Hardware Specifications

Rotor Dynamics & Eddy-Current Proximity Transducer Scaling

The Bently Nevada 3300 XL proximity transducer system processes high-frequency radio frequency signals generated by the proximitor sensor to monitor static and dynamic displacement of rotating shafts. The eddy-current probe scaling is calibrated precisely to 7.87 V/mm (200 mV/mil), establishing a linear operating range of 2.0 mm. Gap voltage validation targets -10 VDC under nominal operating conditions, ensuring optimal linearity across radial vibration and axial thrust measurements. Cross-talk suppression mechanisms are embedded within the multi-conductor shielded architecture, preventing electromagnetic interference from adjacent high-voltage machinery lines or variable frequency drives in industrial compressor and turbine skids.

Kit Contents & Delivery Components

Mechanical Mounting & Electrical Installation Guidelines

• Ensure the probe tip is mounted perpendicularly to the observed rotor target surface to maintain linear scale factor accuracy.
• Maintain a minimum radial clearance distance of 25 mm from adjacent structural boundaries to prevent stray eddy-current field distortion.
• Torque threaded probe bodies using calibrated open-end wrenches according to specified thread pitch tolerances (e.g., 3/8-24 UNF).
• Route the low-noise coaxial extension cables through dedicated grounded metallic conduit, completely segregated from AC power wiring.
• Terminate shield drain wires exclusively at the instrument rack barrier earth terminal to avoid ground loop current induction.
