The eddyNCDT 3020 is a compact and powerful inductive measuring system (eddy current) for fast and precise displacement, distance and position measurements in industrial applications. Flexible in terms of connectivity and easy to configure, it can be used for numerous measurement tasks in industry and machine building.
The sensor system is designed for series and OEM applications and delivers precise and stable measurement results even under harsh conditions - up to max. 200 °C ambient temperature. The robust controller can be combined with a wide variety of sensors and is factory-adapted to ferromagnetic or non-ferromagnetic materials.
