FIELD: instrument making.;SUBSTANCE: pressure comprises a cylindrical body, where a unit of a holder is installed with a manometric spring of Bourdon, which with its free end is connected to a transmission pinion-sector mechanism. The pressure gauge at the face side comprises a protective glass and is equipped with an additional control pointer, which is combined with a device for simultaneous fixation of maximum pressure as pressure is exceeded, or, to the contrary, as pressure reduces in process of the pressure gauge operation. The pressure gauge is equipped with a device of angle A, in which the control pointer is fixed on the axis of an adjustment spring-loaded screw, installed in a bushing, which is fixed in the hole available in the centre of protective glass with the help of a nut and on the face side of the instrument with the help of a threaded bush.;EFFECT: expansion of functional capabilities of indicating devices such as indicating pressure gauges.;4 dwg
