美国霍克HOKE仪表管全进口阀件：
仪表的重要性：相反仪表投入运行不到3个月，仪表零位就变了，介绍仪表稳定性不好。仪表稳定性的好坏直接关系到仪表的消耗范围，有时直接影响化工生产，仪表稳定性不好造成的影响往往双仪表精度回落对化工生产的影响还要大。仪表稳定性不好仪表维护量也大，是仪表工最不期望出现的事情。
概述：仪表管阀件是指输气管道上的连接仪表或阀门的一些零件、接头和阀门等。
特点：随着仪表更新换代，特别是微电子技术引入仪表制造行业，使仪表可告性大大提高。仪表生产厂商对这个性能指标也越来越重视，通常用平均无故障时刻MTBF来描述仪表的可靠性。一台全智能变送器的MTBF比一般非智能仪表如电动Ⅲ变送器要高10倍左右，它可高达100~390年。
With the renewal of instruments, especially the introduction of microelectronics technology into the instrument manufacturing industry, the instrument can greatly improve the efficiency of the instrument. Instrument manufacturers also pay more and more attention to the performance indicators, usually with an average failure time MTBF to describe the reliability of the instrument. A fully intelligent transmitter MTBF than the general non intelligent instruments such as electric III transmitter to be about 10 times higher, it can be up to 100~390 years.
