Quick Detail

Description

The 330881-28-09-080-03-02 PROXPAC XL Proximity Transducer is a fully integrated, high-performance transducer system designed for industrial automation and advanced condition monitoring applications. This assembly combines a 3300 XL 8 mm proximity probe with an onboard Proximitor sensor, eliminating the need for separate extension cables or external Proximitor housings. With a 90 mm standoff adapter and 80 mm probe penetration, the PROXPAC XL transducer provides precise radial vibration and axial position measurements on fluid-film bearing machinery. The robust PPS (Polyphenylene Sulfide) thermoplastic housing reinforced with glass and conductive fibers offers exceptional chemical and mechanical resistance while dissipating electrostatic charges. Rated to IP66 and Type 4X standards, it ensures protection against dust, moisture, and harsh environmental conditions. Operating reliably between -52°C and +100°C (-62°F to +212°F), the system accommodates shafts with a minimum diameter of 50.8 mm (2 in) and recommended diameter of 76.2 mm (3 in). Its linear range of 2 mm (80 mils), recommended gap of 1.27 mm (50 mils), output resistance of 50 Ω, and supply sensitivity below 2 mV per volt ensure accurate, stable signals for industrial monitoring and automation systems. Field wiring supports 0.2 to 1.5 mm² (16–24 AWG), enabling flexible integration into existing monitoring networks. The PROXPAC XL’s self-contained design streamlines installation, reduces cabling errors, and enhances measurement reliability in demanding industrial environments.

Applications

Fluid-Film Bearing Vibration Monitoring

Provides high-resolution radial vibration measurement for fluid-film bearings, detecting deviations as small as 0.05 mm to prevent early machinery failure.

Axial Position Measurement in Compressors

Monitors thrust positions on shafts, with recommended gap settings of 1.27 mm (50 mils), ensuring accurate axial displacement control for centrifugal and process gas compressors.

Self-Contained Proximity Transducer Integration

Eliminates extension cables and separate Proximitor housings, allowing compact installation in tight machinery spaces while reducing wiring complexity and signal loss.

Harsh Environment Applications

Rated IP66 and Type 4X, the PROXPAC XL withstands dust, moisture, and corrosive industrial atmospheres, supporting reliable automation system performance in chemical or refinery plants.

Shaft Diameter Compatibility

Designed for shafts from 50.8 mm (2 in) to 76.2 mm (3 in), enabling application across small to medium rotating machinery while maintaining linear range of 2 mm for precision measurements.

Specifications
