ABSTRACT:
A cold junction compensation apparatus utilizes a block of thermally conductive material, such as copper, having a mounting flange extending radially outwardly which is attached to a terminal strip by a machine screw to maintain the screw temperature substantially at the temperature of the block of thermally conductive material. The temperature of the block is sensed by means of a temperature sensor inserted into a hole extending through the block. The sensor is supported on a printed circuit board and is inserted through the hole in the block during assembly of an apparatus using the cold junction temperature compensation. The block is covered by an exterior insulating sleeve to prevent electrical shorts and rapid temperature changes in the block.
