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
The invention belongs to surveying instrument, be specifically related to a kind of weight measurement instrument.
Background technology
The form of existing scale has a variety of, comprises steelyard, pallet (spring) scale, electronic scales etc.The little scale of tradition range of weighing is based on lever, after develop into pellet type (spring) scale.Progress along with science and technology, on the basis of original scale, developed electronic scales, electronic scales is divided into small-sized and large-scale two kinds, and small-size electronic scale is called electronic balance because of the high people's custom of its precision, and large electronic scale is called platform scale again, be mainly used in the big mass objects of weighing, be subjected to the restriction of sensor resolution and electronic scales structure, often cause its weighing precision not high, do not satisfy the requirement of scientific research owing to system centre is unstable.
Summary of the invention
, cause system's unbalance when Measuring Object and influence the problem of measuring accuracy because the restriction of himself structure in order to reduce large electronic scale, the present invention proposes a kind of high novel high-precision electronic scale.
Electronic scales of the present invention is made up of supporting construction and three weight sensors, described supporting construction is made up of three isometric channel-section steels, one end of described three channel-section steels is fixed together, and the angle between adjacent two channel-section steels is 120 ° arbitrarily, and three weight sensors are separately fixed on the upper surface of three channel-section steels.
The present invention adopts the high channel-section steel of intensity to be welded into the umbrella shape triangular support structure, differ 120 ° between adjacent two channel-section steels, the upper end of every channel-section steel is fixed the weight sensor of a resolution appropriateness, in use, triangular support structure is placed in the plane, then object to be claimed is placed on this gusseted structure, make and wait to claim object directly to contact simultaneously with three weight sensors, at this moment, gather the weighing-up wave of three weight sensors, obtain to wait to claim the weight of object.Electronic scales of the present invention can keep sensor to contact with treating the direct of weighing object, prevent that large electronic scale system crank is to the influence of weighing precision in the past, can effectively overcome the not high shortcoming of other large electronic scale weighing precisions, reach the purpose of the weighing precision that requires.
Electronic scales of the present invention is novel structure not only, and its weighing precision height, and during at 3000kg-5000kg, weighing precision can reach 50g, far above existing similar electronic scales, can satisfy the requirement of scientific experimentation in weighing object gross mass.
