There are so many similar portable platform scales on the market it can be very frustrating and confusing in selecting the best scale for your money. Yes, read below and you'll know the difference why there are similar looking products (Pelouze, Royal, etc) and some costing half as much.
The base on the VW320 Series uses 4 full bridge strain gauge industrial grade aluminum load cells. There are 4 resistive strain gauges per cell or total of 16 gauges for the VW-320-60 bench scale. Other competitive products may be using a single gauge with two inverted V lever system electro-mechanical base. Thirty years ago, the single gauge, glued on a metal bar (not 2024T4 aluminum) with weight transferred from two V-shape levers was the standard design in bathroom personal scales. The base was mainly painted steel that will easily rust and the two V-shape levers can easily bent or the knife on the lever edge may bent or bunt over short time. This design is equivalent to the Yugo or Pinto in cars.
To save costs and to provide the 4 full load cell marketing image, many manufacturers started using "4 load cells" bases. These 4 load cells are either single or double gauge 750 ohm or 1000 ohm gauges glued on a plated steel bar. Again, these are the standard design for bathroom scales not industrial scales. Accuracy class is typically 0.1% or less and not temperature compensated.
To save costs, manufacturers started using carbon steel as sensors instead of high quality aluminum that has 100 times better spring characteristics than carbon steel. Carbon steel is not a good material for weighing sensors, and in almost all cases fail cycle life tests of 10,000 times on full load. Product expectations from consumers buying a bathroom scale is very different from buying an industrial platform scales. These bases have only 4 to 8 gauges, VMC uses 16 on the VW320 platform scales.
Next, you are looking at the 330 lb / 150 kg base with 4 x 80 kg or total of 320 kg or 700 lb of sensor capacity. This is more then twice the rated capacity of the scale, ensuring that the shock loadings or corner loadings will not easily damage your scale base.
VMC scale bases are not made from one, not two but three deep drawn full stainless steel plates. The bottom plate ensures the scale will not rust and there are no paints to chip off. The center stainless steel plate is designed to give full support on the load cell sensor mountings. The top stainless steel plate provides even weight transfers to the center plate, and also a clean highly polished surface that can be easily cleaned.
Check out the internal and close up photos below. There are no moving parts, which means that there are less chances of damages and no wear and tear on the scale base. Compare this to the flexure double inverted V beam bases and the other 4 load cell bathroom scale bases, the difference is clear.
This portable bench scale comes standard with AC adapter. You can also use the scale with 6 AA batteries. Every unit comes standard with RS232C output for printer or computer interface. Weight display is large and easily readable and adjustable angle height bracket is also included as standard.
Common dry area applications are small animal weighing, parcels and boxes, automotive parts, dry cleaners, dried fruits, tools, tiles, wood products and building materials.
