<P>PROBLEM TO BE SOLVED: To provide a temperature measurement device for measuring the temperature of a rotor, in particular, a temperature measurement device able to measure the temperature of a plurality of parts of a rotor. <P>SOLUTION: The temperature measurement device 10 has a temperature detection part, provided on the rotor 11; and a measurement part, provided on a fixed side, which displays and/or records a temperature. The detection part has a piezoelectric resonator 15 and a rotation side antenna 12 connected to the piezoelectric resonator 15. The measurement part includes a measuring instrument 17 with measuring means for a singular frequency corresponding to a measured temperature, and a fixed side antenna 13. The rotation side antenna 12 and the fixed side antenna 13 are connected without being in contact with each other. The piezoelectric resonator 15 is accommodated in a ceramic container. <P>COPYRIGHT: (C)2013,JPO&INPIT |
