Many applications require the use of maintenance-free, single-version, non-electrical, movement-free, intrinsically safe devices, devices able to be implemented with different fluids. Fluidic elements satisfy these requisites. Fluidic proportional amplifiers are of particular interest, because they proportionally amplify an output signal compared to the control signal. We developed a highgain proportional amplifier that amplifies signals optimally at the output even with very low command signals. This broads the range of applications for these devices as control systems. Our results demonstrate that our element has good operating characteristics.
