Description

Product Overview

The Bently Nevada 330881-28-05-090-00-02 represents a high-performance PROXPAC XL assembly, specifically engineered to consolidate a 3300 XL Proximitor Sensor within a ruggedized protective enclosure. By integrating these components, the system facilitates direct machinery mounting, which effectively shields the internal electronics from harsh industrial atmospheres while providing high-precision displacement data. This transducer assembly plays a vital role in monitoring shaft vibration, axial position, and rotational speed for critical rotating assets such as turbines, compressors, and large industrial motors.

Operational Engineering and Utility

The design of the 330881 series prioritizes mechanical resilience and signal stability. Because the Proximitor Sensor resides inside the weather-resistant housing, the assembly eliminates the requirement for external junction boxes or separate sensor housings. This streamlined approach significantly simplifies field wiring and reduces potential points of failure caused by moisture ingress or physical impact. Furthermore, the 5.0-meter system length calibration ensures seamless electrical matching with standard 3300 XL extension cables and probes, maintaining a linear voltage output proportional to the gap between the probe and the target material.

Key Technical Characteristics

• Integrated Protection: Combines the sensor and housing into a single unit to defend against dust, chemicals, and mechanical stress.
• Structural Integrity: The assembly demonstrates exceptional durability, capable of sustaining mechanical loads of up to 912 N (205 lbf) without compromising measurement accuracy.
• Horizontal Orientation: Specifically configured for horizontal mounting, making it suitable for particular machine casing geometries and limited-space environments.
• Precision Measurement: Operates on the 3300 XL platform to provide a consistent, linear output for Turbine Supervisory Instrumentation (TSI) and general machinery protection.
• Simplified Installation: Reduces the overall footprint of the monitoring system and lowers installation costs by removing the need for auxiliary mounting hardware.
