Weighing stuff in any industry can be tough. When it comes to weighing things, you might think of yourself standing on the bathroom scale. That is pretty easy to do. It is just you, and it only takes a couple of seconds. Now imagine you needed to weigh 10,000 people a day and it took five seconds to weigh each person. That would make for a long day with only one scale. In manufacturing and industrial applications electronic scales that use things such as shear beam load cells that are connected to computers running weighing software are faster. No one needs to write down anything. Each product is labeled, scanned, weighed, tabulated and packaged.
The old spring scales with analog dials were great for precision weighing on a small scale. Digital scales that are standalone units are great for small volume too. If you are going to be weighing products on a production line, you need computerization and automation to be able to keep up even with minimal consumer demand. I have seen factories that are turning out hundreds of thousands of products in a single day. The facilities may run around the clock operating three shifts at peak capacity year round. I have seen production lines where the products are not only weighed, they are run through scanners to detect any metal too. They do that a lot in food products to prevent metal from the production equipment getting into the products. It is not unheard of for a bolt or screw to fall out of a machine.
I am amazed at the massive production lines that are producing the products we use every day. I see some lines that might make one product in the morning, and a different one for second shift. That is why you see labels on products that tell you that it was manufactured on equipment that also produces products that contain soy, peanuts, milk and shellfish products. Some people’s allergies are so sensitive that just a few molecules of leftover peanut dust can trigger a reaction.
