Answer Posted / ferdinand
Split range control in process operations point of view, generally used in pressure control, flow and level control also in controlling temperature.
for example a split range control application for pressure control. the input coming from pressure transmitter is processed by the pressure controller then relays the output split between the two control valves to modulate the pressure of a certain vessel.
There are many variations of split controller, like for expmaple valve A at 49% start to modulates the opening to 0% full open while the other valve starts to modulate at 51% opening to 100% full open. for this example both valve are close at 50%. at 50% it means the set point and the process value are the same so the valves are both close. on this particular example, one valve normally supplies the pressure while the other releases it normally goes to the flare system or other systems that serves the purpose.
The accuracy of the control is due to incorporations of PID. the proportional, Integral and the derivatives that in laymans terms it considers the present, the future and the past in predicting the relays in order to control.
