YN系列耐震压力表 系引进国际先进生产技术制造，该产品适用于测量无爆炸危险、不易结晶、不凝固及对零件不起腐蚀作用的液体、气体和蒸汽等介质的压力和负压，特别适用于强烈脉动介质压YN系列耐震压力表系引进国际先进生产技术制造，该产品适用于测量无爆炸危险、不易结晶、不凝固及对零件不起腐蚀作用的液体、气体和蒸汽等介质的压力和负压，特别适用于强烈脉动介质压力和环境强烈振动场所介质压力的测量，能在强振动环境中将示值稳定地指示出来。
YN series filled pressure gauge is based upon the advanced process technology of world.It is suitable for measuring the pressure or vacuum of liquid,gaseous and vaporous media that will not explode,crystallize or corrode the elements.Especially,it offer a significant cushioing and dampening effect,so can steadily indicate the pressure of media in a sharp pulsation condition.
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.
使用与订货须知 Notice for Using and Order
使用中若环境温度高，仪表指示不能回零，可用细针在仪表橡皮塞上通一小孔，使仪表内腔与大气相通即可。
使用环境温度：-25℃～70℃
使用工作频率不大于25Hz,振幅不大于1mm。
订货时请注明名称、型号、测量范围及工作温度。如有特殊要求，请明确参数，本厂可设计定制特种耐震压力表。
If the ambient temperature is so high that the gauge pointer does not return zero,in order to resolve it you may stick a small hole on the gauge seal with a needle,and the gauge inner will connect with the atmosphere.
Working condition temperature:-25℃～70℃
Working frequency is not to up 25Hz and amplitude of oscillation is not to up 1mm.
Please note name,model and measuring high limit on your order,and special filled pressure gauge can be provide on request.
