METHOD OF MANUFACTURE OF CAPACITANCE-TYPE PRESSURE PICKUP Russian patent published in 1999 - IPC

FIELD: measuring pressure. SUBSTANCE: stacks of pickups assembled from rings of rigidly of diaphragm made from metal foil coated with dielectric film on either side, layers of adhesive and base are placed between two metal plates for simultaneous pressing of several stack. Rubber and duralumin plates of preset thickness which are laid between stacks ensure high quality and smooth surfaces of pickups. EFFECT: increased productivity of manufacture of low-cost pickups both for low pressure (1 Pa) and high pressure ((10⁷Pa)). 2 dwg
