MP Posted February 29, 2004 Report Share Posted February 29, 2004 What kind of accuracy are you looking for? Thermisters are not that bad for most applications. You might also look at the LM34 and LM35 from National Semiconductor.Again, you need to list how tight the spec. And how are you calibrating it? Another question: are you using a microprocessor to read it? The ADC resolution will also need to be high enough for the high accuracy.MP Quote Link to comment Share on other sites More sharing options...
