Measuring instruments, measuring systems, and measuring methods

Abstract

A measuring instrument, mounted on a measuring object, comprises: a pair of arm members; a connecting portion disposed between the pair of arm members and connected to the pair of arm members; a pair of vibration sensors disposed on the side of the pair of arm members connected to the connecting portion and on the side of the arm members opposite in the length direction; and a pair of detection surfaces disposed on the pair of vibration sensors and abutting against the measuring object; wherein the pair of detection surfaces face each other. Preferably, the measuring instrument further comprises a position limiting member that limits the position of the measuring object when it abuts against the detection surfaces.
