PRESSURE TRANSDUCER Russian patent published in 2022 - IPC G01L9/04 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment, is intended for converting the pressure changes in various media into an electrical signal in a broad dynamic range of operation, and can be used in industrial processes, when measuring the pressure in soils under shock loads, and in experimental studies. The apparatus consists of a body, a perceiving membrane, a transmitting rod, elastic cantilever beams of equal bend resistance, a rectilinear hollow thick-walled cylinder, bodies of electrochemical cells with electrolyte, inserts, a disk, metal conductors, and output terminals. The rectilinear hollow thick-walled cylinder, inserts, and disk are made of solid materials, and the bodies of electrochemical cells are made of an elastic electrical insulation material. The elastic cantilever beams of equal bend resistance are rigidly clamped by the bases horizontally into the inner side wall of the rectilinear hollow cylinder around the circumference in two rows in pairs above each other with gaps, wherein bodies of electrochemical cells with electrolyte in the form of rectilinear hollow cylinders are placed at the points adjacent to the clamp points. One base of each cylinder is secured to the lower plane of the upper beam, and the other base is secured to the upper plane of the lower beam in each pair. Inserts are secured in the gaps between the free ends of each pair of cantilever beams, and the disk is secured at the end of the transmitting rod, wherein the disk is in contact with the free ends of all the upper beams. Each upper beam, starting from the first to the second to last pair, is connected via a metal conductor with the lower beam of the subsequent adjacent pair; and the metal conductor connected with the lower beam of the first pair and the metal conductor connected with the upper beam of the last pair are connected to the output terminals of the pressure transducer.

EFFECT: expansion in the dynamic range of operation and reduction in power consumption.
