The application of piezoceramic resonator for observation of nonconvert film shaping

It has been used radial mode of disc piezoceramic freguency sensor for observation of film shaping polimetilmetacrilat etilacetat solution at room temperature. The layer of solution has been placed on the base of disc. The time dependence of resonance freguency has been experimentally obtained. Mode guality decreasing and influence of the massensitivity has been discussed.
