Features:

  • Interface Between the 330881-BR-04-034-06-02 PROXPAC XL Assembly and 3300 XL / 3500 Monitoring Systems
  • Combines Capability of 8 mm Proximity Sensing with Integrated Signal Conditioning
  • Operates in Conjunction with Standard 3300 XL and 3500 Series Monitors for Shaft Displacement and Vibration Measurement
The Bently Nevada 330881-BR-04-034-06-02 functions as a fully integrated 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 high-resolution electrical signals using its 8 mm probe and internal Proximitor sensor, delivering precise output to 3300 XL or 3500 Series monitoring systems.

The Bently Nevada 330881-BR-04-034-06-02 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 overall monitoring system. One or more 330881-BR-04-034-06-02 assemblies are installed per machine depending on the number of measurement points and redundancy requirements. The assembly is compact, factory-configured, and designed for straightforward integration into 3300 XL or 3500 Series monitoring systems, ensuring consistent, reliable performance.

For critical machinery monitoring applications, the Bently Nevada 330881-BR-04-034-06-02 can be deployed in dual-redundant configurations to ensure continuous shaft displacement and vibration measurement. In addition to standard single-probe operation, the redundant configuration allows automatic switchover if the primary transducer assembly fails or its output falls outside specified signal tolerances.

The 330881-BR-04-034-06-02 Bently Nevada integrated 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).

Description
This assembly combines a 3300 XL 8 mm proximity probe, an internal Proximitor sensor, and factory-terminated cabling into a single compact unit, simplifying installation and minimizing potential wiring errors. It delivers high-fidelity signals to 3300 XL and 3500 Series monitoring systems, ensuring reliable condition monitoring and machinery protection.

The 34 mm probe penetration length makes this assembly ideal for applications with shallow installation requirements, such as smaller bearing housings or compact machinery enclosures. The 8 mm probe uses eddy current sensing technology to convert mechanical shaft motion into precise electrical signals, providing high-resolution measurements of both shaft displacement and vibration. This ensures early detection of machinery issues, including imbalance, misalignment, or bearing wear.

Constructed from robust industrial-grade materials, the 330881-BR-04-034-06-02 assembly withstands harsh operating conditions, including extreme temperatures, vibration, dust, and moisture. Its sealed design ensures long-term reliability in power generation, petrochemical, and heavy industrial applications.

By integrating both sensing and signal conditioning into a single assembly, this product reduces installation complexity, enhances signal reliability, and provides consistent performance over time. The 330881-BR-04-034-06-02 enables operators to implement effective predictive maintenance programs, improving machine uptime, reducing unplanned outages, and maintaining operational safety in critical rotating equipment.
