Quick Detail

Description

The PROXPAC XL Proximity Transducer (model 330881-28-20-040-03-02) is a fully self-contained, high-performance eddy current proximity transducer system engineered for industrial automation applications requiring precise vibration and position monitoring. Integrating a 3300 XL 8 mm probe and Proximitor sensor within a single housing, the PROXPAC XL eliminates the need for separate Proximitor modules or extension cables, providing simplified installation and reliable field wiring connections. With a linear range of 2 mm (80 mils), output resistance of 50 Ω, and supply sensitivity below 2 mV per volt, it delivers highly accurate measurements in both dynamic (vibration) and static (position) monitoring.

The assembly includes a standoff adapter of 200 mm and 40 mm probe penetration, fitting shafts from 50.8 mm to 76.2 mm in diameter, and is equipped with IP66-rated PPS housing reinforced with glass and conductive fibers for electrostatic dissipation and chemical resistance. The housing is lightweight and thermally stable, supporting operation from -52°C to +100°C (-62°F to +212°F), and storage up to +105°C (-62°F to +221°F). Certified to multiple approvals, the PROXPAC XL system offers a modular, robust, and reliable solution for high-precision automation, process control, and industrial machinery monitoring.

Applications

1. Vibration Monitoring in Rotating Machinery
Monitors vibration amplitude in turbines, compressors, and pumps, using a recommended gap of 1.27 mm (50 mils), supporting predictive maintenance and reducing machinery downtime by 25%.

2. Shaft Position Measurement
Provides precise shaft displacement readings for fluid-film bearings and critical shafts, with compatibility for shaft diameters 50.8–76.2 mm, ensuring optimal machinery alignment and performance.

3. Self-Contained Proximity Sensing
The integrated Proximitor sensor eliminates the need for external modules or extension cables, simplifying installation and field wiring in automated systems.

4. Harsh Environment Operation
PPS housing and IP66 rating allow operation in severe industrial environments, including chemical, petrochemical, and offshore applications, protecting the probe from dust, moisture, and electrostatic interference.

5. Automation and Process Control Feedback
Provides accurate real-time output voltage proportional to probe-to-shaft distance, enabling automated speed and Keyphasor measurements in control systems.

Specifications

Competitive Advantage

1. Fully Self-Contained System
Combines the 3300 XL probe and Proximitor sensor in a single housing, reducing installation complexity and eliminating the need for extension cables or separate housings.

2. Durable Thermoplastic Housing
Constructed from PPS reinforced with glass and conductive fibers, the housing offers high chemical resistance, electrostatic dissipation, and Type 4X / IP66 protection, outperforming traditional steel or aluminum housings.

3. High Accuracy and Stability
With a linear range of 2 mm, output resistance of 50 Ω, and supply sensitivity <2 mV per volt, the transducer delivers precise and reliable measurements for both dynamic and static applications.

4. Modular and Versatile Design
Supports shafts from 50.8 mm to 76.2 mm in diameter, standoff adapters of 200 mm, and M20 fittings, enabling seamless integration into a wide range of automated systems and machinery layouts.

5. Simplified Field Wiring and Compliance
Direct connection to monitors reduces wiring complexity, and multiple approvals ensure compliance with CSA, ATEX, IECEx, and industrial standards, providing peace of mind for global industrial deployment.
