The application of a bridge scale usually consists mainly in the used superstructure located on the platform. It can be a construction for hanging big-bags or placing a container, hopper, etc. The picture is actually a hopper scale for bulk raw materials. The scale is filled with a screw feeder, the sealing lids reduce dust during filling.
The advantage of bridge - platform scales is that with a suitable choice of components, ie strain gauge and evaluation unit, it is possible to obtain an officially verifiable weight for commercial communication - a specified meter. Official verification is performed exclusively by CMI.
In this way, it is possible to create a device, a line with an officially verifiable weight with both automatic and non-automatic operation.
