Load cell designs are classified on various bases.
They are classified according to the
Types of output signal generated
Way they detect weight
Compression: Compression load cells measure a pushing together force along a single axis
Tension: Tension load cells measure a pulling apart force along a single axis
Shear: Shear load cells measure the displacement of a structural element to find out force. Shear cell types for load sensors include shear beam, bending beam, or single point bending beam.
