Abstract

PURPOSE: To provide a non-contacted type device having no sliding portion by detecting change in length of a rotating body in the direction of axis by time lag between the ultrasonic wave irradiated on the end faces in the axis direction of the rotating body and reflected wave and measuring the temperature by converting said time lag.
