High-Precision Inductive Displacement Sensor for Turbomachinery Monitoring
The Emerson EPRO PR9350/02-S2 is an industrial-grade inductive proximity sensor engineered for non-contact displacement measurement in rotating machinery applications. Designed to deliver exceptional accuracy and long-term stability, this sensor is the preferred choice for condition monitoring in critical turbomachinery installations across power generation, oil & gas, and process industries.
Technical Specifications
- Measurement Range: 0-2mm (0.079 inches)
- Linearity: ±1% FSO (Full Scale Output)
- Operating Temperature: -40°C to +125°C (-40°F to +257°F)
- Output Signal: -8V to -2V DC (proportional to gap)
- Frequency Response: DC to 10 kHz (-3dB)
- Thread Size: M8 x 1.0mm
- Cable Length: Standard 5m extension available
- Protection Rating: IP67 (dust-tight and waterproof)
Application Scenarios
This sensor excels in demanding environments where precise shaft displacement monitoring is critical:
- Steam & Gas Turbines: Real-time axial and radial displacement tracking to prevent catastrophic bearing failures
- Compressor Monitoring: Continuous surveillance of rotor position in centrifugal and axial compressors
- Generator Protection: Early detection of abnormal shaft movement in large rotating generators
- Pump Condition Monitoring: Vibration and displacement analysis in high-speed pumps
Integrated Solutions
The PR9350/02-S2 seamlessly integrates with Emerson Ovation DCS and AMS Machinery Manager platforms, enabling:
- Automated alarm generation when displacement exceeds safe thresholds
- Trend analysis and predictive maintenance scheduling
- Direct compatibility with EPRO CON021 and PR6423 monitor modules
- Support for API 670 machinery protection standards
Why Choose PR9350/02-S2?
Unlike capacitive or optical sensors, the inductive design ensures immunity to oil mist, dust, and temperature fluctuations common in industrial environments. The rugged stainless steel housing withstands harsh chemical exposure, while the hermetically sealed electronics guarantee decades of maintenance-free operation. Factory calibration certificates ensure measurement traceability to international standards.
