Quick Detail

Description

The PROXPAC XL Proximity Transducer (330881-BR-04-70-03-02) is a self-contained, high-precision proximity measurement device engineered for industrial automation and critical machinery monitoring. Featuring a 70 mm probe penetration and a 40 mm standoff adapter, this transducer is designed to deliver accurate shaft vibration and position measurements in compact or recessed installations. The device integrates a 3300 XL Proximitor sensor without approvals, allowing direct connection to monitoring systems while eliminating the need for extension cables or separate Proximitor housings.

The housing is constructed from Polyphenylene Sulfide (PPS) reinforced with glass and conductive fibers, providing high mechanical strength, chemical resistance, and electrostatic dissipation. Rated IP66 and Type 4X, the PROXPAC XL transducer operates reliably in dusty, wet, and harsh industrial environments.

Electrical parameters 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, ensuring stable and precise measurement. It supports a linear range of 2 mm (80 mils) with a recommended gap setting of 1.27 mm (50 mils), suitable for shafts with diameters 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), and storage temperatures extend up to +105°C (+221°F), making it ideal for turbines, pumps, compressors, and motors in automated monitoring systems.

Applications

1. Compact Motor Shaft Monitoring
The 70 mm probe penetration and 40 mm standoff allow accurate vibration and displacement measurements in tight motor enclosures, ensuring early detection of imbalance or misalignment.

2. Turbine Shaft Condition Monitoring
Provides continuous, high-resolution vibration data for turbines, enabling predictive maintenance and minimizing unexpected downtime.

3. Pump and Compressor Automation
Ideal for monitoring shaft displacement in pumps and compressors with limited installation space, supporting automated condition monitoring systems.

4. Harsh Industrial Environments
With IP66 and Type 4X ratings, the transducer reliably operates in dusty, wet, or corrosive environments, such as chemical plants, power generation, and refineries.

5. Direct System Integration
Self-contained design allows direct connection to monitoring equipment, eliminating extension cables and simplifying installation, saving time and reducing maintenance complexity.
