Quick Detail

Description

The PROXPAC XL Proximity Transducer (330881-28-04-70-03-02) is a high-precision automation sensor engineered for industrial machinery monitoring and rotating shaft diagnostics. Featuring a 70 mm probe penetration with a 40 mm standoff adapter and a 3300 XL 8 mm probe with multiple approvals, it delivers accurate shaft displacement and vibration measurement critical for predictive maintenance, process optimization, and operational reliability. The self-contained PROXPAC XL design integrates a 3300 XL Proximitor sensor directly in the housing, eliminating the need for extension cables or separate Proximitor housings, and allows direct connection to monitoring systems through 16–24 AWG field wiring.

Constructed from reinforced Polyphenylene Sulfide (PPS) thermoplastic with glass and conductive fibers, the housing provides enhanced mechanical strength, electrostatic discharge dissipation, and corrosion resistance. Rated IP66 and Type 4X, it withstands harsh industrial environments, including dust, moisture, and chemical exposure. Electrical specifications include <2 mV change in output per volt of input variation, 50 Ω output resistance, and a 2 mm linear range with a recommended 1.27 mm gap. Compatible with shaft diameters from 50.8 mm to 76.2 mm, the transducer operates reliably in temperatures from -52°C to +100°C, with storage up to +105°C, making it ideal for turbines, compressors, pumps, and motor-driven equipment.

Applications

1. Turbine Shaft Displacement Monitoring
The 70 mm probe accurately measures turbine shaft position, enabling early detection of misalignment, imbalance, and vibration for predictive maintenance.

2. Industrial Motor and Generator Health
Real-time monitoring of motors and generators ensures operational reliability, detecting abnormal vibrations in shafts from 50.8 mm to 76.2 mm.

3. Pump and Compressor Performance Optimization
Provides precise vibration and displacement data to optimize pump and compressor efficiency and prevent mechanical failures.

4. Automated Industrial System Integration
Self-contained sensor and simplified wiring allow fast deployment and direct integration into industrial automation and control networks.

5. Harsh Environment Reliability
IP66 and Type 4X rating ensures consistent performance in high-dust, high-moisture, and chemically aggressive industrial conditions.

Specifications
