Quick Detail

Description

The 330881-16-04-132-03-02 PROXPAC XL Proximity Transducer is a self-contained 8 mm eddy current transducer assembly designed for high-precision vibration and position monitoring in rotating machinery. This assembly integrates a 3300 XL 8 mm probe with an internal Proximitor sensor, eliminating the need for separate extension cables and Proximitor housings. The PROXPAC XL housing is constructed from reinforced Polyphenylene Sulfide (PPS) with glass and conductive fibers, providing superior mechanical strength, electrostatic dissipation, and chemical resistance compared to traditional metal housings. With a linear range of 2 mm (80 mils) and a recommended gap setting of 1.27 mm (50 mils), it ensures accurate measurements of both radial vibration and axial shaft displacement. Designed to accommodate shafts from 50.8 mm (2 in) to 76.2 mm (3 in), the PROXPAC XL 132 mm probe penetration and 40 mm standoff adapter allow installation in tight or restricted spaces. Rated IP66 and Type 4X, the transducer withstands harsh industrial conditions, operating between -52°C and +100°C (-62°F to +212°F) while providing stable, low-noise output through a 50 Ω output resistance and 0.2–1.5 mm² (16–24 AWG) field wiring range. The integrated design simplifies installation, improves reliability, and supports automation, predictive maintenance, and machinery protection systems.
