are two different things. This page mainly discusses thermocouple wiring types, not RTDs. If this causes any misunderstanding, we apologize. Thermocouples are widely used because of their broad measurement range and versatility. More importantly, they are relatively low in cost (for types that do not contain precious metals), making them one of the most popular temperature measurement instruments. Today, thermocouples come in many different wiring types. Since each type produces a different output signal, it is important to consider what type of thermocouple the original equipment uses during installation.
