Features:

  • Interface Between the 330881‑28‑04‑034‑06‑02 PROXPAC XL Transducer and 3300/3500 Monitoring Systems
  • Combines Capability of Shaft Displacement and Vibration Measurement with 34 mm Probe Extension
  • Operates in Conjunction with 3300 XL and 3500 Series Monitors for Reliable Machine Condition Monitoring
The 330881‑28‑04‑034‑06‑02 operates as a precision PROXPAC XL proximity transducer assembly, providing continuous, non-contact measurement of shaft displacement and vibration for critical rotating machinery. It continuously converts mechanical shaft motion into electrical signals through its 8 mm probe with 34 mm penetration and transmits these signals to 3300 XL or 3500 Series monitoring systems to support reliable machine protection and condition monitoring.

The 330881‑28‑04‑034‑06‑02 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 3300 XL and 3500 Series monitors. One or more 330881‑28‑04‑034‑06‑02 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 330881‑28‑04‑034‑06‑02 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 330881‑28‑04‑034‑06‑02 Bently Nevada high-precision 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 probe, Proximitor® sensor, and optimized cabling into a single, factory-tested unit to ensure accurate signal transmission to Bently Nevada 3300 XL and 3500 Series monitoring systems.

With a 34 mm probe penetration, the 330881-28-04-034-06-02 is suitable for applications requiring short-to-medium reach, making it ideal for turbines, compressors, pumps, and generators where precise monitoring of shaft motion is critical. The assembly delivers repeatable and stable readings even under challenging operating conditions, including high vibration, temperature fluctuations, and electromagnetic interference.

The transducer’s rugged housing and standardized mounting provisions simplify installation while providing long-term stability and minimizing the need for frequent maintenance. By combining mechanical alignment, electrical signal conditioning, and a high-quality probe in a single assembly, this product reduces field wiring errors and installation complexity.

The 330881-28-04-034-06-02 supports machine protection, condition monitoring, and predictive maintenance programs, enabling early detection of imbalance, misalignment, bearing wear, or other mechanical anomalies. It provides reliable inputs to 3300 XL and 3500 Series monitors, helping ensure continuous machine protection, operational safety, and enhanced uptime.
