Abstract

According to one embodiment, a temperature measurement system including: a plurality of thermocouples; a transmission signal conversion unit configured to convert, to a transmission signal, the thermo-electromotive force generated by each of the plurality of the thermocouple and configured to output the transmission signal; a plurality of transmission units configured to transmit the transmission signal outputted from the transmission signal conversion unit; a first connection unit configured to connect between each of the plurality of the transmission units; a second connection unit configured to connect at least one of the plurality of transmission units to a processing unit configured to process the transmission signal; and a housing unit configured to house at least the first connection unit.

Claims

1. A temperature measurement system comprising:

a plurality of thermocouples;

a transmission signal conversion unit configured to convert, to a transmission signal, the thermo-electromotive force generated by each of the plurality of the thermocouple and configured to output the transmission signal;

a plurality of transmission units configured to transmit the transmission signal outputted from the transmission signal conversion unit;

a first connection unit configured to connect between each of the plurality of the transmission units;

a second connection unit configured to connect at least one of the plurality of transmission units to a processing unit configured to process the transmission signal; and

a housing unit configured to house at least the first connection unit.

2. The temperature measurement system according to claim 1, wherein the housing unit is a housing has a self-closing property.

3. The temperature measurement system according to claim 2, wherein

the first connection unit connects between each of the plurality of the transmission units in series, and

each of the plurality of the transmission units transmits the transmission signal via the first connection unit so as to allow the transmission signal to be transmitted to the processing unit via the second connection unit.

4. The temperature measurement system according to claim 3, wherein

the housing unit further houses the transmission signal conversion unit and the plurality of transmission units, and

each of the plurality of the thermocouples is connected to the transmission signal conversion unit in the housing unit.

5. The temperature measurement system according to claim 1, further comprising:

a relay unit connected to each of the plurality of the thermocouples; and

a third connection unit configured to connect the relay unit to the transmission signal conversion unit.

6. The temperature measurement system according to claim 5, wherein

the third connection unit is a compensation lead wire, and
