摘要：
A temperature sensor is disclosed as having a resistance thermocouple, accommodated in a sensor housing, for detecting a process temperature. The thermocouple can be connected via a multipole electric line to an electronic temperature transmitter for measured-value conditioning, the resistance thermocouple being equipped for in-situ calibration with a Johnson noise thermometer for determination of a reference temperature.
