Load cell QS-А
Basic device of the up-to-date weight measuring systems is load cells, construction of which is based on resilient mechanical member which is subject to deformation with overlaid on it strain-gauge bridge consisting of resistive-strain sensors connected in different electric networks. With effect of external load to sensor as a result of deformation symmetry of measuring bridge is upset and electrical signal proportional to applied effect to sensor is appeared at measuring terminals.
