In most instances, Inertia processes are quite uncommon. Give an example of a combined Resistance and Capacitance situation.Describe an application, which according to your understanding of the subject matter, comprises of both Resistance and Capacitance effects.
A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
