Pressure differentiating device

摘要

The present Invention relates to a pressure differentiating device used in systems to control smoke and heat spread, wherein the rotational speed governor with the processor (18) has a software that makes it possible to maintain the pre-set pressure difference while identifying the cubature and tightness of the object under control with the use of a neural network structure, and, by this means, the need to calibrate devices each time when the cubature and/or tightness has been changed is eliminated.
