Linearisation of the response from a platinum resistance thermometer
James H. Nobbs · Journal of Physics E Scientific Instruments · 1982
Two simple circuits of low construction cost have been developed in which the current through a platinum thermometer element (DIN 43760) depends on its resistance in such a way as to make the voltage generated across it vary linearly with temperature. The linearity over the temperature range -150 degrees C to greater than 300 degrees C is to within 0.2 degrees C.
