LOAD CELLS-CAS

Load cells are sensors for measuring load or force which are frequently used both in
academic studies/ laboratories and in industrial facilities, storage tanks, silos, actuators,
pistons. Load Cells consists of models which works in compression only, tensioncompression
or measuring in special geometries like bending or shear.

The basic principle of operation is based on strain gauges. These small gauges which can measure unit deformations, are adhered in various configurations on a steel with well-known material characteristics. These strain gauges convert the physical deformation which occurs in the elastic region of the stress-strain curve due to the loading of the material, into electrical signals,thus enabling them to be acquired by the data acquisition system. Once the physical deformation data is measured in unit deformation(strain), it is possible to calculate the load being applied using various material specifications (elastic modulus, Poisson ratio etc.) The calibration steps which includes calculations using all these parameters are performed at the factory stage. The load cells are delivered to theresearcher with a calibration coefficient which can be used directly to calculate the physical load/force from the measured electrical voltage.
