DEVELOPMENT OF AN UPRIGHT TYPE DISPLACEMENT TRANSDUCER WITH LONG STROKE ASSUMING INSTALLATION IN BASE-ISOLATED STORY

The authors devised the mechanism of the displacement measurement assuming the installation of a displacement transducer in a base-isolated story and developed an upright type displacement transducer with a long stroke. In order to demonstrate that the transducer can follow the movement of a base-isolated story and can measure the displacement of the base-isolated story, dynamic loading tests using the specimen of the transducer were carried out. We confirmed that the specimen can measure the displacement appropriately during the movement of the maximum speed of 1.0 m/s and the random movement.
