Modernization and automation of concrete-mixing plant (BSU) or other engineering objects that mandatory automated weighing and dosing of materials. Modern electronic sensors, Unlike the outdated mechanical gauges, allow you to include testimony about the presence and flow of materials in the automated control and accounting. In this case, virtually eliminated errors and mistakes associated with the "human factor". Moreover, the use of electronic weighing systems in various types of dispensing speeds up preparation of mixtures and to achieve maximum accuracy of repetition Technical recipe. Especially for weighing and batching of cement, chemical additives and other such substances. Electronic metering systems do not require constant monitoring and adjustment – all the processes automated and operator intervention is required only in exceptional cases.
In this case, virtually eliminated the possibility of fraud and theft by employees during dispensing, loading and / or shipment finished products. Reports on the processes that occur at the site are generated automatically stored in electronic memory. They can view or print at any time, as well as send e-mail or by sms-message. In contrast to the mechanical, electronic metering and weighing allows to obtain results of high accuracy over a relatively short time and with high reliability. The most expedient the process of modernization and automation engineering facility to replace outdated mechanical measuring parts on all dispensers to electronic sensors. Otherwise (with a combination of electronic and mechanical sensors) is difficult to ensure maximum system efficiency and achieve a low error in weighing and dosing.
Translation Stages dosing on strain gauge system. Strain-gauge system for determining mass of material is the most common and has tangible benefits not only to the mechanical systems of weighing, but also to systems based on piezoelectric or sensors. Strain gauges (full name of "weighing tensoresistance probes") are characterized by high accuracy, precision and accuracy, reliability and stability against the action of aggressive factors of the environment. The principle of operation of strain gage based on recording the pulses from the tensile forces and / or compression. Simplicity of design allows the sensors to get accurate readings even under the harshest conditions. Given variety of forms and breadth of capabilities, strain gauges can be equipped not only bin or silo, but almost any design in which the material for weighing or dosing. In order to ensure maximum dosage accuracy, the dispensers (especially designed for bulk materials) must be installed not less than three sensors, but better – six. This is due to the effect of shifting the center of gravity of the vessel when it filling of bulk materials. Predict this effect, or to consider an amendment to it in the presence of only one sensor is virtually impossible.
