cold-junction compensation
PrintAn artificial reference level that compensates for ambient temperature variations in thermocouple measurement circuits.
IC temperature sensors are linear and their output is expressed as mV/°C. A 10 mV/°C sensor, for example, outputs 250 mV at 25°C. Thermistor outputs, however, are nonlinear. Therefore, thermistor output is specified as the voltage range over a defined temperature range (x volts at 50°C to y volts at 0°C).
