초록

In a transducer of at least one electrical input signal into two separate magnetic output signals for a pneumatic actuator, a pressure input is connected to a source of pressure and a setting unit sets the pneumatic output signals by use of the electrical input signal. The setting unit provides the two pneumatic output signals separately and reciprocal to each other as a function of the input signal. At least one of the two output signals is connected to a pneumatic amplifier.
