Comparison of Control Loops – Open, Closed, Cascade, Feedforward, Ratio
Control loops are the building blocks of control systems and come in various configurations such as open, closed, cascade, feedforward, ratio.

Examine these pressure and level control loops (transmitter-controller-valve systems) for an industrial boiler, controlling both water level and steam pressure:
This pictorial diagram shows the wiring connections for a simple pressure control loop, where a loop- powered 4-20 mA pressure
In electrical signalling an analog current loop is used where a device must be monitored or controlled remotely over a
Before we begin our discussion on process control, we must define a few key terms. First, we have what is
The simplest form of 4-20 mA current loop is the type used to represent the output of a process controller,
A control loop is a process management system designed to maintain a process variable at a desired set point. Each
This article provides list of Distributed Control System Interview Questions and Field Instrumentation Questions which are faced in a interview.
Instrumentation is the science of automated measurement and control. Applications of this science abound in modern research, industry, and everyday
