ABSTRACT:
An internal diameter measuring and scanning device for pipes, gun barrels and the like, wherein the arrangement is slidably axially movable through the pipe. The arrangement includes a guide body which is rotatably mounted in the pipe. A plurality of feeler fingers are mounted on the guide body and are outwardly biased so as to contact the internal wall surface of the pipe. The feeler fingers are operatively connected to stretch measuring strips which are adapted to emit electrical pulses in accordance with the measurements carried out by the feeler fingers. The electrical pulses are processed in a processing and evaluation unit. A measuring sled is connected to the guide body and is centered in the pipe by leaf springs or brush rings. A step-motor is connected to the guide body to stepwise advance it through the pipe from measuring region to measuring region.
