Micro-Epsilon - Inductive Displacement and Position Sensors Based on Eddy Currents

Eddy current displacement sensors measure distances, displacements, or positions of any electrically-conductive target. The principle enables non-contact and wear free measurements. The measurement objects can have either ferromagnetic or non-ferromagnetic properties. Due to its immunity to oil, dirt, dust, moisture, interference fields, etc. the eddy current principle is ideally suited to applications in harsh industrial environments.

Micro-Epsilon's eddy current sensors are the only ones with active temperature compensation and field calibration capabilities.
