Features:

  • Interface Between the 330880‑28‑20‑038‑00‑02 PROXPAC XL Transducer and 3300/3500 Monitoring Systems
  • Combines Capability of Shaft Displacement and Vibration Measurement with 38 mm Probe Extension
  • Operates in Conjunction with 3300 XL and 3500 Series Monitors for Reliable Machine Condition Monitoring
The 330880‑28‑20‑038‑00‑02 operates as a precision PROXPAC XL proximity transducer assembly, providing accurate, non-contact shaft displacement and vibration measurement for critical rotating machinery. It continuously converts mechanical shaft motion into electrical signals through its 8 mm probe with 38 mm penetration and transmits these signals to the 3300/3500 monitoring system to support continuous machine protection and condition monitoring.

The 330880‑28‑20‑038‑00‑02 provides essential shaft displacement and vibration measurement functions for the entire monitoring system and is a critical component of the machine protection path, directly affecting the accurate operation of the 3300/3500 monitor system. One or more 330880‑28‑20‑038‑00‑02 transducer assemblies may be required per machine depending on the number of shafts and measurement points being monitored.

For critical machinery monitoring applications, the 3300/3500 system can be configured with multiple 330880‑28‑20‑038‑00‑02 transducer assemblies installed on redundant measurement points. In addition to standard single-probe operation, the redundant configuration ensures continuous shaft displacement and vibration monitoring even if one transducer fails.

The 330880-28-20-038-00-02 Bently Nevada PROXPAC XL proximity transducer assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
