Features:

  • Interface Between the 330881-28-04-145-06-02 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 330881-28-04-145-06-02 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 precise output to connected 3300 XL or 3500 Series monitoring systems.

The Bently Nevada 330881-28-04-145-06-02 provides essential 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 330881-28-04-145-06-02 assemblies are installed per machine depending on the number of measurement points and desired redundancy. The assembly is compact, factory-configured, and designed for easy integration into 3300 XL or 3500 Series monitoring systems, ensuring consistent, reliable performance.

For critical machinery protection applications, the Bently Nevada 330881-28-04-145-06-02 can be installed in dual-probe configurations to support redundant shaft displacement and vibration measurement. In addition to standard single-assembly operation, the redundant configuration ensures continuous monitoring in the event of a primary probe or signal path failure.

The 330881-28-04-145-06-02 Bently Nevada PROXPAC XL 8 mm proximity transducer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
This assembly integrates a high-resolution 8 mm probe, an internal Proximitor® sensor, and pre-terminated cabling into a single, ready-to-install unit. By providing a complete factory assembly, it minimizes field wiring complexity and reduces the potential for installation errors, ensuring reliable signal transmission to connected monitoring systems.

With a 145 mm probe penetration length, this configuration is ideal for applications that require deep reach into bearing housings or other constrained areas. The 8 mm probe converts mechanical shaft motion into proportional electrical signals, which are processed by the internal Proximitor® to provide accurate and repeatable measurements. This ensures seamless integration with 3300 XL or 3500 Series monitoring systems, delivering high-fidelity vibration and displacement data for machinery protection and condition monitoring.

The PROXPAC XL assembly is built from robust, industrial-grade materials to withstand harsh operational environments, including extreme temperatures, vibration, and exposure to dust or moisture. The durable construction, combined with the sealed probe design, ensures long-term reliability and consistent performance even in demanding industrial applications such as power generation, petrochemical, and process industries.

By combining the sensing probe and signal conditioning into a single compact assembly, the 330881-28-04-145-06-02 simplifies installation, improves measurement stability, and enhances overall monitoring system reliability. It enables early detection of machinery issues such as misalignment, imbalance, bearing wear, or other mechanical anomalies, helping prevent unplanned downtime and reduce maintenance costs.
