Pneumatic amplifier is not only the commonly used independent electrical attachment but also one of key components of the valve positioner. In this paper, a mass flow mechanism model of the typical pneumatic amplifier is established, and the method of parameter identification is proposed. Firstly, according to the working principle and structural characteristics of the pneumatic amplifier, the mass flow model of the pneumatic amplifier is established by using the principle of thermodynamics anddoi:10.2991/msota-16.2016.43 fatcat:lhhnldt7snebzh5lcmuaihyckm
