LDC systems provide the highest performance when the target is able to provide the largest shift in sensor inductance. To obtain the largest inductance shift requires maximizing the eddy currents on the target subject to the constraints of the system design. Using the techniques discussed here, matching the shape and size of the target to the sensor, using targets with the highest possible conductivity, and ensuring that the target thickness is sufficient to support at least 3 skin depths, will maximize the sensor response to provide the highest possible measurement resolution.
