🔍 Key Concepts

• Differences between thermocouples, RTDs (resistance temperature detectors), thermistors, and bimetallic devices • Meaning of a negative temperature coefficient of resistance (resistance decreases as temperature increases) • Typical materials used in each type of temperature sensor (metals vs metallic oxides)

💭 Think About

• Which of these devices is specifically known for using metallic oxides instead of pure metals or metal alloys? • Which sensor type is commonly described as having either a negative or positive temperature coefficient, used in electronic circuits? • Which devices on the list work mainly by mechanical bending or by generating a voltage from temperature difference, rather than by a simple resistance change?

✅ Before You Answer

• Identify which option is usually made from metallic oxides, not metal wires or strips • Confirm which sensor type is commonly described as having a negative temperature coefficient (NTC) • Eliminate the options that primarily rely on mechanical movement or generated voltage instead of resistance change in metallic oxides
