<p>A pneumatic controller is disclosed having an automatic switching of its time behavior as a function of the control pressure by means of a relay being arranged in the integrating feedback path and being actuated by the control pressure. According to the invention, the relay connects the integrating feedback path to the atmospheric pressure when the control pressure attains an upper limit and/or to the supply pressure when the control pressure attains a lower limit.</p> |
