Electronic scale for loader

The utility model discloses an electronic scale of a loading machine, which belongs to weight metering equipment and solves the technical problem of big error caused by detecting the position of a dipper for modifying weight metered values in the form of discontinuity points in the prior art when a proximity switch is installed on the loading machine. The electronic scale comprises a big arm (1) of the loading machine, a hydraulic push rod (2), a pressure sensor (3) and a secondary instrument (4) arranged in a driving compartment of the loading machine; a displacement sensor (5) is arranged on the hydraulic push rod (2) and fixed on the external wall of an oil tank of the hydraulic push rod (2); a mechanical input end of the displacement sensor (5) is connected with a piston rod of the hydraulic push rod (2); and an electrical output end of the displacement sensor (5) is electrically connected with the secondary instrument (4). The electronic scale has simple structure, can be conveniently maintained and enha
