Sector scanning ultrasonic inspection apparatus

摘要

This is an ultrasonic transducer scanning support system comprising at least three arms serially joined in pivotal relation one to the other and to a base. Three position transponders are mounted on the base with each of the pivoted arms operatively coupled to a transponder whereby signals are developed representative of the position of a transducer mounted on the end of the third arm which control the origin of an indicating means to correspond to the position of the transducer.
