The purpose of the present work is the realization of an electronic micro processor controlled by a PIC16F877 to control the power of an Ultrasound Generator. This is a module meant to ease the reading and the reproducibility of the power of an ultrasonic generator with brand name, Vibracell Sonics & Materials that we used for homogenization of liquid foods. Operating parameters such as power and time supplied by the Ultrasound Generator to the suspensions of variable nature must be solved by suitable action on the process considered, Ultrasound Generator. The control of these parameters should be based on the desired quality of the liquid to be homogenised. Given the complex nature of the approach in controlling these parameters, their interpretation and reutilisation, this card was associated with a database manager named WINDEV14 MICROSOFT. The analysis method used is UP7. This work is a part of an application that we developed and named "Logiciel de Pilotage du Générateur d’Ultrasons" (LoPiGUlson; with english acronym: Control Software of Ultrasonic Generators). It is an application that allows not only to better coordinate research and monitoring of generator parameters but also the physical properties of liquid foods. The power digital control card established, highly sensitive and linear, is conditioned to obtain answers in a band width of 1 Watt and perform measurements on a range of 0 to 250 Watts. Its realization as a facilitator of dependency does not change the basic function of the ultrasound generator.
