Abstract
An improved method is presented for designing a temperature measuring transducer, the electrical circuit of which comprises an unbalanced br idge, in one arm of which is a platinum resistance thermometer, and co ntaining a differential amplifier with feedback. Values are given for the coefficients, the minimum linearization error is determined, and a n example is also given of the practical design of the transducer, usi ng the given coefficients. A determination is made of the limiting ach ievable accuracy in linearizing the output voltage of the measuring tr ansducer, as a function of the range of measured temperature.
