What Exactly is Cold Junction Compensation? How Does It Relate …

WebHowever, since the thermocouple measures temperature differentially, the cold-junction temperature must be known in order to determine the actual temperature measured at the hot junction. The simplest case occurs when the cold junction is at 0°C, also known as an ice-bath reference. If T C = 0°C, then V OUT = V H. WebFeb 1, 2024 · Thermocouples measure temperature differentials, not absolute temperatures. Two wires, each made from a different metal, are joined at the tip. This is the measuring junction. At the other end, the wires are connected to a body of a known temperature, called the reference junction.
