Abstract
A weighing sensor with integrated adjusting feet comprises an electronic portion and a mechanical portion. The electronic portion comprises a signal transmission unit. The mechanical portion comprises a strain weighing sensor. A weighing signal output terminal of the strain weighing sensor is connected with an input terminal of the signal transmission unit. The mechanical portion also comprises a foot pad and a scale body connecting device. The strain weighing sensor is connected between the foot pad and the scale body connecting device. Compared with weighing sensors in the prior art, the weighing sensor can be directly installed onto a scale body, thereby completing the installation of a weighing platform, and the installation is extremely simple, convenient, time-saving, and labor-saving. Compared with traditional weighing sensors, the weighing sensor does not need adjusting feet, cable conductors or conjunction boxes when the weighing sensor is applied to the weighing platform; the four-corner correction can be automatically performed through software of a reception instrument; the space limitation can be prevented and the long-distance transmission can be realized; and in addition, thanks to the structural characteristics of the novel-structure weighing sensor, the weighing sensor can bear a relatively large impact force without damage.
