Abstract
The invention discloses a double-range electronic car scale which comprises at least two weighing platforms connected through a connection frame. Double-range weighing sensors are arranged under the weighing platforms, the output ends of the double-range weighing sensors are connected with a junction box, the output end of the junction box is connected with a display device, and a signal adjustment unit and a microprocessor are arranged in the junction box. Each double-range weighing sensor comprises a protection housing, an upper cover plate arranged on the upper end portion of the protection housing and a lower cover plate arranged on the lower end portion of the protection housing. An elastic body is arranged in each protection housing and comprises a first strain area and a second strain area. The first strain areas are respectively provided with a first strain meter, the second strain areas are respectively provided with a second strain meter, and the ranges of the first strain meters are larger than those of the second strain meters. The double-range electronic car scale has the advantages that the double ranges are provided, accuracy is guaranteed, and the structure is simple.
Description
Technical field
The present invention relates to a kind of double-range electronic vehicle weighing apparatus.
Background technology
Along with the popularization and application of electronic vehicle weighing apparatus, people are more and more higher to the requirement of truck scale, mainly comprise weighing range and precision, weighing range from before 0～100 ton, progressively bring up to current 0～250 ton.Requirement according to CIII weighing apparatus: the weighing apparatus scale division value e that maximum weighing is 20 tons is generally 5kg or 10kg, identifies that for the first time the limits of error are 7.5kg or 15kg, and in use, the weighing apparatus limits of error are 15kg or 30kg; And maximum weighing is 250 tons of weighing apparatus scale division values, be 50kg or 100kg, identify that for the first time the limits of error are 75kg or 150kg, in use, the weighing apparatus limits of error are 150kg or 300kg, 10～20 times of truck scale (empty wagons weighing apparatus) limits of error that 250 tons of truck scales (loaded vehicle weighing apparatus) limits of error are 20 tons.In order to meet the weighing accuracy requirement of different range sections, the user often will install the truck scale of several different weighing ranges, perhaps adopt the truck scale of several independent weighing platform independent assortment modes, so just greatly increase purchase cost, foundation construction expense, maintenance cost and the cost of labor of truck scale, also increased the area occupied of fabricating yard simultaneously.
