Transducer 10, which transforms an electrical signal to a pneumatic signal and comprises an orifice 12, which receives an incoming pneumatic source and which emits a gas flow 20. The receiver 16, situated at a distance from the orifice 12, is located so that it receives at least a part of the gas flow 20. The part received forms a pneumatic output signal (Pout). An electrical input signal (Iin) controls the position of the control element 14 in relation to the gas flow 20, so that the control element aerodynamically diverts the gas flow emitted from the orifice 12. The aerodynamic diversion influences that part of the gas flow 20 received by the receiver 16 so that it varies as a known function of the electrical input signal, by means of which a pneumatic signal is generated, varying as a function of the electrical input signal. <IMAGE> |
