dynamic characteristics f (P) = F0 + A1P + A2P2 + A3P3,
where f (P) - resonator frequency in case of running value of pressure, Hz ;
F0- resonator frequency in case of zero-point pressure, Hz;
r - running value of pressure, MPa;
À2, À3- coefficients of second and third order. They determine
the non-linearity (the value of which - less 0, 4 %) and are specified in case of order.
