Abstract
A capacitive sensor assembly for detecting relative movement or position between objects, such as liquid level in a tank or reservoir, movement of one machine component with respect to another, and so on, includes one or more antenna probes connected to an integrated chip normally associated with touch-screen displays. Each antenna probe operates independently and may be formed as insulated conductive wires or conductive traces between layers of a stiff or flexible substrate, such as a PCB, with the substrate material serving as the insulating layers. Each antenna probe has a different length representing different measurement positions or locations between the objects being measured to provide dynamic calibration of the measurement under changing environmental conditions.
