耐放射線性の加速度および温度複合センサの開発
概要
The status monitoring of the stirrers installed in the reprocessing plant are carried out by monitoring the vibration of the bearing using the radiation-resistant acceleration sensors. Additionally it is furthermore effective to monitor the increase of the temperature due to the deterioration of the grease or the foreign substance invasion into it. RECO manufactured the prototype sensor which could measure both the acceleration and the temperature simultaneously and verified the proper performance before and after the irradiation test under the condition of 1000kGy, i.e. region of acceleration as fc~10KHz, and that of temperature as ~90℃.
