FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used to measure physical parameters of gases by radio wave methods in a wide range of pressures. Essence of the disclosed method consists in the emergence of a new sequence of operations on signals, and the disclosed device in the introduction of new units and connections between them.
EFFECT: measurement of the frequency of the signal of a generator placed in a high-pressure volume, while minimizing the high-pressure volume, which means using a minimum number of elements of radio-electronic equipment located in the high-pressure volume.
