#83649 - Low cost controller for temperature |
Hello ... I am trying to design a very low cost temperature controller , basically ON / OFF with settable hysteresis to control the overshoot/undershoot. I need to give some specs for it. It is meant for a furnace operation using a K/J type thermocouple. Would it be possible to get a band of about 3~4 Deg. over a temperature range of 600~800 deg, with this type of control? Also has anyone come across any 8051 derivative which accepts the thermocouple input (mV) directly ? I googled and got a MSP430 derivative which does just that (MSP430F423) but no 8051 chip. Would like to have some inputs from the forum members. Thanks in anticipation Thomas Fernando |
