kylmäliitäntäanturi
A kylmäliitäntäanturi, or cold junction sensor, is a type of temperature sensor used to measure the temperature at the junction of two dissimilar metals, typically in a thermocouple. Thermocouples generate a voltage that is proportional to the temperature difference between their measuring junction and a reference junction. To accurately determine the temperature at the measuring junction, the temperature of the reference junction, known as the cold junction, must also be known. The kylmäliitäntäanturi provides this crucial reference temperature measurement.
Common types of kylmäliitäntäanturi include thermistors, RTDs (resistance temperature detectors), and semiconductor-based temperature sensors. These sensors
