Quick Detail

Description

The PROXPAC XL Proximity Transducer (330881-28-04-85-03-02) is an advanced industrial automation sensor designed for high-precision shaft monitoring, vibration detection, and predictive maintenance in harsh operating environments. Equipped with an 85 mm probe penetration, a 40 mm standoff adapter, and an 8 mm 3300 XL probe with multiple approvals, it provides accurate displacement measurement for shafts ranging from 50.8 mm to 76.2 mm in diameter. The integrated 3300 XL Proximitor sensor makes this transducer a self-contained system, eliminating the need for extension cables or separate Proximitor housings, and allowing direct connection to condition monitoring systems through 16–24 AWG field wiring.

The housing is manufactured from Polyphenylene Sulfide (PPS) thermoplastic reinforced with glass and conductive fibers, ensuring mechanical strength, electrostatic charge dissipation, and corrosion resistance. Rated IP66 and Type 4X, it reliably operates in extreme temperatures from -52°C to +100°C and storage temperatures up to +105°C, providing consistent performance in dusty, wet, and chemically aggressive industrial environments. Electrical characteristics include <2 mV supply sensitivity, 50 Ω output resistance, and a 2 mm linear range with a recommended 1.27 mm gap, delivering precise and stable measurements for automated industrial systems.

Applications

1. Industrial Turbine Shaft Monitoring
The 85 mm probe length supports precise vibration and displacement monitoring on turbine shafts, enabling early detection of misalignment or imbalance.

2. Centrifugal Pump Performance Optimization
Monitors shaft movement and vibration to optimize pump operation, reducing energy consumption and preventing mechanical failure.

3. Generator and Motor Condition Monitoring
Provides continuous shaft monitoring for rotating electrical machinery, improving reliability and extending equipment lifespan.

4. Confined Space Equipment Measurement
Compact standoff adapter and integrated sensor design allow accurate measurement in tight or hard-to-access installation areas.

5. Harsh Environment Operations
IP66 and Type 4X housing ensure reliable operation in environments with dust, water, high temperature, and corrosive substances.

Specifications

Competitive Advantage

1. Fully Integrated Sensor
The 3300 XL Proximitor sensor is built directly into the housing, eliminating extension cables and separate housings, simplifying installation.

2. Reinforced PPS Housing
Glass and conductive fiber reinforcement enhances durability, electrostatic discharge resistance, and chemical protection for extended operational life.

3. Extended Probe Penetration
85 mm probe length accommodates recessed or large-diameter shafts, ensuring accurate measurement for diverse industrial applications.

4. High Environmental Resistance
IP66 and Type 4X ratings allow reliable operation under extreme conditions, including dust, water, and temperature variations.

5. Simplified Field Wiring and Mounting
Supports 3/4-14 NPT threads and 0.2–1.5 mm² wiring, facilitating easy integration into existing automation and monitoring systems.
