Eddy current-based sensors provide precision displacement measurement.
Noncontact measurement systems offer several advantages over contact methods. They can be used on small or fragile parts where contacting the target can cause damage. They have higher accuracy and resolution than traditional contact devices and can be used in closed-loop, highly dynamic environments to provide real-time process information and control without operator intervention. Choosing and deploying the correct measurement technology for a control loop is as critical as the measurement itself.
