Isothermal panel assembly for terminating a plurality of thermocouple leads

摘要

A panel assembly for terminating a plurality of thermocouple leads is disclosed. The panel assembly has sufficient mass that it can stabilize at the temperature of the surrounding air. All thermocouple termination posts are of a common metal such as copper so that all subsequent leads can be copper and thereby reduce termination errors due to subsequent thermoelectric effects. A temperature measuring device is embedded in the mass of the panel assembly for measuring the temperature of the termination points of the thermocouple leads. Recorder jacks are provided so that an external recorder may record the outputs of the thermocouple.
