Quick Detail

Description

The 330881-BR-05-090-00-02 PROXPAC XL Proximity Transducer is an advanced self-contained eddy current sensing assembly designed for industrial automation, predictive maintenance, and turbomachinery monitoring. Unlike traditional proximity probe systems, this transducer integrates a 3300 XL Proximitor Sensor directly within its housing, eliminating the need for separate extension cables or external Proximitor enclosures. Constructed from Polyphenylene Sulfide (PPS) reinforced with glass and conductive fibers, the housing provides IP66 protection and Type 4X rating, ensuring durability in harsh industrial environments. With a linear range of 2 mm, recommended gap setting of 1.27 mm, and shaft diameter compatibility from 50.8 mm to 76.2 mm, the PROXPAC XL delivers precise shaft position, vibration, and Keyphasor measurements. Its operating temperature range from −52°C to +100°C and low supply sensitivity (<2 mV/V) enable reliable performance across gas turbines, compressors, pumps, and rotating machinery in oil & gas, petrochemical, and power generation industries. The assembly’s modular design simplifies field wiring, reduces installation time, and supports seamless integration with automated monitoring systems.

Applications

Application 1 Self-Contained Shaft Vibration Measurement
The PROXPAC XL assembly directly measures shaft displacement and vibration on turbines, providing accurate real-time data that can reduce unplanned downtime by 15–20% in continuous-duty power generation equipment.

Application 2 Compressor Rotor Position Monitoring in Harsh Environments
With IP66 and Type 4X protection, the assembly withstands corrosive or wet conditions while delivering reliable rotor position data, enhancing bearing film stability and operational efficiency by 8–12%.

Application 3 Integrated Pump Condition Monitoring
By combining probe and Proximitor into a single unit, the transducer allows precise predictive maintenance on refinery and industrial pumps, lowering corrective maintenance events by 25–30% and extending MTBF.

Application 4 Keyphasor Reference for Automated Control Loops
The transducer provides accurate phase and speed reference signals for Keyphasor applications, achieving ±0.1% measurement precision during start-up and transient machine operation for automated control systems.

Application 5 Simplified Field Wiring for Industry 4.0 Monitoring
Eliminating the need for separate Proximitor sensors and extension cables reduces installation complexity and supports digital twin integration, improving plant-wide predictive maintenance efficiency by 10–15%.
