New high-performance eddy current system raises the bar in inductive displacement measurement systems


The eddyNCDT 3060 is a new, powerful eddy current measurement system from Micro-Epsilon that is suitable for high-speed, high-precision displacement measurements in harsh industrial environments. The system comprises a compact controller, a sensor and integrated or non-integrated cable and is factory calibrated for ferrous and non-ferrous materials. With more than 400 compatible sensor models, unique ease of use and smart signal processing, the eddyNCDT 3060 sets new standards in inductive displacement measurement, it is claimed.

In contrast to conventional inductive sensors, displacement sensors that operate on the eddy current measuring
principle stand out due to their high accuracy, bandwidth and temperature stability. Furthermore, this measuring principle enables measurements on ferrous and non-ferrous objects. 
The sensors are also resistant to harsh industrial environments including dirt, oil, high pressures and fluctuating 

The eddyNCDT 3060 is dust-proof and protected against immersion in water for a short period of time (IP67). The sensors are designed for ambient temperatures up to 200°C and ambient pressure up to 20 bar. Active temperature compensation is provided for the sensor and controller, which ensures the high-temperature stability of the complete measurement system.

The eddyNCDT 3060 offers significant performance improvements over its predecessors, the eddyNCDT 3010 and eddyNCDT 3100 systems. The eddyNCDT 3060 is highly adaptable to suit almost any industrial displacement, distance and position measurement application. The DT3061 controller provides enhanced features such as five-point calibration, setting of switching and temperature outputs, as well as storage of multiple characteristic curves. If two or more systems operate next to each other, they do not need to be synchronised: a new frequency separation feature enables these systems to operate in parallel without influencing one another.

Typical applications include the measurement of shaft movement (runout or dilatation), lubrication gap (oil film thickness) and thermal expansion and the monitoring of machines in high-speed, automated production environments. Furthermore, due to the controller’s storage feature for multiple characteristic curves, the system is highly suited to test-bench, research and development (R&D) and laboratory applications.

The industrial-grade M12 Ethernet interface enables modern fieldbus connectivity. Due to the controller’s compact, die cast aluminium design and the fieldbus connection, the measurement system is suitable for integration into a variety of production plant, machines and systems. An easy-to-use web interface simplifies set-up and configuration.

Chris Jones, Managing Director at Micro-Epsilon UK, commented: “The eddyNCDT 3060
offers some very distinct performance advantages, particularly in terms of its unique combination of resolution, linearity and temperature stability. The system is also compact, robust and reliable, to suit harsh industrial conditions, and is equipped with smart signal processing and a fieldbus interface, which simplify integration into machines and automated production systems.”
