Abstract
A method for measuring the concentration of chemicals in gases and liquids using sensors based on piezoelectric resonators with sensitive films of elastic polymers is considered. It is shown that the metrological characteristics of sensors with elastic films, the thickness of which is greater than the depth of penetration of oscillations of the resonator into the film, are determined by the vibrorheological properties of the film. Parameters of the acetone vapor sensor based on butyl acetate film are given.
