specific Embodiment approach 1

[0008] Embodiment 1: The electronic scale described in this embodiment is composed of a support structure and three weight sensors 1, the support structure is composed of three equal-length channel steels 2, and one end of the three channel steels 2 is fixedly connected together, And the included angle between any two adjacent channel steels 2 is 120°, and the three weight sensors 1 are respectively fixed on the upper surfaces of the three channel steels 2 .

[0009] In this embodiment, the fixed connection of the three channel steels 2 can be fixed by welding, so that the connection strength of the three channel steels 2 is high.

[0010] When the electronic scale described in this embodiment is in use, the object 3 to be measured is directly placed on the support frame, and directly contacts with the three weight sensors 1 to realize weighing. The signal output terminals of the three weight sensors 1 can be connected with the current The measurement display device connected ...

specific Embodiment approach 2

[0011] Embodiment 2: This embodiment is the electronic scale described in Embodiment 1. The difference is that the three weight sensors 1 are at the same distance from the joints of the three channel steels 2 .

specific Embodiment approach 3

[0012] Specific embodiment three: the difference between this embodiment and the electronic scale described in specific embodiment one or two is that the electronic scale also includes a data collector 4, and the data acquisition device 4 communicates with three weights through three data lines. The weight signal output end of the sensor 1 is connected, and the data collector 4 has a measurement data output port.

[0013] In this embodiment, a data collector 4 is added, and the data collector 4 is used to collect the weight signals of the three weight sensors 1, and calculate and obtain the measured weight signal according to the three collected weight signals. The data collector 4 added in this embodiment has a measurement data output port. In actual use, the data output port can be connected with devices such as a display, a data storage device, and a printing device to realize display, storage or printout of the measured weight information. , It can also be connected with d...

Abstract

The invention relates to an electronic weigher which belongs to a measuring instrument, in particular to a weight measuring instrument. The invention solves the problem of influence on measuring precision due to unstable system gravity center in the measuring process of the traditional large electronic weigher. In the invention, a unique umbrella-shaped steel triangular structure comprising three U-steels with equal lengths is used as a support structure, an included angle between every two adjacent U-steels is 120 degrees, and three weight sensors are respectively fixed on the upper surfaces of the three U-steels. The electronic weigher can also comprise a data acquisition device, and a display or a data memory or printing equipment, wherein the data acquisition device is used for converting weight signals obtained by the three weight sensors into measuring data for outputting; and the display, the data memory or the printing equipment is used for displaying, storing or printing and outputting the measuring data at the output end of the data acquisition device. The electronic weigher provided by the invention has the advantages of simple structure and high measuring precision and can effectively overcome the influence on weighing precision due to unstable system gravity center of the traditional large electronic weigher, and the measuring precision can meet the requirement of a scientific test.

Description

technical field [0001] The invention belongs to measuring instruments, in particular to a weight measuring instrument. Background technique [0002] There are many forms of existing scales, including steelyard scales, pallet (spring) scales, electronic scales, etc. Traditional scales with a small weighing range are mainly lever-type, and later developed into tray-type (spring) scales. With the advancement of science and technology, electronic scales have been developed on the basis of the original scales. Electronic scales are divided into small and large. Small electronic scales are called electronic balances because of their high precision, and large electronic scales are also called electronic balances. Scales are mainly used to weigh large-mass objects. Due to the limitation of sensor resolution and the structure of electronic scales, the weighing accuracy is not high due to the instability of the system center, which cannot meet the requirements of scientific research....
