How It Works

The EPRO PR6423/028-110 utilizes the eddy current principle to measure the distance between the sensor and a metallic object. The system generates an oscillation whose amplitude is dampened by the proximity of the target object. The damping effect is directly proportional to the distance, allowing for precise, non-contact measurements. Additionally, the system comes pre-calibrated, simplifying installation and reducing setup time. Users only need to adjust the gap between the sensor and the object to achieve accurate output.

Key Benefits

Non-contact measurement: This eliminates mechanical wear, reducing maintenance costs and extending sensor lifespan.
Compact and rugged: Designed for industrial environments, it offers high durability in tough conditions.
Pre-calibrated system: The sensor arrives fully calibrated, making installation fast and hassle-free.
High accuracy: Provides precise measurement of displacement, vibration, and other mechanical parameters.
