🔍 Key Concepts

• Thermocouple polarity and voltage: how the output voltage changes with temperature at the measuring junctions • Series-aiding vs. series-opposing connections: what happens to voltages when they add versus when they subtract • Using two sensors to measure a difference rather than an absolute value

💭 Think About

• Think about what each thermocouple produces: is its output proportional to its own temperature or a reference? • If you want the instrument to see the difference between two temperatures, should the voltages from the two thermocouples add together or cancel each other out? • Imagine one location is hotter than the other: in each wiring option, what happens to the total voltage seen by the meter?

✅ Before You Answer

• Review how thermocouple output polarity works when one junction is hotter than the reference junction • Check which wiring method causes voltages to add and which causes them to subtract • Eliminate any choice that claims it is impossible to measure a temperature difference with two thermocouples, based on your basic understanding of sensors
