Abstract
The invention discloses a weighing device, which comprises a bearing part and a receiving feedback part, wherein the bearing part comprises a plurality of elastic devices, and each elastic device bears an object to be weighed. The receiving feedback part is used for receiving deformation quantity produced by the elastic devices to accumulate the deformation quantity and get a total deformation quantity and for transmitting correspondent signal information according to the total deformation quantity. The deformation quantity when the weighing device bears a load is transmitted by the elastic devices to the receiving feedback device, so the displacement stroke of an output device is stable.
