Quick Detail

Description

The PROXPAC XL Proximity Transducer (330881-28-07-155-03-02) is a self-contained 8 mm proximity probe assembly designed for high-precision shaft vibration and position monitoring in industrial automation. Featuring a 155 mm probe penetration and a 70 mm standoff adapter, this assembly allows reliable installation in challenging machinery layouts while maintaining accurate measurement. Its integrated 3300 XL Proximitor sensor eliminates the need for separate Proximitor housings or extension cables, streamlining field wiring and reducing potential points of failure.

Constructed from Polyphenylene Sulfide (PPS) reinforced with glass and conductive fibers, the PROXPAC XL housing provides exceptional mechanical strength, electrostatic dissipation, and chemical resistance. The assembly is IP66 and Type 4X rated, ensuring operation in wet, dusty, and corrosive industrial environments. It supports a linear range of 2 mm (80 mils) with a recommended gap of 1.27 mm (50 mils) and is suitable for shafts with diameters from 50.8 mm (2.0 in) minimum to 76.2 mm (3.0 in) recommended.

Electrical performance is highly stable with supply sensitivity < 2 mV per volt, output resistance of 50 Ω, and field wiring compatibility with 16–24 AWG cables (0.2–1.5 mm²). Operating reliably over a temperature range of -52°C to +100°C (-62°F to +212°F), the PROXPAC XL transducer ensures accurate, long-term vibration monitoring for turbines, motors, compressors, and other critical rotating machinery in automated industrial processes.

Applications

1. Turbine Shaft Position Monitoring
With a linear range of 2 mm and precise gap setting of 1.27 mm, the PROXPAC XL detects shaft misalignment, vibration, and displacement in high-speed turbines, supporting predictive maintenance programs.

2. Critical Motor Vibration Analysis
The integrated 3300 XL Proximitor sensor continuously monitors motor shaft vibration, enabling early detection of imbalance or bearing faults, reducing unexpected downtime in automation systems.

3. Harsh Environmental Process Plants
The IP66 and Type 4X rated housing withstands dust, moisture, and corrosive chemicals, making it ideal for petrochemical, chemical, and power generation environments.

4. Large Industrial Compressors and Pumps
The 155 mm probe penetration and 70 mm standoff adapter allow installation in deep or recessed housings, enabling accurate monitoring of compressors, pumps, and gearboxes without complex extensions.

5. Compact and Self-Contained Installation
The self-contained design eliminates separate Proximitor housings and reduces field wiring complexity, ensuring reliable installation in confined automation setups and minimizing maintenance errors.
