Abstract
A uniform temperature reference block for connection with the cold reference wires of a plurality of thermocouples employing a corresponding plurality of screw terminal modular connectors each provided with an insulated termination cavity containing a terminal conductor compressable, upon tightening the screw, against the thermocouple input wire and, in turn, the wire against an adjacent electrically insulated but thermally conductive projection of a thermal bridging bar, preferably of anodized aluminum, within the termination cavity, to establish electrical termination connection of the thermocouple wire with thermal coupling along the block.
