[Nomograms for calculating the parameters of a system of recording intracavitary pressure through sounds].
The signal of the intracavitary pressure registered through a probe is, as a rule, distorted by fluctuations of the liquid column in the probe. Nomograms enabling the velocity of the sound wave and the own frequency oscillations of the measuring system to be found from the size of the probe, elastic modulus of its material and elasticity of the bulk of the guage are described. In this way a selection of probes to secure high-quality recording of the signal is facilitated. An example of a calculation with the use of the nomograms is given.
