Способ возбуждения и измерения частоты колебаний колебательного звена резонансных датчиков, при котором возбудителем создают колебание колебательного звена, затем воспринимают это колебание и через отрицательную обратную связь воздействуют на возбудитель, вызвав собственные колебания колебательного звена, после чего измеряют частоту этих колебаний, по которой судят о величине контролируемого физического параметра, отличающийся тем, что колебание создают напором струи текучей среды из выходного сопла эжектора, примыкающего к зоне движения колебательного звена, воздействуют на этот напор через внутреннюю обратную связь эжектора и измеряют частоту изменения давления-вакуума в камере между входным и выходным соплами эжектора, в которой отслеживается частота собственных колебаний колебательного звена.The method of excitation and measuring the frequency of oscillations of the vibrational link of the resonant sensors, in which the pathogen creates the vibration of the vibrational link, then perceives this vibration and through the negative feedback acts on the pathogen, causing its own vibration of the vibrational link, and then measure the frequency of these vibrations, which is used to judge the value controlled physical parameter, characterized in that the oscillation is generated by the pressure of the jet of fluid from the outlet nozzle of the ejector adjacent to the zone d the movement of the oscillatory link, act on this pressure through the internal feedback of the ejector and measure the frequency of the pressure-vacuum in the chamber between the inlet and outlet nozzles of the ejector, in which the frequency of the natural oscillations of the oscillatory link is monitored.
