る細管検査用のプローブ。 It consists of a probe body that has a built-in motor and transmission mechanism and is connected to an operating device, a probe head that has a built-in detection element and a coil facing it, and a transmission member that connects the two. In a probe that is moved in a direction to inspect the inner surface of a tube, the probe body and the probe head are connected by a flexible shaft, and a flexible, low-friction protective tube is fitted on the outside of the flexible shaft so as not to rotate. A probe for tubule inspection.
