Self-supported bridge-type weighing sensor

The utility model relates to a self-supporting bridging load cell in the field of load cell technology, which comprises an elastic basal body, a displacement groove, a force bearing chassis, force transmission ball socket, and electric resistance strain gauge. The utility model is characterized in that the overall structure with both ends supporting and intermediate portion bearing displays self-supporting bridging structure, the central portion of the top of the load cell is provided with a ball socket for force transmission, the elastic basal body and the force bearing chassis are designed integrally. The utility model provides a load cell, in particular to an integrated bridging load cell of which the configuration is with both ends supporting and intermediate ball socket bearing, wherein a deformation groove is positioned between the elastic basal body and the chassis, four blind holes are arranged in the central portion of the elastic body, the electric resistance strain gauge is arranged on the two adjacent wall (i.e. strain beam), both ends of the elastic body are provided with two symmetrical matching holes, one lateral edge of the elastic body is provided with a cable outgoing hole, wherein the overall structure forms an integrated bridging structure.
