Using Dummy load cells

Most process weighing system installations involve the 'craning' or otherwise 'lifting-in' of tanks or silos. If this is the case, it is always prudent to use dummy mounting assemblies during this procedure to avoid damaging the load cells. Well designed, modern mounting hardware assemblies usually now allow the fitting of these in the jacked up position without the load cell. This permits adjustments to be made, final welding to be carried out and pipework to be aligned and connected before the load cells are installed. The levels of dummy assemblies should be adjusted to align with both the support structure and the load receiving element. This is usually achieved by adjusting the level of the base plates before they are finally grouted in position. If the load cells are mounted on top of steel structures, then levelling can be carried out using steel spacers or shims.
