If conventional inductive sensors reach their limits, eddy-current sensors with highly precise measurement results, extremely small design for easy machine integration, robustness and temperature compensation of electronics and sensors score points.

Particularly where pressure, dirt, oil and high temperatures are present, inductive sensors based on eddy currents from Micro-Epsilon are suitable for all non-contact measurements of displacement, distance, position, oscillation and vibrations. They are characterized by easy operation, high measuring accuracy and an excellent price-performance ratio.

The sensors of the eddyNCDT series are designed for measurements on ferromagnetic as well as non-ferromagnetic objects, such as aluminum and steel, as well as customer-specific adjustments for other materials. Inductive sensors based on eddy currents from Micro-Epsilon offer extremely precise measurements where sub-micron accuracy is required.

Characteristics

  • Non-contact measurement of displacement, distance and position on ferro- and non-ferromagnetic materials
  • Ideal for high speed measurements
  • For harsh industrial environments: dirt, pressure, temperature
  • High linearity, resolution and temperature stability
  • Temperature range -40° C to 200° C and higher
  • Resistant to oil, dust and dirt

What is an inductive displacement sensor?

Inductive displacement sensors (based on eddy-current principle) not only detect the presence of a target (just like inductive proximity switches) but exactly measure the distance from a target. Therefore, eddy current based inductive displacement sensors offer increased linearity, higher frequency response, improved temperature stability and larger measuring ranges than inductive sensors with ferrite core.

Custom inductive sensors for automation and OEMs

Application examples are often found where the standard versions of the inductive sensors and the controller are performing at their limits. For these special tasks, the inductive sensors can be modified accordingly. Changes requested include, for example, modified designs, target calibration, different mounting options, individual cable lengths, modified measuring ranges or sensors with integrated controller.
