WEIGH BRIDGE SYSTEM

WEIGH BRIDGE SYSTEM

A weighbridge is basically a big collection for trucks made of steel or concrete (or a combination of the two), which connects to a reading (the digital weight indicator) that displays the weight. The system allows for vehicle load weighing of goods and enables businesses to charge consumers for the weight of the load supplied or shipped. The definition is simple, but the technology is revolutionary and highly accurate to achieve the purpose.

The reliability and accuracy of a weighbridge device is of utmost importance. Inaccurate weights (i.e. too light or too heavy) may decrease income or lead to overcharging and risk ill will, loss of customers and problems with litigation. It should be noted that it is the owner of the weighbridge who is responsible for ensuring that the system is legal for commercial use and maintained as such (Weights & Measures Act 1985). Failure to do so makes the weighbridge owner/operating firm, not the weighing company responsible for prosecution. As a minimum, a Trading Standards Officer will shut down an authorized device (for commercial use) found to be weighing out of tolerance before it is fixed, re-calibrated and re-verified. This not only costs cash, but also effectively prohibits trading by a company or platform.

In short, precision over the long term must be ensured by a weighbridge. It must be engineered to achieve reliability and be sufficiently robust to cope with the toughest conditions and environments of the site. Therefore it is helpful to look at how a weighbridge accomplishes this mission by such design parameters and the variables that lead to defects, downtime or excessive repairs being weighed.

The load-cells, the highly accurate transducers that form the core of any weighing device, calculate the weight of the load on the weighbridge. They transform a small resistance shift into a functional electrical signal using strain gauges bonded on to a precisely machined part that deforms under load. This signal is then filtered by the indicator, measured and digitally displayed. Together with inferior assembly and weighbridge design, the wrong load-cell option will lead to poor efficiency, frequent failures and enormous revenue losses. For weighbridges, compression load cells are the most common option, and multi-column products such as those used by retain their accuracy and provide a reliable low-profile solution.

As weighing errors or load-cell failures may occur, the environment around them must be adequately monitored due to the precision engineering aspect of load-cells. This is especially important as the load-cell itself in a weighbridge system is a particularly expensive component. Furthermore, replacement means increased labor-related expenses, re-calibration, recruitment of a weighbridge calibration device and in the case of trade-approved systems, re-checking. Therefore it is of vital significance that this feature is preserved to the fullest.

A direct impact overload also results from the most apparent weighing failure, i.e. when one or more load cells have a load applied in excess of appropriate tolerances. Vehicle acceleration and momentum also cause the weighbridge to be applied to very large instantaneous loads, much greater than the static load predicted. A weighbridge should be built to withstand a large amount of overload to deal with this. The higher the built overload, the more stable and precise the weighing system would be in general.
