MEASURING CONVERTER OF PRESSURE DIFFERENCE Russian patent published in 2005 - IPC

FIELD: measuring engineering.

SUBSTANCE: converter comprises base and flange. The space of the base receives strain gauge converter connected with the electronic converter and provided with the strain resistors and lever connected to the rigid center of the measuring corrugated diaphragm through the tie. The diaphragm is secured over periphery to the surface of the additional base. The base receives flexible distributor that defines the pressure-tight chamber together with the outer side of the strain converter. The pressure-tight space is filled with dielectric liquid. The additional separating diaphragm is mounted over the periphery of the additional base from the side of the flange at a distance from the measuring corrugated diaphragm and defines the second pressure-tight chamber made of capsule and defines with it the second pressure-tight space made of a capsule filled with the separating liquid. The controllable pressure is supplied through the openings made in the base and flange.

EFFECT: enhanced reliability.
