The AD597 IC does a job of interpreting the thermocouple signal, comparing and filtering it and outputting a signal of 10mV/degreeC. You can not intervene on the thermocouple side because that is very...

View ArticleRe: how to measure more than 500°C on the electronics ?
... you can measure any temperature with a 0-5 Volts signal, when you select proper resistor bridges to 'fit' the signal in this range. I've done this for temps from 0 to 800 degC with a PT100 as...

Use a different thermocouple amplifier. The MAX6675 mentioned in a previous post is obsolete, but the MAX31855 is nearly compatible with it. Search ebay, Sparkfun etc. for MAX31855 breakout boards.
