| 摘要 |
A temperature monitoring apparatus has a plurality of cells held in contact with a heater unit having a temperature distribution, a plurality of pressure sensors for measuring pressure differences, a gas pipeline network connected between the plurality of cells and the plurality of pressure sensors and a data processing unit for calculating temperature differences between two of the plurality of cells on the basis of an initial temperature and an initial gas pressure of one of the plurality of cells measured before heating, and the temperature distribution measured by the temperature monitoring apparatus is accurate rather than a temperature monitoring apparatus using thermo couples.
