Request Information
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.

Additional Information

N/A Performance and universality for industrial use
The eddyNCDT 3070 is a powerful, inductive sensor system based on eddy currents for measuring ranges smaller than 1 mm. The system comprises a compact controller, a sensor and an integrated cable and is factorycalibrated either for ferromagnetic or nonferromagnetic materials.

Ideal for integration into plant and machinery
As sensor and controller are temperaturecompensated, a high measurement accuracy can be achieved even in fluctuating temperatures. The sensors are designed for ambient temperatures up to a maximum of +200 ºC and an ambient pressure up to 700 bar. The compact controller design as well as the sensor robustness make the measuring system ideal for integration into plant and machinery.

New benchmark in controller technology
The industrial-grade M12 Ethernet interface offers a modern fieldbus connection. Configurable analog outputs enable to output the measured values as voltage or current. For multi-system operation, the systems come with a new kind of frequency separation (LF/HF) which enables to operate several sensors next to one another without requiring any synchronization.

Features

Features

 N/A
  • Active temperature compensation for sensor and controller
  • Frequency separation (LF & HF)
  • Industrial Ethernet interface
  • Intuitive web interface
  • Multipoint calibration regardless of the distance (up to 3-point calibration)
  • Scalable measuring range via analog output (teach function)
  • Scalable analog output
  • Switching and temperature outputs
  • 5-point calibration
  • Storage of multiple characteristic curves

Note

N/A For operating several eddyNCDT measuring systems, a new frequency separation (LF/HF) is provided. The frequency separation enables multi-channel operation without mutual influence. This function makes a synchronization cable superfluous.

When connecting a PC via the Ethernet interface, a modern web interface can be accessed without any further installation and enables the parameterization of sensor and controller. The DT3071 controller provides enhanced features such as 5-point calibration, setting of switching and temperature outputs, as well as storage of multiple characteristic curves.
