Imagine you have a magic box that can tell you how heavy something is. This is like a digital weight indicator.
When you put something on the magic box, it sends a signal to a special computer inside that can tell how much it weighs. The computer then shows you the weight on a little screen, like a calculator.
But how does the computer know how much something weighs? Well, it does this by using something called a load cell. A load cell is like a tiny scale that can feel the weight of whatever is put on top of it.
So, when you put something on the magic box, the load cell feels how heavy it is and sends that information to the computer. The computer then uses that information to calculate how much the thing weighs and shows you the answer on the screen.
Digital weight indicators are used in all sorts of places, like on scales at the doctor's office or in industrial factories to weigh big things. They help people know how much something weighs quickly and accurately.
