Bently Nevada 20929-02 3000 Series Proximitor Transducer

Summary: The Bently Nevada 20929-02 Proximitor transducer converts eddy current probe signals into precise vibration readings. Engineers deploy this unit within 3000 Series systems to monitor critical shaft position and radial dynamic motion without physical mechanical contact.

Core Operational Capabilities

• Engineers design the 20929-02 module to process continuous vibration signals across a broad response range from 0 Hz to 10 kHz.
• Solid-state internal electronics eliminate moving parts, preventing mechanical degradation and minimizing long-term signal drift during continuous machinery operation.
• The transducer accurately captures dynamic motion parameters including vibration amplitude, signal phase angle, and spectral frequency distributions.
• Operators track static shaft position alongside dynamic radial movement to prevent catastrophic bearing failure in heavy industrial rotating assets.
