Abstract
A compact isothermal connector for a thermocouple temperature measurement system has electrical contacts with thermal mass sufficiently larger than the thermal mass of the corresponding contacts of a corresponding thermocouple connector to provide for improved settling times and measurement accuracy. The contacts are thermally coupled to a multi-layer printed circuit board containing layers of embedded thermally conducting material to achieve sufficient thermal coupling between the contacts. The contacts have sufficient thermal mass to achieve a desired settling time. A temperature sensor is thermally coupled to the printed circuit board and to each electrical contact to sense the temperature of the isothermal connector and provide the temperature information to a temperature measuring instrument to correct for measurement errors from the connector junction voltage.
