The familiar thermocouple (TC) is probably the oldest species of electronic temperature sensor extant. TCs consist merely of two dissimilar conductors joined at the temperature measuring point. They're simple to fabricate and look (at first glance) equally easy to use.

Unlike other temperature sensors, TCs are intrinsic voltage sources and therefore require no excitation or power supply. They can be miniaturized to fit inside needle points and made to function in temperatures ranging from cryogenic to incandescent. So it's easy to understand the durable popularity of these ...
