Abstract:
    The utility model provides a weighing sensor includes an elastomer, a resistance strain foil, a sealing layer and a moistureproof film; a groove for releasing of stress is opened on the two ends of the upper and lower strain surface, and the thread hole for fixing on the left and right sides of the elastomer is isolated by the groove; and the moistureproof film is adhered between the resistance strain foil and the sealing layer. Thus, the stress produced when the elastomer is installed by the screw will not be passed to the resistance strain foil; the humidity can be prevented from permeating through pores generated by the silastic solidifying of the sealing layer and the load bearing characteristic curve of the weighing sensor is improved and the electrical property is improved, as a result, the high precision of the electronic scale is ensured and the working of the weighing sensor is more reliable and stable.
