To account for bulk materials and determine the mass, there are conveyor scales. They are used in the construction, mining, agricultural food industries, a variety of grain storage facilities and process chains.
How it works
Conveyor scales consist of a frame connected by units with special strain gauges. They are attached to the corners of the frame on cross beams that are built into the conveyor. From the sensors there are wires that are connected to the counting device. The speed sensor converts the belt speed into a pulse signal, which is transmitted to the strain gauge. Everything is covered by a special protective cover.
The weighing system converts analog signals that come from strain gauge water sensors and conveyor belt speed control sensors. The signals from the load cells of the conveyor scales are directly proportional to the density of the material that is transported along the conveyor belt. The received signals are processed, as a result, the speed of work, material density, consumption and other indicators that are needed to control production processes are calculated. Data can be transferred to your computer as well as to other external devices, depending on your settings.
Benefits
Belt scales have the following advantages:
- resistance to temperature changes (from -20 to +50 С);
- easy to integrate into the conveyor belt;
- a high degree of protection against mechanical and other adverse effects;
- data accuracy thanks to special sensors. Gimmicks like mechanical buzz, slipping the tape to the side, etc. do not affect performance;
- weighing accuracy does not affect the angle of material pouring;
- quickly collapsible design allows you to easily bring to the desired point of transportation;
Thanks to the latest software on conveyor scales, data can be transferred to 1C, exported to exel. As a standard, 2 accounts are given for access: the administrator and directly for the employee. All results are saved and stored at the time specified in the enterprise. It is also possible to receive several types of reports on the operation of the entire system.
As you can see, conveyor scales are simply irreplaceable at many enterprises. They help to take into account products, materials, weed out rejects and much more.
