The accuracy and performance of your weighbridge is dependent on the following factors:
- Mechanical design and build quality of the weighbridge structure
- Quality of critical components – load cells, mounting hardware and instrumentation
- Effectiveness of the calibration procedure
It is very important to have your weighbridge regularly calibrated and ideally checks should be made every 12 months. Owners of trade weighbridges have a legal responsibility to ensure their weighbridges are maintained within legal tolerances. Failure to do this can lead to prosecution and fines; trading standards have the power to close down weighbridges that do not comply.
Weightron carry out weighbridge calibrations in accordance with the UK Weighing Federation’s Calibration Code of Practice for Non-Automatic Weighing Machines, which lays down the clear legislative guidelines for the calibration process of legal for trade weighbridges and scales.
We are Certified for the initial verification and re-qualification of weighbridges as set out in our Module D Certificate issued by our Approved Body NMO and operate dedicated weighbridge test units around the UK. The calibration process involves the placing of UKAS traceable weights on the weighbridge in a prescribed manner. Tests are carried out to check and establish:
- Zero point
- Maximum capacity (Span)
- Linearity and Hysteresis
- Eccentric error (corner loading)
It is important to remember that you must have your weighbridge re-tested (re-verified) if you replace critical (approved) components such as load cells or instrumentation. Any replacement load cells must be approved by the relevant authorities for a particular weighbridge design/make.
Also remember that inaccurate weighing can lead to the inadvertent overloading of your vehicles – leaving you open to prosecution.
