thermocouple

Bimetallic heat detector

A thermocouple is a device that measures temperature by generating a small electrical voltage where two different metal wires join.

The voltage changes predictably with temperature, making thermocouples useful in industrial settings, scientific instruments, and appliances: The furnace uses a thermocouple to monitor heat levels.
