Every industrial sector, along with agriculture, will not be able to act without weighing equipment. It also applies when delivering goods to warehouses, to the customs of various transport nodes. In our time apply a variety of types of weights depending on their destination and achieve goals. For example, the industry used crane, platform, truck scales and other forms designed to weighing large loads. Thus, the carload scales can accurately indicate the load weight up to 200 m. In general, an accurate weight control to avoid significant extra costs when dealing with suppliers or recipients of goods and related reliability issues, the possible occurrence of emergency cases. Thus, the scale cars are for the most correct account of the mass transported by motor transport products, whose number is rapidly increasing from year to year.
They make it possible to solve many problems both in the sphere of state control and supervision, and in the industrial sector, transport, trade, agriculture economy. First of all, weigh the empty vehicle, or filled with fluid and loose cargoes. Truck scales are available in various shapes and structures depending on their function – weighing technology for stationary or in motion, in whole, or poosno . For the latter, weighing the structure of such devices is then made of several sections. The most important parameters are the weights of motor Weighing and platform size. These criteria and show what kind of vehicle can be weighed in this kind of truck scales. If the cargo is planned to transport over long distances, in this case is reasonable to deliver it by rail. Then, taking into account the traffic better than any operating track scales.
Features of their shape also depends on the kind and method of weighting. Thus, the most accurate, but also the most time consuming, is static weighing of a standing train at gruzopriemnoy platform. There are scales used for weighing go cars (with fluid or loose and hard goods) in the running, at speeds from 3 to 10 km / h. However, at this Weighing slightly higher error of weighing. There is a series of multi-purpose car scales, allows us to combine the above types of weighing goods depending on their shape. Track scales to weigh petroleum products are the foundation pavement design, which gives the opportunity to weigh without uncoupling the four-and eight-axle tank cars with a minuscule error. Libra automobile and wagon consist of the load receptor (1 to 3 sections) and directly measuring device – load cells connected to each other. The length of the sections varies depending on the destination device. The most important a component of the weights used strain gauge measuring weight, one or more sensors connected to a device matching, which compares the received data from multiple sensors, converts the analog signal in a discrete, but also takes into account a correction for air temperature (- 40 C to + 45 C). The most modern and advanced strain gauges, first broadcast digital signal, ensuring the highest accuracy when any conditions. The sensor body weight is sealed, made of stainless steel and filled with inert gas. In order to reduce wear bearing surfaces of the meter are covered with silicon nitride. Now road and track scales equipped with a large set of devices display the weight from simple to complex weighted indicators of independent controllers that send information to a computer network company.
