FIELD: instrument engineering. ^ SUBSTANCE: values of pressure to be measured are preset, transformed into electric signals and measured values are introduced into computer, and positions of pointer of manometer are registered which positions correspond to different values of pressure. Pressures are preset in internal cavity of manometer spring which is mechanically connected with manometer pointer. Registered positions of manometer pointer are scanned and introduced into computer in form of electric signals. Scale of manometer dial is modeled by means of computer. Data on built model of manometer dial scale is transmitted into printing unit which is used for making manometer scale on dial. ^ EFFECT: improved productivity; improved precision of readings of pointer manometer. ^ 6 cl, 1 dwg |
