This article will help you understand how to get the best output from your weighbridges in realistic scenario in India. We look into how weight difference in weighbridges is a constant challenge to businesses and how to overcome it.
Having your weighbridge displaying accurate weight is very challenging. Weighbridges are a precision instrument that measures trucks with load. And this is quite a task for instrument that needs to deliver precision.
It is important understand the common practices in regards to the weighbridge. This will give us a clear picture how prevalent is the “weight difference” situations.
Or say you have calibrated your Weighbridge- A against Weighbridge-B a few months back. You have matched the weight measured in A to be same as that of B by nullifying the weight difference between them. If you think that the weight difference of A and B will be same then you might, to a great extent, be wrong.
This does not mean that there has been a mistake in measuring the weight, it simply means that your weighbridge needs a recalibration.
Recalibration is not the challenge. The challenge is when or how can one identify that the weight difference in weighbridge demands recalibration.
Let us look at another very realistic scenario in terms of weighbridge usage that leads to a weight difference in weighbridges.
We have been almost blaring in each of our article regarding the importance of managing linearity issue. We find consistently businesses ignoring it.
If we put it straight forward – You are draining your profits if you overlook non-linearity error in your weighbridge.
The ideal way to get your weigh bridges calibrated is by using test weights. As it is tough to find test weights we rather use a way around.
We calibrate one weighbridge against another with a single truck load. Now the non-linearity in simple terms mean that the weight difference in weighbridges differ with different weight.
The correct way of calibrating weighbridges against a mother weighbridge is to follow a five step process. In the 5 step process the weight difference in weighbridges in full spectrum of its capacity is measured and compared against the mother weighbridge. It is then calibrated against different weight range. This way your weighbridge is covered against the linearity issue.
In case you are getting your load cells replaced make sure that you get pre calibrated load cells.
Depending on the frequency of weighbridge usage it is a good practice to calibrate your weighbridge once or twice in 3 months.
As always stressed, keep a proper maintenance schedule/process of your weighbridge. After all your weighbridge is responsible for the most fundamental process of your business – weighing.
