Distance and Weight Measurement Using Inductive Sensing Reference Design

Description

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.
