A major misunderstanding Chinese high-speed vehicle dynamic weighing

What a major misunderstanding Chinese high-speed vehicle dynamic weighing is: because it is overloaded vehicles on the roads and bridges by increasing awareness of the harm of managers, domestic production and sales of almost two years more and more manufacturers of related equipment, many manufacturers are holding The enterprise equipment reached a few levels related to the accuracy of the certificate. In fact, the device is fine up to a few state-level accuracy standard, known as the WIM, the accuracy of the final equipment is installed in a local press after, through field testing and proven sets of equipment actually achieved accuracy. Because of the flatness of dynamic weighing system accuracy and actual installation pavement, weighing equipment layout, vehicle speed, the driver driving the vehicle the way of a great relationship, so test equipment at a factory or field calibration to achieve the accuracy and the accuracy of the actual installation may be very different. Static say can be calibrated at the factory, but said it must be dynamically calibrated to the actual installation of the authentication accuracy rating upon completion. We can also see that the international standard for standard weighing accuracy is not a device, but the device is installed in the one place, the system can actually reach accuracy. All test reports of the Company for a test report are actual installation point, please indicate the source http://obchina.com/tdx/ask/2014/0324/133.html
