The invention concerns a pneumatic measuring device for the measurement of proximity, the deviation from flatness and the diameter of bores.In accordance with this invention, the first version of the pneumatic measuring device consists of a body assembled with a measuring nozzle equipped with a pin. The body is equipped with a ring chamber and a flare component that continues with a spout. There are holes in the measuring nozzle, and the pin contains in its turn a centre hole.In accordance with this invention, the second version of the first example of the pneumatic measuring device consists of a body and a nozzle, assembled through an expanded nozzle. The body is equipped with a pin that continues with a conical tip and has a centre hole linked to radial holes and openings located around the pin, and on the bottom with a ring chamber. The expanded nozzle has a flare component that continues with a cylindrical section that forms a nozzle. The nozzle contains a central hole.In accordance with this invention, the second example of this pneumatic measuring device consists of a threaded gauge and a lid. The gauge has an outlet pipe connection on the shaft, in which radial holes end, and axial channels that are connected to radial channels. The lid has a connecting pipe that leads to a ring chamber and a nozzle that continues with a flare component.
