Eddy Current Displacement Sensors and Their Applications
Eddy current displacement sensors (ECDS) represent a mature, yet continuously evolving, non-contact measurement technology that utilises the principles of electromagnetic induction.
From non-contact displacement measurement to defect detection in materials, these sensors play a crucial role in quality control and process monitoring. In this article, we'll explore what eddy current sensors are, their operating principle, types, applications, and provide a simple eddy current sensor diagram for better understanding.
