Choose a mounting kit for shear beam load cells

This load cell is bolted to a fixed structure at one end and force is applied through a single point at the other end, causing the beam to bend and placing the strain gauge area under shear.

Shear as a measuring principle offers a good resistance against side loads and small sensitivity to the variation of loading position.

Load cells that use strain gauges are sensitive enough to detect very small changes in weight. The trick is to make sure that they react only to the weight you want to measure, not to other forces. To get accurate weight readings, you must carefully control how and where weight is applied.

A load cell should be installed so that the load is applied vertically throughout the entire weighing range. 

When the load cell is not installed properly, there are several types of forces that can affect its accuracy:

Angular loading

Angular loading occurs when a force that is not perfectly vertical is applied to a load cell.

Eccentric load

Eccentric loading occurs when a vertical force is applied to a load cell at a point other than its centre line. This problem can be caused by thermal expansion.

Side load

Side and end loading can be caused by thermal expansion, by misalignment, or by movement due to dynamic loading.

Torsional moment

Torsional loading occurs when a side force twists a load cell. It can be caused by structural deflection, system dynamics or misalignment.

Because environmental factors can affect the accuracy and safety of a weigh system, they must be considered during the design stage.

SCAIME offers different assembly kits suiting various mounting situations in order to minimize the adverse effects due to load introduction or environmental factors.
