I understand the principles of the thermocouple, but have never looked at the functional circuitry. I was going off of manufacturer's specs without understanding the whole picture. (This is one reason that I think it's good to know assembly before learning a high level language) I also seem to have been a bit out to lunch when I suggested that +/- 2 degrees C was a small error in the 10 to 30 range. I think what I was trying to say is that there are cheap complete solutions available that do use thermocouples. I think, though, that I sortof didn't notice the lack of accuracy, and saw the 2% not the +/- 2 deg.C Yes, the more I look at it, the more I think that the LM35 is a pretty good solution. Especially in a performance/cost evaluation. - --Brendan -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.8 for non-commercial use iQA/AwUBPVrTHQVk8xtQuK+BEQJe3QCfe0jLc9o+ZNABE1cG1TJeVAu7FYsAoKku c43WXLAeRZgjD6YwZ3awb/KG =nhFm -----END PGP SIGNATURE----- -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
