The Emerson EPRO PR6423/010-000-CN CON021 is an 8mm eddy current sensor engineered for high-precision turbomachinery monitoring. It measures radial and axial shaft displacement, eccentricity, position, and speed in turbines, compressors, gearboxes, pumps, and fans.
Key Features
- High-precision linear measurement with 2 mm range ensures reliable turbomachinery monitoring.
- Initial air gap of 0.5 mm provides consistent sensor performance across varying installations.
- ISO-compliant incremental scale factor of 8 V/mm ±5% ensures accurate voltage-to-displacement conversion.
- Minimal deviation from the best-fit straight line (±0.025 mm) maintains sensor accuracy under operational conditions.
- Rugged IP66-rated housing protects against dust, water, and industrial contaminants.
- Wide operating temperature range from -35°C to 200°C supports harsh industrial environments.
- Non-contact measurement eliminates wear, providing long-term reliability and maintenance reduction.
- Compact 8mm sensor tip with PEEK material ensures compatibility with tight installation spaces.
