ELC is the acronym of “Electronic-Logical Control”: the pressure, in fact, is applied electro-mechanically, through the movements of a ball screw controlled at close loop by a high precision load cell (± 1 DaN). This system, exclusive Melchiorre, allows to have quick and continous regulations of the working pressure and, consequently, a perfect repeatability of the loads.
