Draw a loop diagram (using the bubbles and other symbols shown to you) of a control system, which works as follows:

1.     A pneumatic valve is out in the field, used to control a PRESSURE application;

2.     The controller is in a LOCAL control panel, and is not accessible to the operator.  Please note  that this controller also has the capacity to display the PRESSURE PV;
