FIELD: test engineering.
SUBSTANCE: device comprises pipelines of supply and discharge of air with valves located on them, as well as the means of automatic program control of these valves. The structure of the means of automatic control comprises a pressure regulator, a pressure sensor, a program setting unit, two blocks of comparison, two blocks of setting the pressure levels and the logic element and connections to arrange interaction of these functional elements.
EFFECT: improved accuracy of development of loading programs, and reduction of technical means necessary to create plants of such type.
