Multichannel thermocouple measurement device

A multichannel thermocouple measurement device comprising:

• a thermocouple-thermistor pair;
• a terminal to which an analog signal of the thermocouple-thermistor pair is input, wherein the analog signal is of either a thermocouple or a thermistor belonging to the thermocouple-thermistor pair;
• a detection unit which comprises a multichannel analog-to-digital converter and converts the analog signal of the thermocouple-thermistor pair, which is input via the terminal, into a digital signal in the multichannel analog-to-digital converter;
• and
• a compensation unit for performing cold junction compensation of the thermocouple by receiving the digital signal of the detection unit,
• wherein the detection unit is provided in plurality, the plurality of the detection units are separately housed, and the terminal is an external terminal which is located outside of each of the detection unit,
• wherein the thermistor comprises a PCB board on which a thermistor chip is mounted, a pair of U-shaped terminals which protrude from the PCB board, and a printed wiring which electrically connects each U-shaped terminal and the thermistor chip so as to be detachably coupled to the terminal, and
• wherein the external terminal is composed of four terminals, with two terminals acting as a pair, such that the thermocouple and the thermistor can be connected simultaneously.
