Non-contact, inductive displacement sensors from Micro-Epsilon operate according to the eddy current measuring principle. Unlike conventional, inductive displacement sensors, they measure on ferromagnetic and non-ferromagnetic materials providing high accuracy, frequency response and temperature stability. Due to their immunity to oil, dirt, pressure and temperature, these inductive eddy current sensors are primarily used for integration in machines and facilities. |

Performance and universality for industrial use
The new, powerful & inductive eddyNCDT 3060/3070 measuring systems are ideal for fast and precise displacement measurements. Equipped with a compact controller, a sensor and an integrated cable, these systems are factory-calibrated either for ferromagnetic or non-ferromagnetic materials. With numerous sensor models, high speed and smart signal processing, they define a new performance class in inductive displacement measurement.

|
Ideal for integration into plant and machinery
As sensor and controller are temperature-compensated, very high measurement accuracies can be achieved even in fluctuating temperatures. The sensors are designed for ambient temperatures up to a maximum of +200°C and an ambient pressure up to 700 bar.

New benchmark in controller technology
The industrial-grade M12 Ethernet interface enables a modern fieldbus connection. Configurable analog outputs enable to output the measured values as voltage or current. When connecting a PC via the Ethernet interface, a modern web interface can be accessed without any further installation and enables the software setting of sensor and controller.
