Abstract
Appareil de mesure de la masse volumique et de la viscosité dynamique d'un fluide par oscillateur électromécanique comprenant une bobine d'excitation 23 d'une lame vibrante 24 plongée dans le fluide, un quartz piézo-électrique 25, un préamplificateur 26 et un circuit de rétro-action 29. Selon l'invention, le circuit 29 comprend des moyens de décaler alternativement la phase du signal de contre-réaction 33 de + et - 40 degrés par rapport au signal de sortie 33', valeurs pour lesquelles la fréquence de ce dernier est respectivement indépendante de la masse volumique et de la viscosité. Un commutateur électronique 35'', synchronisé sur ces sauts de phase, permet d'obtenir des signaux respectifs directement proportionnels à la masse volumique et à la viscosité, via deux générateurs des fonctions numériques appropriés 30, 30'.
