I am trying to design a very low cost temperature controller , basically ON / OFF with settable hysteresis to control the overshoot/undershoot. Have a look at datasheet of OP295 to see how k-type thermocouple signal can be handled using simple OPamp. If you use a double OPamp you can use the one for amplifying the thermocouple signal, while the other can perform a simple comparator with hysteresis. But if you want to self build something very precise, then follow Steve's recommendation. Kai |
