FIELD: engineering of pneumatic measuring equipment, possible use for measuring non-straightness of apertures with lesser diameters.
SUBSTANCE: device consists of pneumatic measuring device, connected to sensitive element in form of pneumatic measuring plug. Device additionally has electronic information processing block and indicator with digital and limit scales. Pneumatic measuring plug is provided with system of measuring nozzles, two of which are positioned on one generatrix of cylinder-shaped surface of measuring plug at certain distance from central portion symmetrically to one another, and two others are on diametrically opposite generatrix in its central portion.
EFFECT: increased sensitivity and precision of measurement.
