Conduction Error in Thermocouples Embedded in Low Conductivity Material

Thermocouples are generally used as devices to determine the internal temperature of any material. The purpose of the temperature measuring device is to measure the temperature which would exist at some known location if the device were not present. The thermocouples are embedded in the material in order to study the temperature-time history of the point of location. The presence of the thermocouple induces error in the temperature measured. This error becomes significant if heat is conducted into or away from the point of measurement by the sensor itself, or if the sensor insulates the point. This would result from much larger thermal conductivity of the thermocouple assembly than the surrounding material. This error in the temperature measurement will be called "conduction error."
