<P>PROBLEM TO BE SOLVED: To provide a device for monitoring the temperature of a suppression pool, which is capable of accurately determining abnormality of a temperature sensor regardless of an installation position of the temperature sensor. <P>SOLUTION: A device 1 for monitoring the temperature of a suppression pool includes: a water level sensor 4; a plurality of temperature sensors 2 installed at each of a plurality of water levels 31; a temperature deviation calculation circuit 3 for calculating, as a temperature deviation signal 100, a temperature deviation between measured temperature values of each temperature sensor 2 and the other temperature sensors 2 installed at the same water level 31 as the temperature sensor 2; a temperature deviation monitoring circuit 5 for determining abnormality of a temperature sensor 2; an alarm device for informing an operator of the temperature sensor 2 which has been determined to be abnormal; and an average temperature calculation circuit 7 which averages temperature values of normal temperature sensors 2 installed at water levels 31 lower than a measured water level value 101 to calculate an average temperature and displays the average temperature on a display device 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
