Abstract:
A setting-free, temperature-measuring module apparatus for a first plurality of resistive temperature devices (RTDs) connected thereto, comprising:means for measuring the resistance of said first plurality of RTDs present at selected sites where temperature is to be monitored; means for storing a plurality of resistance/temperature maps for a selected number of different types of RTDs, including temperature maps for at least those types comprising said first plurality of RTDs; processing means for determining a plurality of different temperature values for each resistance value measured by processing each resistance value with each of the resistance/temprature maps for each of said first plurality of RTD's and means for transmitting in a known order the plurality of different temperatures for each of said first plurality of RTDs to a remote device which determines the correct temperature for each of said first plurality of RTDs from the plurality of temperatures transmitted for each RTD.
