This Thermocouple Amplifier project provides a simple, low-cost solution for measuring thermocouple temperature. This board simplifies many of the difficulties of measuring thermocouples output. An integrated temperature sensor performs cold junction compensation. A fixed-gain instrumentation amplifier amplifies the small thermocouple voltage to provide a 5 mV/°C output. The high common-mode rejection of the amplifier blocks […]
