Rezumat
In numeroase procese industriale, parametrii optimi care decid calitatea si randamentul, precum si siguranta in
functionare a instalatiilor, depinde de masurarea corecta a presiunii unor agenti de lucru (apa, ulei, abur, aer comprimat,gaze). Masuratorile de presiune se bazeaza pe proprietati fluidice si magnetice ale fluidelor magnetice, care permit obtinerea de valori sau limitat de presiune intr-o incinta. Dispozitivul experimental prezentat se bazeaza pe pozitionarea
fluidului magnetic in interiorul a doua bobine cu ajutorul a doua membrane din materiale elastice.
Cuvinte cheie: controlul presiuniisenzor cu fluid magnetic
Abstract
In many industrial processes, the optimum parameters that determine the quality, efficiency and reliability the
installations depends on the correct measurement of agents working pressure (water, oil, steam, compressed air, gas). Pressure measurements are based on fluidic and magnetic proprieties on magnetic fluids, which allow obtaining values or limited of pressure in an inside. The experimental device presented is based on magnetic fluids positioned inside of two coils by the help of two membranes of elastic materials.
