Quick Detail

Description

The 330881-28-05-080-00-02 PROXPAC XL Proximity Transducer is a fully integrated proximity monitoring solution designed for industrial automation applications, particularly for fluid-film bearing machines, compressors, and rotating equipment with tight installation constraints. This self-contained transducer combines a 3300 XL 8 mm probe with an integrated Proximitor sensor, eliminating the need for a separate extension cable or external Proximitor housing. Constructed from glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic containing conductive fibers, the PROXPAC XL housing provides superior mechanical strength, electrostatic dissipation, and corrosion resistance compared to traditional steel or aluminum housings. Rated IP66 and Type 4X, it withstands harsh environments with temperatures ranging from -52°C to +100°C (-62°F to +212°F) and offers a linear measurement range of 2 mm (80 mils) with a recommended probe gap of 1.27 mm (50 mils). The assembly accommodates shafts from 50.8 mm to 76.2 mm (2.0–3.0 in) in diameter and supports field wiring of 0.2–1.5 mm² (16–24 AWG) with an output resistance of 50 Ω and supply sensitivity of less than 2 mV change per volt input. By combining probe, sensor, and housing into a single unit, the PROXPAC XL enhances automation system reliability, simplifies installation, and ensures precise, real-time monitoring of vibration, shaft position, and speed.

Applications

Centrifugal Compressor Monitoring
Used in automated systems for continuous radial and axial vibration measurements in compressors operating under tight mechanical constraints, ensuring early fault detection.

Refrigeration and Process Gas Equipment
Provides accurate shaft position and vibration data in refrigeration compressors and gas processing machinery, optimizing automated control loops and predictive maintenance schedules.

Rotating Machinery in Confined Spaces
Ideal for industrial automation where counter bore, side-view, or rear-view restrictions exist, enabling precise measurements without requiring extra cabling or housings.

Integrated Automation Systems
Connects directly to monitoring systems without extension cables, simplifying installation in automated industrial setups while reducing potential electrical noise or connection failures.

High-Humidity and Harsh Environmental Protection
IP66 and Type 4X rating allows automated vibration and position monitoring in chemical plants or offshore facilities, where dust, water, and corrosive atmospheres are present.

Specifications

Competitive Advantage

Fully Integrated Sensor and Housing
Eliminates the need for separate Proximitor sensors and extension cables, reducing installation time and potential points of failure in automated systems.

High Mechanical and Environmental Durability
PPS thermoplastic housing reinforced with glass and conductive fibers resists mechanical impact, corrosion, and electrostatic buildup, ensuring reliability in industrial automation.

Extended Linear Measurement Range
Provides 2 mm (80 mils) linear range with a recommended 1.27 mm gap, offering high-precision automated monitoring on shafts as small as 50.8 mm in diameter.

Simplified Field Wiring
Supports 0.2–1.5 mm² (16–24 AWG) wiring directly to automation monitors, reducing complexity and electrical noise susceptibility in industrial control systems.

Harsh Environment Compatibility
Rated IP66 / Type 4X and operable from -52°C to +100°C (-62°F to +212°F), enabling deployment in automation applications exposed to moisture, dust, or chemical contaminants.
