  • Setting-free resistive temperature device (RTD) measuring module
    Patent number: 6655835
    Abstract: The apparatus which is located separately from the RTD includes means for measuring the resistance of a plurality of RTDs present at a selected site, the RTDs being those of a number of different RTD types. The module includes means for storing the resistance/temperature map for each of the plurality of RTDs and for determining the temperatures associated with said resistances from the resistance/temperature maps. The resulting plurality of temperatures for each RTD, respectively, is then transmitted in a known order to a remote protective relay which determines the correct temperature for each RTD connected to the module.
