Abstract : A fluidic system which has an output related to height above or below a given null altitude is shown. In one embodiment, a fluidic operational amplifier has an input related to the desired null altitude, and further inputs related to static pressure and fixed bias pressure. The inputs are applied through resistors, and feedback is taken through further resistors. Another embodiment is similar to the one described above, but with additional resistors, one inserted between the bias input and its resistor and another between the one resistor and the null input. These resistors compensate for the nonlinear pressure gradient of the earth's atmosphere. (Author)
