  What types of industrial scales are there?

  
  

  Most industrial scales fall into two main categories: bench scales or floor scales. Additionally, there are forklift scales, pallet scales, and crane scales. At the core of all these scales are one or more load cells, connected to the weighing instrumentation.

  What are the capacities of industrial scales?

  
  

  Capacities range from 3 kg up to 20 tons. Crane scales can reach up to 50 tons or more.

  What dimensions and heights are available for weighing platforms?

  
  

  Dimensions typically start at 300 x 300 mm for bench scales, up to over 2500 x 2000 mm for floor scales. Platforms are usually square or rectangular. Standard heights range from 50 mm to 200 mm, depending on design and capacity.

  What construction materials are used for industrial scales?

  
  

  Scales are usually made of painted steel or stainless steel. Some painted steel scales may have a stainless steel cover for better environmental protection.

  What are industrial scales used for?

  
  

  The uses are extremely varied. They include simple weighing of goods/materials, piece counting, filling, mixing, recipe formulation, weighing, and inventory control.

  How accurate are industrial scales?

  
  

  This is a complex topic. Scales approved for commercial transactions usually have a minimum approved display interval calculated from the platform capacity divided by 3000 or 6000 divisions. For example, a 6000 kg weighing platform may have an approved display accuracy of 2 kg or 1 kg. Accuracy can be affected by factors such as temperature variations and other conditions.

  Is it necessary to calibrate industrial scales?

  
  

  All industrial scales must be regularly checked for calibration, especially if used for critical applications or approved for commercial transactions.

  Can industrial scales be washed?

  
  

  This depends on the design of the industrial scales, the construction material, and the sealing of the load cells. Scales used in the food, pharmaceutical, and chemical industries should be able to be washed regularly. Fully sealed stainless steel load cells are available for these applications.

  How do counting scales work?

  
  

  These scales are used to calculate the quantity of a large number of similar items (pieces) without counting them individually. A small known quantity of pieces to be counted is weighed on the scale, which then determines the average weight per item. The large quantity to be counted is then placed on the scales, and the quantity is calculated using the known average weight. Accuracy depends on the uniformity of the pieces and the size of the initial sample. For large quantities or heavier items, a dual-scale combination can be used, including low and high capacity scales connected together through a single electronic weight receiving instrument.

  What are hazardous area scales?

  
  

  These are scales used in designated areas where explosive materials, gases, and dust may be present. Gas filling scales are a good example. Special certification (ATEX) is required for scales operating in these areas. Bilanciai can provide scales for these applications.

  Are industrial scales portable?

  
  

  Most industrial scales can be moved to another location within a factory or warehouse. However, it is very important that after relocation they are carefully leveled in the new position.

  How robust are industrial scales?

  
  

  Overload or impact loading can damage scales. If a scale is to be used in a harsh operating environment, it is advisable to use a scale with a working capacity higher than the maximum weight to be measured.
