Abstract

A non-contact sensor system is provided that comprises a first sensor element disposed on an outside surface of a chamber. The chamber comprises an inside surface configured to receive a piston, and the piston is configured to move a value X within the chamber without physically contacting the first sensor element. The non-contact sensor system further comprises a second sensor element disposed on the piston and separated from the first sensor element by a wall of the chamber. The first sensor element and the second sensor element are operatively coupled to facilitate sensing the value X. The non-contact sensor system may be configured to sense velocity, acceleration, volume, and other values.
