Q

The quantity or condition which is measured and controlled is known as the __________.

🔍 Key Concepts

• In automatic control systems, there is usually a difference between what you "adjust" and what you actually want to keep at a certain value. • Think about which term refers to the actual physical thing being measured (like temperature, pressure, level), not the desired value. • Distinguish between the thing you change to get control and the thing you watch to see if control is good.

💭 Think About

• Ask yourself: which option best describes the actual process condition that an instrument or sensor is reading? • Which of these terms would correctly describe, for example, the temperature of a tank that a thermostat is trying to keep steady? • Which choice names the variable that tells you whether the system is at the desired operating condition or not?

✅ Before You Answer

• Be clear on the difference between what you measure and what you adjust in a control loop. • Identify which choice refers to the desired value (the target) rather than the actual measured condition. • Eliminate any terms that usually refer to locations or hardware points rather than the process variable itself.
