| 摘 要： | 智能阀门定位器目前已能成功应用，但仍处于一个发展阶段。由于其各种性能指标的意义及表述还不十分清楚，各公司、各产品的功能差别很大，价格差异也较大，使得设计选型产生较多困难。这也是目前智能阀门定位器的应用不像智能变送器那样广泛应用的原因之一，现探讨智能阀门定位器在设计选型过程中出现的一些新问题。

| Abstract: | Smart valve positioners have been applied successfully, but they are still in the developing stage. Because the meaning and manners of formulation for various performance datum are not vary clear, Different manufacturers and their different products are much different in function and price. It is one of the reasons why the application of smart valve positioner can not be as wide as smart transmitters. It is discussed that the new problems are appear in design and selection of smart valve positioner. |
