Bently Nevada 330780-50-05 3300 XL 11 mm Proximitor Sensor

Description

330780-50-05 is a 3300 XL 11 mm Proximitor Sensor configured for a 5.0 meter system length with panel mounting and multiple agency approvals (Option 05). This component serves as the central signal processing unit in the Bently Nevada 3300 XL 11 mm Proximity Transducer System, facilitating precise non-contact displacement and vibration measurements.

The Proximitor sensor provides a standardized 3.94 V per mm (100 mV per mil) output, maintaining system integrity across varying cable lengths. Designed to replace legacy 7200-series 11 mm and 14 mm transducer systems, this unit supports demanding industrial applications such as axial position, radial vibration, and Keyphasor phase reference measurements on fluid film bearing machinery. It features robust SpringLoc terminal strips for efficient field wiring and advanced RFI/EMI immunity, ensuring consistent performance without special mounting precautions.

Installation Guidelines

Ensure the extension cable length and the probe length, when added together, equal the Proximitor Sensor total system length. The sensor is designed for panel mounting. Use appropriate shielding for field wiring and ensure all connections are secure via the SpringLoc terminal strips. For hazardous area installations, adhere to the specific Bently Nevada drawings referenced in the system datasheet, ensuring the installation meets required IP54 protection ratings if applicable.
