instrumentation. SUBSTANCE: invention can find use in testing of manometric devices of other types and for precise measurement of positive pressure in proper ranges. Dead-weight pressure-gauge tester has measurement piston column, gear for superimposition of loads, balancing unit, pipe-lines with working fluid and shut-off valves, mechanism of forced rotation of piston and reading unit. Pipe-lines with working fluid are connected in parallel between piston column and cylindrical reservoir, their inlets being connected to bellows press and their outlets being correspondingly linked to cylindrical reservoir and measurement piston column. EFFECT: raised productivity of dead-weight pressure-gauge tester thanks to reduced duration of transient process. 1 dwg
