Abstract
A fluid quality sensor (20) includes a first electrode (24) that has a fluid passageway (22) that is adapted to be placed in line with at least one fluid conduit (30). A housing (40) is supported on the first electrode (24) in one example by overmolding a portion (48) of the housing onto a portion of the first electrode (24). A second electrode (50) is supported within the fluid passageway (22) and electrically isolated from the first electrode (24). The first electrode (24) and the second electrode (50) operate as a capacitor for making fluid quality determinations.
