摘　　要：石油化工工业流程中,由于强烈的机械振动和介质压力剧烈脉动的影响,导致震动工位压力仪表频繁故障,且指针抖动幅度较大,影响了计量的准确性。为了解决上述问题,研制了压力仪表减震缓冲装置,通过延长脉冲路径,规避共振原理,进而实现降低减震幅度,减少仪表故障率,提高计量准确性的目的。The strong mechanical vibration and frequent fluctuation of medium pressure caused the frequent malfunction in vibration station pressure instrument as well as pointer jittering, which affect the measurement accuracy. The pressure gauge shock absorber is developed to resolve the above problems by extending the pulse path and avoiding resonance principle to reduce the damping amplitude and the instrument failure rate as well as to improve the accuracy of measurement.
