Key Features & Benefits

Precision Monitoring: Delivers micron-level accuracy for detecting shaft position, vibration, and axial displacement in rotating machinery, enabling early fault detection before catastrophic failure occurs.

DCS Integration Ready: Seamlessly interfaces with Emerson Ovation, DeltaV, and third-party distributed control systems through industry-standard signal protocols, reducing commissioning time by up to 40%.

Harsh Environment Durability: Engineered with corrosion-resistant materials and hermetic sealing to withstand extreme temperatures, moisture, chemical exposure, and electromagnetic interference common in industrial settings.

Long-Term Stability: Advanced temperature compensation and drift-free electronics ensure measurement consistency over years of continuous operation, minimizing recalibration requirements.

Application Scenarios

Steam & Gas Turbines: Monitor thrust bearing wear and axial position in power generation turbines, preventing unplanned shutdowns that cost thousands per hour.

Compressor Systems: Track rotor position in centrifugal and axial compressors used in petrochemical processing, ensuring optimal clearance and preventing surge conditions.

Pump Monitoring: Detect bearing degradation and shaft misalignment in critical process pumps before mechanical failure leads to environmental incidents or production losses.

Motor-Generator Sets: Provide continuous surveillance of air gap and rotor eccentricity in large synchronous machines, supporting condition-based maintenance strategies.

Solution Integration

The PR9350/02-S3 forms part of a comprehensive machinery protection ecosystem when paired with Emerson EPRO monitoring modules and analysis software. Deploy alongside vibration transmitters, temperature sensors, and speed monitors to create a multi-parameter protection layer that meets API 670 and ISO 20816 standards.

Installation is straightforward with standard M18 threading and adjustable mounting brackets. The sensor's self-diagnostic capabilities communicate health status to your SCADA system, enabling predictive replacement before sensor failure impacts process safety.
