摘要:
An integrated cold junction (108) compensation system for a thermocouple (100) connection is disclosed. The system includes a temperature sensor (136) integrated with a terminal (134) at which the thermocouple wires (102, 104) terminate. The temperature sensor (136) is integrated with the terminal (134) proximal to a cold junction (108) of a thermocouple (100), such that the temperature at the sensor (136) location is substantially equal to that at the cold junction (108). The temperature sensor (136) is further in electrical signal isolation from a circuit carrying voltage output by the thermocouple (100).
