Short Description:

Type B thermocouple wire is a type of temperature sensor that's part of the thermocouple family, known for its high temperature accuracy and stability. It's composed of two different metal wires joined together at one end, typically made of platinum-rhodium alloys. In the case of Type B thermocouples, one wire is composed of 70% platinum and 30% rhodium (Pt70Rh30), while the other wire is made of 94% platinum and 6% rhodium (Pt94Rh6).

Type B thermocouples are designed to measure high temperatures, ranging from 0°C to 1820°C (32°F to 3308°F). They're commonly used in applications such as industrial furnaces, kilns, and high-temperature laboratory experiments. Due to the precise combination of materials used, Type B thermocouples offer excellent stability and accuracy, particularly at high temperatures.

These thermocouples are preferred in situations where very high accuracy is required, though they are more costly than other types of thermocouples. Their accuracy and stability make them suitable for demanding applications in industries such as aerospace, automotive, and metallurgy.
