Operating principle: load cells use the strain gauge operating principle to guarantee a perfect detection of the web tension. Strain gauges resistors are mounted on an inner metal
the foil of a load cell and connected to each other in a Wheatstone bridge able to convert a mechanical movement into an electrical signal, that must be amplied by suitable ampliers.
