Distance and weight measurement using inductive sensing reference design

The Distance and Weight Measurement Using Inductive Sensing Reference Design is a sub-system design which converts a distance measurement to a weight measurement. This design is intended as a reference design for building automation and weigh scale applications. In mechanical systems, there are many situations that require precise and accurate measurements of distance. One such scenario is the conversion of a distance measurement to a weight measurement, through the use of springs with well-known characteristics. This reference design enables weight and distance measurements to be incorporated into end systems, without the use of expensive magnets or other sensing materials.
