Which of the following definitions best describes sensitivity as a characteristic of controller action?

🔍 Key Concepts

• Meaning of sensitivity in control systems and instrumentation • Difference between gain/ratio, offset (steady-state error), manipulated variable, and dead time • How a controller’s output changes when the input (measured variable) changes slightly

💭 Think About

• For each option, ask: Is this talking about a ratio/degree of response, a steady-state error, a description of what the controller moves, or a time delay? • Which phrase sounds like how strongly a controller reacts when the process variable changes a little? • Which option clearly describes how much the output changes for a given small change in input, regardless of time delay or steady-state error?

✅ Before You Answer

• Identify which choice describes a ratio or degree of response between input and output, not time or error. • Eliminate any option that mainly talks about time delay or steady-state difference, since those are separate characteristics. • Verify that the option you choose could be restated as: "how responsive the controller is to changes in the measured variable."

Question 1 of 27070

Which of the following definitions best describes sensitivity as a characteristic of controller action?

The ratio of the output in response to a specified change to the input which caused it.

The steady state difference between the control point and the value of the controlled variable corresponding to the set point.

The variation of the manipulated variable produced by the mode of control.

The time difference between the input change and the output change of the controller.
