🎯 Core Functionality

The proximitor serves as the critical interface between proximity probes and monitoring systems. It provides regulated excitation voltage to the probe, receives the probe's variable impedance signal, and converts it into a standardized DC voltage output that's proportional to the gap between probe tip and target surface.

This conditioned signal enables precise measurement of shaft vibration, axial position, differential expansion, and eccentricity—parameters essential for protecting turbines, compressors, pumps, and generators from catastrophic failures.

⚡ Performance Advantages

✓ Wide Bandwidth: Captures both slow-roll data and high-frequency bearing defects in single channel
✓ Low Noise Floor: Advanced filtering eliminates electrical interference from VFDs and welders
✓ Buffered Output: Drives multiple loads simultaneously without signal degradation
✓ Temperature Stable: Maintains calibration accuracy across industrial temperature extremes
✓ Diagnostic LEDs: Instant visual indication of power, OK status, and fault conditions

🏭 Industry Applications

Power Generation: Monitor bearing vibration and rotor position in steam turbines, gas turbines, and generator sets where unplanned outages cost millions per day in lost revenue and grid penalties.

Oil & Gas: Track compressor shaft dynamics in pipeline stations and LNG facilities where equipment reliability directly impacts production capacity and safety performance.

Chemical Processing: Surveil pump and agitator shaft motion in continuous process plants where machinery failures trigger emergency shutdowns and environmental incidents.

Manufacturing: Measure spindle runout and bearing condition in high-speed production equipment where precision and uptime determine profitability.

💡 System Architecture

The 3300/47-09-03-01-00 integrates seamlessly into comprehensive monitoring systems. Connect the proximitor output to 3500 rack monitors, standalone trip modules, PLC analog inputs, or data acquisition systems. The module's low output impedance allows daisy-chaining to multiple destinations without signal splitters.

Pair with any Bently Nevada 8mm proximity probe and appropriate extension cables to create a complete measurement channel. The system maintains factory calibration when total cable length stays within specified limits (consult documentation for your specific probe model).
