Pressure sensing assembly

The utility model provides a pressure sensing assembly which comprises one or two full-bridge pressure sensing chips, when one full-bridge pressure chip is used, the area of the chip attached to the tangent line of a circular deformation line of a diaphragm can be 20-80%, full-bridge signals can be output, and when two full-bridge pressure chips are used, the area of the chip attached to the tangent line of the circular deformation line of the diaphragm can be 20-80%. The relative included angle between the positions of the two chips can be freely adjusted between 90 degrees and 270 degrees with the center of the metal diaphragm as the circle center on the horizontal plane, and two full-bridge signals are output at the same time. According to the utility model, one full-bridge chip is arranged and can be mounted at one time, so that the production efficiency is higher, the material consumption and the processing cost are lower, the movement space for mounting one chip is larger, the tolerance of the process i
