I/O CONNECTOR INCORPORATING A COLD JUNCTION

摘要

A thermocouple connection device for terminating a cold junction of a thermocouple includes a housing configured to receive a substrate including an isothermal block positioned within a hollow interior space. Each of a plurality of connection elements include a first portion coupled to a second portion at a cold junction. The cold junction is positioned within the isothermal block such that the first portion and the second portion extend through opposite ends of the substrate. The first portions and the second portions of the connection elements extend through the housing in opposite directions to each other. A first distal end of the first portion is connectable to a control device, and a second distal end of the second portion is connectable to a hot junction. A resistance temperature device (RTD) is coupled to the isothermal block adjacent the cold junctions for measuring a temperature in proximity of the cold junctions.
