Technical Specifications

Detailed Description

The EPRO PR6423/022-110 eddy current sensor is engineered to measure key mechanical parameters in turbomachinery such as displacement, vibration, and eccentricity. This sensor employs the eddy current principle, offering precise measurements without physical contact. It can monitor critical components, including clearances between rotating and stator parts, thrust bearing wear, and oil film thickness.

Thanks to its non-contact measurement principle, the EPRO PR6423/022-110 offers enhanced durability, even in high-vibration and high-temperature environments. It measures dynamic motion, shaft eccentricity, and other important parameters, helping optimize the performance and reliability of turbomachinery.

This sensor operates in combination with a signal converter, forming an oscillator circuit. The amplitude of oscillation decreases as a metallic object moves closer to the sensor. The sensor is factory-calibrated, so you only need to adjust the air gap between the sensor and the target object for optimal performance. No on-site calibration is required, simplifying the installation process.

With an IP66 protection class, the EPRO PR6423/022-110 is highly resistant to dust and water, making it suitable for challenging environments. It can operate across a wide temperature range, from -35°C to 180°C (-31°F to 356°F), ensuring reliable performance in extreme conditions.

Applications

• Turbomachinery Monitoring: Ideal for measuring displacement, vibration, and eccentricity in gas turbines, steam turbines, compressors, and pumps.
• Clearance and Shaft Monitoring: Accurately measures clearances and monitors axial and radial shaft movements.
• Bearing and Oil Film Measurement: Tracks thrust bearing wear and measures oil film thickness.
• Differential Expansion and Valve Positioning: Monitors differential expansions, housing expansions, and valve positions.
