  • Temperature reference junction for a multichannel temperature sensing system
    Patent number: 5046858
    Abstract: A multi-channel remote-temperature-sensing system has a reference temperature assembly for the reference junctions of a plurality of temperature sensors for determining temperatures at remote points. The assembly comprises an array of components each adapted to make thermal contact with a reference junction of a remote-temperature-sensing thermocouple, an absolute reference thermometer situated within the array for measuring an absolute reference temperature, a thermocouple for sensing a temperature difference between the absolute reference thermometer and a component of the array, and data processing means for calculating the temperature of the component of the array from the absolute reference temperature and the temperature difference.
