ABSTRACT OF THE DISCLOSURE An electric signal to pneumatic signal transducer 10 comprises a nozzle 12 that accepts an input pneumatic supply and expels a gas stream 20. A receiver 16 that is spaced from the nozzle is positioned to recover at least a portion of the gas stream. The recovered portion constitutes a pneumatic output signal. The position of a deflector 14 relative to the gas stream is controlled by an electric input signal to aerodynamically deflect the gas stream expelled from the nozzle. The aerodynamic deflection affects the magnitude of the portion of the gas stream recovered by the receiver in a manner having a known relationship to the electric input signal, thereby generating a pneumatic output signal responsive to the electric input signal.
