Foxboro 43AP Pneumatic Controller

The Foxboro 43AP pneumatic controller is a versatile process instrument controller that can be used to control pressure, temperature, flow and level. As with all process controllers, the Foxboro 43AP pneumatic controller continuously detects the difference between a process measurement and its set point. Model 43AP Controller continuously detects the difference between a process measurement and its set point, and produces an output air signal that is a function of this difference and the type of control. The output signal is transmitted to a control valve or other control device. The process measurement, set point, and output signal are indicated on the controller.
