🔍 Key Concepts

• Identify what the two sensing lines A and B are likely measuring when connected to different points in a system • Recall what a differential pressure controller is commonly used for in conjunction with a pneumatically actuated control valve • Think about which of the options describes a process variable that can be held steady by comparing two pressures

💭 Think About

• If A and B are connected across two points, what physical quantity is effectively being monitored or controlled: level, flow, or pump discharge head? • Which listed process variable would most logically require a continuous automatic adjustment of a control valve based on changes in differential pressure? • Does any choice describe a signal-conditioning function (like math on a signal) rather than a process condition being maintained?

✅ Before You Answer

• Make sure you can explain to yourself what differential pressure means and how it relates to flow, level, or pump head • Check which answer choice sounds like a control loop objective (the thing being kept constant), not just a description of an internal function of an instrument • Verify that your selected option could realistically use a pneumatically operated valve as the final controlling element in an engineering plant
