App note: High precision temperature measurement with thermocouples

The sensitivity of modern thermocouple is around o.1C over a range which spans from -270C to 1750C. Here is an app note from Maxim on how to built high precision temperature acquisition systems based on thermocouple sensors. One examples uses a 24bit ADCs for high precision measurement. Another example use a MAX31855 thermocouple-to-SPI converter for […]
