TEMPERATURE MEASUREMENT APPARATUS

PROBLEM TO BE SOLVED: To measure the temperature of a measuring channel depending on appropriate terminal temperatures even if forming a temperature distribution biased by heat of an external heating element by a method wherein a plurality of reference contact point temperature sensors are arranged at appropriate intervals in appropriate positions of a terminal assembly for distinguishing. SOLUTION: When a thermocouple temperature measuring process part 60 judges that a heat generating assembly 30 as an external heating element is not present, terminal temperatures of all measuring channels 1 to n use measuring temperature data of a reference contact point temperature sensor RJC-A to compute reference contact point compensation values of the terminal temperatures. On the other hand, when the thermocouple temperature measuring process part 60 judges that the heat generating assembly 30 is present, the terminal temperatures of a group of measuring channels 1 to x use the measuring temperature data of a reference contact point temperature sensor RJC-B and the terminal temperatures of a group of measuring channels (x+1) to n use the measuring temperature data of the reference contact point temperature sensor RJC-A to compute the reference contact point compensation values of the terminal temperatures.
