Quick Detail

Description

The PROXPAC XL Proximity Transducer (330881-28-04-145-06-02) is a high-precision industrial automation sensor designed for monitoring rotating machinery shafts in harsh environments. Featuring a 145 mm probe penetration and a 40 mm standoff adapter, it uses an 8 mm 3300 XL probe with multiple approvals to provide accurate displacement measurements for shafts with diameters from 50.8 mm to 76.2 mm. The integrated 3300 XL Proximitor sensor makes this a self-contained proximity measurement system, eliminating the need for extension cables or separate Proximitor housings, while enabling direct connection to monitoring and control systems via 16–24 AWG field wiring.

The transducer housing is constructed from Polyphenylene Sulfide (PPS) thermoplastic, reinforced with glass and conductive fibers, which provides mechanical durability, electrostatic dissipation, and chemical resistance. Rated IP66 and Type 4X, it can operate in extreme industrial environments with temperatures from -52°C to +100°C and storage temperatures up to +105°C. Electrical specifications include <2 mV supply sensitivity, 50 Ω output resistance, a 2 mm linear range, and a 1.27 mm recommended gap, ensuring highly reliable and stable measurements for automation and condition monitoring applications.

Applications

1. Gas and Steam Turbine Shaft Monitoring
The long 145 mm probe allows accurate measurement of shaft vibration and displacement in turbines, supporting predictive maintenance and preventing unplanned downtime.

2. Large Pump Shaft Alignment
Optimizes the alignment of large industrial pumps by continuously monitoring shaft displacement and vibration, improving efficiency and reducing energy waste.

3. Generator Rotor Condition Monitoring
Tracks generator rotor position and motion in real time, helping to prevent rotor damage and extend generator lifespan.

4. Confined or Recessed Installations
The extended probe penetration and compact housing make installation easier in tight spaces or recessed machinery areas without compromising measurement accuracy.

5. Harsh Environment Machinery Monitoring
IP66 and Type 4X ratings ensure the transducer operates reliably in dusty, wet, or chemically aggressive conditions, maintaining long-term industrial performance.

Specifications

Competitive Advantage

1. Self-Contained Design
Integrated 3300 XL Proximitor sensor eliminates the need for separate housings and extension cables, reducing installation time and cost.

2. Extended Probe Penetration
145 mm probe length allows precise measurement in deep or recessed shafts, ensuring comprehensive monitoring in complex industrial setups.

3. Reinforced PPS Housing
Glass and conductive fiber reinforcement enhances mechanical strength, electrostatic dissipation, and corrosion resistance for extended operational life.

4. Environmental Resilience
IP66 and Type 4X ratings allow reliable operation in extreme conditions, including high temperatures, dust, moisture, and chemical exposure.

5. Simplified Field Integration
Supports 3/4-14 NPT threads and 0.2–1.5 mm² wiring, facilitating straightforward integration into existing automation, control, and condition monitoring systems.
