Abstract

The invention relates to a balance weighing device, which comprises an elastic single body, a weighing support piece, a balance weighing tray support column, a balance weighing tray, an electromagnetic induction device and a photoelectric adjustment device, wherein the balance weighing tray support column is connected at an input end of the elastic single body through the weighing support piece; the top surface of the balance weighing tray support column is connected with a cone; the bottom surface of the balance weighing tray is provided with an inverted cone shaped groove matched with the cone at the center; four side walls of the balance weighing tray support column are attached with resistance strain gauges, the four resistance strain gauges are connected into a Wheatstone bridge through a wire, and an output end of the Wheatstone bridge is connected with an unbalanced load correction circuit. The balance weighing tray support column is provided with the resistance strain gauges, thereby being capable of accurately collecting unbalance loading deformation data, and processing the collected data through the unbalance loading correction circuit so as to achieve a purpose of fastand accurate unbalance loading adjustment.

Description

technical field [0001] The invention relates to the field of weighing devices, in particular to a balance weighing device and a calibration method. Background technique [0002] The traditional weighing sensor is assembled from more than one hundred discrete components. The principle and process are relatively mature at the theoretical level. Because the expansion coefficients of each discrete component are inconsistent, changes in temperature will have an adverse effect on the balance, and in actual production and use There are also the following problems: [0003] Large volume and heavy weight lead to poor repeatability of weighing and excessive time drift, which eventually leads to inaccurate weighing values. Moreover, traditional weighing sensors have higher requirements on the use environment. [0004] In the electronic balance production process, the traditional weighing sensor has a complex structure, a large number of parts, high requirements on the assembly person...
