Abstract
Abstract A regulator for industrial process control, including an amplifier and a negative feedback circuit. The regulator is of a proportional, plus integral, plus differential action type which includes RC components in the feedback group. The feedback group includes a plurality of resistors and capacitors having ganged slider arms and adjustment controls for maintaining a high accuracy over a wide range of parameters for the regulator. An input scaling device is provided including a voltage divider network and a potentiometer with the potentiometer connected through the feedback loop or circuit to an input of the amplifier. One input and an output of the amplifier are connected together to serve as a common bus point.
