Overview Manuals Specifications
 

Features:

  • Interface Between the Proximity Probe and 3300 XL Monitor System
  • Combines Capability of Non-contact Vibration and Shaft Displacement Sensing with EMI‑Resistant Signal Transmission
  • Operates in Conjunction with 3300 XL 8 mm Proximity Probes and 3300 XL System Modules
The 330881‑01‑00‑000‑00‑02 operates as a Proxpac XL Proximity Transducer interface within the 3300 XL system, providing accurate non-contact vibration and shaft displacement measurements to the monitor modules. It converts probe signals into standardized outputs and transmits them through the system cabling to support reliable monitoring of critical rotating machinery. Seamless signal integrity is ensured under typical operating conditions, while enhanced EMI protection allows consistent performance in electrically noisy industrial environments. The 330881‑01‑00‑000‑00‑02 incorporates robust mounting and environmental sealing improvements over earlier Proximitor transducer designs, ensuring reliable operation in harsh conditions.

The 330881‑01‑00‑000‑00‑02 provides essential signal conditioning functions for the 3300 XL system, and is a critical component of the monitoring path, directly affecting the accurate measurement of vibration and shaft displacement. One or more 330881‑01‑00‑000‑00‑02 transducers may be installed per monitored axis depending on the required measurement configuration. The 330881‑01‑00‑000‑00‑02 mounts in standard sensor locations and is compatible with the system’s 3300 XL modules for seamless integration.

For critical monitoring applications requiring multiple sensor inputs, the 330881‑01‑00‑000‑00‑02 can be deployed alongside a second transducer per monitored axis to ensure redundant measurement coverage. In addition to standard single‑sensor operation, the redundant configuration performs automatic signal validation. The dual‑sensor setup continuously compares outputs from both transducers using the 3300 XL system’s internal diagnostic circuitry. If the system detects that the primary transducer signal deviates beyond configured thresholds, it automatically flags the secondary transducer as the active measurement source and logs an event in the System Event List.

The 330881‑01‑00‑000‑00‑02 Bently Nevada Universal AC Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
