Features:

  • Interface Between the 330881-28-07-155-06-02 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 330881-28-07-155-06-02 operates as a fully integrated PROXPAC XL proximity transducer assembly, providing accurate shaft displacement and vibration measurement for critical rotating machinery. It continuously converts mechanical shaft motion into proportional electrical signals through its 8 mm probe and internal Proximitor sensor, delivering high-resolution output to the connected 3300 XL or 3500 Series monitoring systems.

The Bently Nevada 330881-28-07-155-06-02 provides essential shaft displacement and vibration sensing functions for the overall monitoring system, and is a critical component in ensuring accurate condition monitoring of rotating machinery. One or more 330881-28-07-155-06-02 assemblies may be required per machine depending on the number of measurement points and system redundancy needs.

For critical machinery monitoring applications, the Bently Nevada 330881-28-07-155-06-02 system can be configured with multiple PROXPAC XL assemblies installed for redundant shaft displacement and vibration measurement. In addition to standard single-probe operation, the redundant configuration ensures continuous monitoring even if one probe or assembly fails.

The 330881-28-07-155-06-02 Bently Nevada internal Proximitor sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
This integrated assembly combines a 3300 XL 8 mm proximity probe, an internal Proximitor® sensor, and factory-configured cabling into a single, compact housing. The pre-engineered configuration eliminates the need for separate extension cables and external probe housings, reducing installation complexity and minimizing wiring errors in the field.

Featuring a 155 mm probe penetration length, this configuration is suitable for applications requiring extended reach into bearing housings or machine casings. The 8 mm probe delivers high-resolution eddy current measurement, converting mechanical shaft motion into proportional electrical output signals that interface directly with 3300 XL and 3500 Series monitoring systems. This ensures reliable data transmission for continuous vibration and displacement monitoring.

The PROXPAC XL housing is constructed from durable, industrial-grade materials designed to withstand harsh environments, including vibration, temperature variations, and exposure to contaminants. Its sealed design enhances resistance to moisture and dust, supporting long-term operation in demanding power generation, oil and gas, and process industry installations.

By integrating sensing and signal conditioning into a single assembly, the 330881-28-07-155-06-02 improves measurement stability, simplifies commissioning, and enhances overall system reliability. It plays a critical role in machine protection strategies by enabling early detection of imbalance, misalignment, shaft rub, and bearing wear—helping operators prevent unexpected failures and reduce downtime in high-value rotating equipment.
