FIELD: measuring techniques.
SUBSTANCE: invention relates to a technique for measuring the relative permittivity and dielectric loss tangent of materials. The device contains a cylindrical ceramic resonator with a conductive coating applied to the inner surface, bounded on one side by the upper wall of the resonator with coupling holes located below the resonator end face, movable in the resonator cavity and relative to the resonator axis, and on the other side by a movable lower piston mounted on the floor rod, heater, temperature meter.
EFFECT: improving the accuracy of measuring the dielectric parameters of the materials under study during high-temperature heating.
