Why is Technology so important in weighing scales?

What is the IN THING in Weighing Scales?

First we need to understand what exactly is a Digital Weighing Scale. A Weighing Scale has a Loadcell – Which is essentially a balanced wheatsons bridge connected to a potentiometer. When a force is applied the wheatson’s bridge becomes unbalanced, and gives a voltage reading at the potentiometer. This is picked up by the ADC counter and converted into a digital output that is finally displayed on the screen. Yes. That’s it, its that simple

If the above was Greek and Latin for you, in simple words, the weighing scale is a very simple device. It has a Loadcell, that detects the weight and it has an indicator that shows the weight.

Now if its so simple whey do you need technology in a weighing scale at all. It shouldn’t be that complicated right? Well, as customers want more and more features into a weighing scale, and as they demand even greater precision, that’s where technology comes in. So ten years back, you could have a weighing scale which would have nothing but a Loadcell, very rudimentary A to D convertor and the display unit. As we made more feature packed scales, we started using microprocessors, having speeds of 1500 Mhz for the weighing scale. Compare this with the chipset in 1990s where 500 Hz was more than enough.

The following is a sample chipset from Hindustan Scale Company’s Weighing Scale.HSCo Motherboard for Weighing Scales

The newer one has atleast 200 times more processing power and 20,000 times more memory. You could run a computer on our newer version of Motherboards.We have to use this powerful Motherboards to give you a higher accuracy and sensitivity of the weighing scales. So if we say that Hindustan Scale Co (HSCo) Motherboards have an internal count of 30,00,000, it means that the Motherboard will pick up even the 1 in 30,00,000 variations in ADC count.

These weighing scale Motherboard are designed and developed by the Blue Whale Technologies – BWT
