Real-World Problem Solving

The Challenge: Unplanned downtime from bearing failures costs industries millions annually. Traditional monitoring methods often detect problems too late, after damage has already occurred.

The Solution: This proximity sensor system provides continuous real-time monitoring of shaft position, radial vibration, and axial movement. Early detection of anomalies—such as bearing wear, misalignment, or rotor rubs—enables predictive maintenance strategies that prevent catastrophic failures.

Industry Applications

Power Generation: Monitor turbine-generator sets, feedwater pumps, and induced draft fans. Critical for maintaining grid reliability and avoiding forced outages that can cost $500K+ per day.

Oil & Gas Production: Protect compressor trains, gas turbines, and centrifugal pumps in upstream, midstream, and downstream operations where equipment failure can trigger safety incidents and environmental concerns.

Chemical Processing: Ensure continuous operation of reactor agitators, centrifuges, and process pumps handling corrosive or hazardous materials where reliability is non-negotiable.

Mining & Minerals: Monitor crushers, ball mills, and conveyor drive systems operating 24/7 in abrasive, high-load conditions.

Installation & Integration

The 24653-2-1-25-50-2 mounts directly into standard 5/8-18 threaded probe holders, with the 25-foot armored cable providing routing flexibility to reach monitoring panels or DCS systems. The system interfaces seamlessly with Bently Nevada 3300 and 3500 series monitors, as well as third-party data acquisition systems accepting -2 to -18 VDC inputs.

Factory calibration ensures plug-and-play accuracy, while the rugged construction withstands shock, vibration, and temperature cycling typical of industrial machinery environments.

Reliability Engineering Perspective

Condition-based maintenance programs built around proximity sensor data have demonstrated 30-50% reductions in maintenance costs and 70-90% decreases in unplanned downtime across multiple industries. The 24653-2-1-25-50-2 provides the foundational measurement accuracy required for these programs to succeed.

Product Status: New, factory-sealed unit with complete documentation and manufacturer's warranty.
