Abstract : The patent concerns a fluidic element, such as a laminar proportional amplifier or laminar jet rate sensor, whose null off-set is reduced to substantially zero. A plurality of substantially identical thin laminate plates are stacked between a pair of cover plates. Each of the laminate plates has a passage formed therethrough which is formed by fine blanking that is characterized by formation of a die roll. The die roll has a portion thereof, characterized as a burr, projecting from one side of the plate. A separator plate is positioned between a like number of laminate plates so that the die rolls of each plate on one side of the separator plate face in the opposite direction to that of the die rolls of each of the laminate plates positioned on the other side of the separator plate. The laminate plates and separator plates are all in fluid communication with at least one of the cover plates via aligned supply, control and output conduits.
