PURPOSE:To obtain a thermocouple signal input device having a structure which executes accurate measurement of the temperature of a thermocouple connecting terminal part and causes neither inconvenience for work of construction non a human mistake. CONSTITUTION:A terminal stage 2 is provided in the horizontal direction on the surface of the lower part of a thermocouple signal input device 1. On this terminal stage 2, three adjacent terminals 2a, 3 and 2a are grouped in one set and the two terminals 2a and 2a at the opposite ends out of these three terminals in one set are made thermocouple connecting terminals 2a to which thermocouple input signals 6 are connected, while one terminal 3 located in the middle between the thermocouple connecting terminals 2a is made a fixed terminal 3 of a temperature sensor 4 measuring the temperature of connecting terminal parts 2a of the thermocouple input signals 6. The temperature sensor 4 is fitted to the fixed terminal 3 with an insulating substance of relatively small heat resistance interposed. |
