Quick Detail

Description

The PROXPAC XL Proximity Transducer (330881-28-05-090-00-02) is a high-precision, self-contained proximity sensor assembly designed for industrial automation and rotating machinery condition monitoring. Featuring a 90 mm probe penetration and a 50 mm standoff adapter, this transducer ensures accurate shaft vibration and displacement measurements in tight or recessed mounting locations. It incorporates a 3300 XL 8 mm Proximitor sensor with multiple approvals, delivering stable output and precise measurements while removing the need for separate Proximitor housings or extension cables.

The assembly is built from Polyphenylene Sulfide (PPS) reinforced with glass and conductive fibers, offering high mechanical strength, chemical resistance, and electrostatic charge dissipation. Rated IP66 and Type 4X, the PROXPAC XL housing withstands dust, water, and harsh industrial environments. 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 with diameters from 50.8 mm (2.0 in) minimum to 76.2 mm (3.0 in) recommended.

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 reliable and low-noise performance. Operating temperatures range from -52°C to +100°C (-62°F to +212°F), making this transducer ideal for turbines, motors, compressors, and other critical rotating equipment, enabling automated condition monitoring and predictive maintenance to reduce operational downtime.

Applications

1. Turbine Shaft Displacement Monitoring
The 90 mm probe penetration allows precise detection of turbine shaft displacement, supporting condition monitoring programs for early vibration detection.

2. Electric Motor and Generator Diagnostics
Integrated 3300 XL sensor continuously measures shaft vibration and position, enabling automated performance analysis and preventive maintenance.

3. Severe Industrial Environment Monitoring
With IP66 and Type 4X ratings, this transducer operates reliably in dusty, wet, or corrosive environments common in petrochemical, power generation, and manufacturing plants.

4. Pump and Compressor Vibration Tracking
The 50 mm standoff adapter ensures proper installation in compact pump or compressor housings, providing accurate vibration and shaft motion data for condition-based maintenance.

5. Simplified System Integration
The self-contained assembly eliminates the need for separate Proximitor housings or extension cables, reducing installation complexity and supporting direct connection to automated monitoring systems.
