Inducsens is a software for the study of eddy current sensors. 
The software simulates sensor impedance, computes sensor sensitivity and inverts sensor data in order to measure lift-off, thickness, electrical conductivity, magnetic permeability. These parameters can be computed simultaneously.
Sciensoria is also the specialist of custom coils and sensors. 
We have made a rotating field eddy current sensor which can detec external circumferiential notches of 10% tube wall thickness depht.
