Multiple Choice

Name three types of Thermocouples.

Explanation:
Thermocouples are temperature sensors made from two dissimilar metals whose junction generates a voltage that depends on temperature. Different metal pairs are grouped into standard types, each with its own usable range and environment. Three commonly used types are J, K, and T. J is iron–constantan, good from about -40 up to 750 C, and works well in oxidizing environments. K, the chromel–alumel pair, covers a wide range (roughly -200 to 1260 C) and is the most widely used due to versatility and durability. T is copper–constantan, excels at lower temperatures and near room temperature with high accuracy. Other groupings listed either mix types that don’t form a standard trio or include high-temperature platinum-based types (which are used in different applications), so they aren’t the typical three-type set. If you’re asked to name three common thermocouple types, J, K, and T are a standard and representative trio.
