High-performance eddy current measuring system for industrial series applications Product Technology

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.

Robust and precise - for industrial series applications at high temperatures.

Precise distance measurements with high resolution up to 40 nm
For fast measurements: Measuring rate 80 kSa/s up to a frequency response of 5 kHz
Robust and compact design with IP67
RS485 interface, scalable analog output (current) and switching output
Fieldbus connection via interface module
Easy configuration via sensorTOOL software
Compatible with numerous sensors offering measuring ranges from 1 ... 80 mm

Extremely high temperature application range of the controller up to 105 °C

The robust DT3020 can also be installed very close to the sensor in hot environments, e.g. in welding applications, in steel rolling processes or in die casting systems. This reduces the cable length between the sensor and controller while minimizing temperature influences on the cable and increasing precision. The measurement signal remains stable and can be transmitted digitally or via a current output over longer distances.

Best temperature compensation worldwide

The eddyNCDT 3020 compensates for temperature fluctuations in the vicinity of the controller between +10 and +105 °C which minimizes the influence on the measurement result. Temperatures on and around the sensor are even compensated up to +180 °C. This provides extremely high precision down to the nanometer range with excellent signal stability.

Configurable & easy to integrate

The eddyNCDT 3020 can be integrated via both digital and analog interfaces as well as via common fieldbuses. The free sensorTOOL is available for convenient configuration. Among other things, this software can be used to scale the analog output, store individual limit values for Condition Monitoring, activate averaging functions for signal smoothing or perform 3-point linearization to optimize measurement accuracy.
