Features:

  • Interface Between the 330881-BR-07-155-06-02 PROXPAC XL Assembly and 3300 XL / 3500 Monitoring Systems
  • Combines Capability of 8 mm Proximity Sensing with Integrated Shaft Displacement and Vibration Measurement
  • Operates in Conjunction with Standard 3300 XL and 3500 Series Monitors for Critical Machinery Protection
The Bently Nevada 330881-BR-07-155-06-02 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 via its 8 mm probe and internal Proximitor sensor, delivering reliable outputs to 3300 XL and 3500 Series monitoring systems.

The Bently Nevada 330881-BR-07-155-06-02 provides essential shaft displacement and vibration measurement functions for critical rotating machinery, and is a key component of the monitoring path, directly affecting the accurate operation of the overall condition monitoring system. One or more 330881-BR-07-155-06-02 assemblies are installed per machine depending on the number of measurement points and required redundancy. The assembly is compact, factory-configured, and designed for straightforward integration with 3300 XL and 3500 Series monitoring systems, ensuring reliable, long-term performance.

For dual-redundant monitoring applications, the Bently Nevada 330881-BR-07-155-06-02 can be deployed in a second assembly to provide backup measurement capability. In addition to standard single-probe operation, the redundant configuration allows automatic switchover if the primary transducer assembly fails or its output signal falls outside specified displacement or vibration tolerances.

The 330881-BR-07-155-06-02 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).

Description
This assembly integrates an 8 mm PROXPAC XL probe with an internal Proximitor sensor and pre-terminated cabling, providing a compact, factory-tested solution that minimizes installation complexity and wiring errors. It delivers reliable signals directly to 3300 XL and 3500 Series monitoring systems, ensuring effective condition monitoring and machinery protection.

With a 155 mm probe penetration length, this assembly is ideal for applications requiring extended reach into large bearing housings or deep machine cavities. The 8 mm probe utilizes eddy current sensing technology to convert mechanical shaft motion into precise electrical signals, offering high-resolution measurements of both shaft displacement and vibration. This capability enables early detection of machinery issues such as imbalance, misalignment, or bearing wear.

Built with robust, industrial-grade materials, the 330881-BR-07-155-06-02 assembly withstands harsh environmental conditions, including extreme temperatures, vibration, dust, and moisture. Its sealed and durable design ensures long-term reliability in power generation, petrochemical, and heavy industrial environments. By combining sensing and signal conditioning in a single assembly, this product reduces installation time, improves signal integrity, and provides consistent performance over the lifecycle of critical rotating equipment.

The 330881-BR-07-155-06-02 is a key component for predictive maintenance programs, helping operators maintain machine uptime, prevent unplanned outages, and enhance operational safety through continuous monitoring of shaft position and vibration trends.
