Method for performing pressure fluctuation calibration on differential pressure transducer

The invention discloses a method for performing pressure fluctuation calibration on a differential pressure transducer. A pressure fluctuation calibration device comprises a main pressure container, a standard pressure transducer, a rack and a cylinder body, wherein the standard pressure transducer is connected to the main pressure container, and the cylinder body is fixedly arranged on the rack. The bottom of an inner cavity of the cylinder body is communicated with the main pressure container through a second pipeline. The upper portion of the cylinder body is provided with a piston, and a guiding flange is fixedly arranged on the outer wall of the top of a piston rod. A stand column of the rack is used as a guide rail of the guiding flange, a displacement transducer is arranged on the guiding flange, and a transmission mechanism driving the piston rod to vertically move is arranged on the top of the rack. According to the pressure fluctuation calibration device and the calibration method, the fluctuation calibration requirements of the pressure of the usual on-spot environment or the pressure of the differential pressure transducer are met.
