Precision Thermocouple Amplifiers with Cold Junction Compensation – Temperature Range −25°C to +400°C
https://www.electronics-lab.com/project/precision-thermocouple-amplifiers-with-cold-junction-compensation-temperature-range-%e2%88%9225c-to-400c/
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 […]
