ABSTRACT:
For detecting the pressures occurring at a control valve pressure pickup cells are provided and for processing the pressure measuring signals evaluating electronics are provided which together with the pressure pickup cells is arranged on an intermediate plate associated with the control valve. With this arrangement signals may be formed which monitor and control the mode of operation of the consumer governed by the control valve. By arranging the components necessary for the control circuit on the intermediate plate a standardized design is made possible in which the constructional expenditure is greatly reduced.
