Nettet4. aug. 2024 · Thermistors are used for CJC in thermocouples and are highly nonlinear. A constant current is passed through the thermistor, and the drop is measured by an … NettetAnother approach is to “linearize” the response from the thermistor by adding external circuitry by connecting a resistor in parallel with the thermistor. Some ICs already to this for you. Choosing the correct value and determining how to pick and linearize a region is an article in its own right.
