remain clean, dry, and free of oil or contaminants during installation.
