Description
PR6423/001-000+CON021 Basic Information
Manufacturer: Emerson Epro
Product Type: Eddy Current Displacement Sensor (Proximitor Series)
Model Suffix Explanation:
“-101”: Indicates 10m factory-standard shielded cable
“-CN”: Denotes China-region compatibility, including localized certifications and technical support
Product Positioning: Core measuring component for rotating machinery condition monitoring systems, specialized in non-contact displacement measurement.
Working Principle
Operates based on the eddy current (electromagnetic induction) principle: The internal coil of the sensor generates a high-frequency alternating magnetic field. When approaching a conductive material (e.g., a rotating shaft), induced eddy currents are produced on the material’s surface. These eddy currents react back to alter the coil’s impedance; the distance between the sensor and the measured object is accurately calculated by detecting this impedance change.
Core Functions
Non-contact measurement of radial and axial shaft displacement (static range: ±1.0mm)
Monitoring of shaft vibration (dynamic range: 0–500μm; optimal measurement range: 50–500μm)
Detection of shaft eccentricity and rotational speed
Output of analog voltage signals proportional to displacement (sensitivity: 8V/mm)

System Integration
Must be used with a matching preamplifier to form a complete measurement system:
Recommended Preamplifier Models: CON011, CON021, or CON031 series
Connection Methods: Lemo connector (for CON011/CON021) or screw terminals (for CON031/CON041)
Signal Conversion: After processing by the preamplifier, standard signals (4–20mA DC or ±10V DC) are output for integration with DCS/PLC systems.
Application Fields
Specifically designed for critical turbomachinery and rotating equipment:
Steam/gas/hydraulic turbines
Compressors and pumps
Gearboxes and fans
Nuclear power plant equipment (special variants offer radiation resistance)
Other industrial rotating machinery requiring high-precision condition monitoring
Product Advantages
Non-Contact Operation: No wear on the probe or measured object, suitable for long-term continuous monitoring.
High Precision: Micron-level resolution meets the requirements of precision equipment monitoring.
Strong Anti-Interference: Unaffected by oil, moisture, or other media, ideal for harsh industrial environments.
Rapid Response: Compatible with high-speed rotating machinery (maximum shaft peripheral speed: ≤2500m/s).
Reliability: Excellent long-term stability, designed for 24/7 continuous operation.
