The return signal from a valve as sensed by an automatic flow controller that is proportional to the actual valve position is referred to as:

🔍 Key Concepts

• Automatic control systems: how a controller, final control element (valve), and sensor/transmitter work together • The meaning of gain, bias, feedback, and error in a basic control loop • The idea of a signal that represents the actual valve position, not the desired position

💭 Think About

• In a control loop, what do we call any signal that goes back from the controlled device or process to influence the controller’s action? • Which of these terms describes a signal that represents the difference between setpoint and actual value, and which describes the actual value itself? • Think about which term is usually associated with changing the slope/sensitivity of a controller, and which term is related to the offset or starting point of a signal.

✅ Before You Answer

• Identify which term is defined as information returned to the controller about the current state of the system • Separate in your mind: which option refers to a difference between two values vs. a measurement of actual position • Verify which term is commonly used for adjusting the sensitivity (slope) of a controller’s response to its input
