耐震压力表结构原理 Working Principium
该仪表在Y系列一般压力表结构原理的基础上，依靠内部充填阻尼液体（硅油或甘油），装置 阻尼管，阻尼片及阻尼螺钉等措施，克服介质强烈脉动和环境振动给压力表带来的冲击损害，从而确保测量精度，延长仪表的使用寿命。
Besides the features of series y,series YN offer a significant cushioning and dampening effect,reduce the internal gauge damage and retain high accuracy of measure as well as provide a longer gauge life by filling damped oil and installing damped tube,piece and bolt.
