Abstract
A spray controller accepts a spray pressure input and a pressure control input, and provides a pressure control output. The controller includes an amplifier and pressure transducer, and its pressure control output is the product of the amplifier's gain and the sum of (a) a preset calibration voltage and (b) the product of the pressure transducer's gain and electrical response. The pressure control input controls the gain of the transducer to vary the pressure control output.
