VIBRATION-STABLE MANOMETER Russian patent published in 1997 - IPC

FIELD: measurement of pressure on objects prone to vibrations. SUBSTANCE: manometer has case 1, Baurdon spring 2 fixed in holder with lug on end. Manometer is fitted with balanced disc 9 with central hole and eccentric profile groove 7 on periphery and two supports 13 with holes. It also has strap 11 with rotation axle 10 and vertical trajectory groove 12 in its upper part and cantilever 4 located on lug having two fingers 5 and 6. Strap 11 is anchored on case 1, disc is put on axle 10 of strap for rotation. Manometer includes wire spring compensator 8 installed in supports 13 of disc. Ends of compensator 8 are passed through holes in supports. Relation of distances form center of disc to fingers 5, 6 of cantilever is chosen multiple. EFFECT: increased vibration stability of manometer under vertical and side directions of vibration, enhanced reliability of manometer in operation. 2 dwg
