Quick Detail

Description

The PROXPAC XL Proximity Transducer (330880-28-20-038-00-02) is a high-performance, compact proximity measurement device designed for industrial automation and critical rotating machinery monitoring. Featuring a 38 mm probe penetration with a 20 mm standoff adapter, this transducer provides precise shaft vibration and position measurements in constrained or recessed mounting locations. The assembly integrates a 3300 XL 8 mm Proximitor sensor with multiple approvals, enabling stable, accurate output while eliminating the need for separate Proximitor housings or extension cables.

Constructed from Polyphenylene Sulfide (PPS) reinforced with glass and conductive fibers, the PROXPAC XL housing ensures high mechanical strength, chemical resistance, and effective electrostatic charge dissipation. It is rated IP66 and Type 4X, ensuring reliable operation in dusty, wet, or harsh industrial environments.

Electrical specifications include supply sensitivity < 2 mV per volt, output resistance of 50 Ω, and compatibility with 16–24 AWG (0.2–1.5 mm²) field wiring, providing low-noise, high-precision measurements. The transducer supports a linear range of 2 mm (80 mils) with a recommended gap setting of 1.27 mm (50 mils), and accommodates shafts from 50.8 mm (2.0 in) minimum to 76.2 mm (3.0 in) recommended. Operating temperatures range from -52°C to +100°C (-62°F to +212°F), making this device ideal for turbines, motors, pumps, and compressors in automated condition monitoring systems.

Applications

1. Compact Motor Shaft Monitoring
The 20 mm standoff adapter and 38 mm probe penetration allow accurate monitoring of motor shafts in limited-space installations, ensuring early detection of imbalance or misalignment.

2. Turbine Vibration Analysis
Integrated 3300 XL sensor enables continuous, high-resolution vibration measurement on turbine shafts, supporting automated predictive maintenance and reducing downtime.

3. Pump and Compressor Condition Monitoring
Compact housing allows installation in tight pump and compressor assemblies while delivering precise shaft displacement data for performance optimization.

4. Harsh Environment Operations
With IP66 and Type 4X ratings, the PROXPAC XL transducer operates reliably in wet, dusty, or corrosive environments common in chemical plants, power generation, and refineries.

5. Direct System Integration
Self-contained design eliminates extension cables and separate Proximitor housings, enabling straightforward connection to monitoring systems for efficient automation workflows.
