Overview Manuals Specifications
 

Features:

  • Interface Between the 330881‑28‑04‑150‑06‑02 PROXPAC XL Transducer and 3300/3500 Monitoring System
  • Combines Capability of Shaft Displacement and Vibration Measurement with Extended Probe Reach
  • Operates in Conjunction with 3300 XL and 3500 Series Monitors for Machine Condition Monitoring
The 330881‑28‑04‑150‑06‑02 operates as a precision PROXPAC XL proximity transducer assembly for the 3300 and 3500 monitoring systems, providing accurate shaft displacement and vibration measurement for critical rotating machinery. It integrates an 8 mm probe with a 150 mm probe extension and distributes the measurement signals through the machine’s monitoring system to support continuous condition monitoring and predictive maintenance.

The 330881‑28‑04‑150‑06‑02 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 the overall 3300/3500 monitor system. One or more 330881‑28‑04‑150‑06‑02 transducer assemblies may be required per machine depending on the number of monitored shafts and measurement points.

For critical machinery monitoring applications, the 3300/3500 system can be configured with multiple 330881‑28‑04‑150‑06‑02 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 330881-28-04-150-06-02 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
It features a 3300 XL 8 mm probe with multiple approvals and a linear output with an incremental scale factor of 7.87 V/mm (200 mV/mil) ±5%, covering a linear range of 0.25 mm to 2.3 mm (10 mils to 90 mils). 

The sensor includes a standoff adapter (40 mm) and comes with a fittings kit including a 3/4-14 NPT fitting, a 3/4-14 NPT to 1/2-14 NPT stainless steel reducer, and two plugs. Its PPS housing and Type 4X/IP66 ingress protection ensure reliable operation in harsh industrial environments, while support for field wiring up to 305 meters (1,000 ft) allows flexible installation in machinery monitoring systems.

The Bently Nevada 330881‑28‑04‑150‑06‑02 is a factory‑built PROXPAC XL proximity transducer assembly designed for precision shaft displacement and vibration measurement on critical rotating machinery. It integrates a 3300 XL 8 mm probe with a 40 mm standoff adapter and a long 150 mm probe penetration length, making it ideal for applications where greater measurement reach is required.

This transducer assembly includes a ready‑to‑install housing with the probe, fittings kit (including 3/4‑14 NPT fitting, 3/4‑14 NPT to 1/2‑14 NPT reducer, and plugs), and a standard mounting thread size of 3/4‑14 NPT, facilitating straightforward connection to lubrication probe mounts or proximity housings. Its robust design supports reliable operation in industrial environments where accurate condition monitoring contributes to predictive maintenance and machine protection programs.
