艾默生, a global leader in fluid control andnpneumatics technology, has released the TopWorx™ PD Series Smart Valve Positioner. The PD Series expands on Emerson’s current portfolio of TopWorx sensing and control products, providing intelligence, reliability, and versatility to valve control.
PD系列增强了离散阀控制器的当前TopWorx投资组合，从而通过4-20 MA环路信号和HART协议提供了100％控制阀位置的控制权，并整合了通信。客户可以通过这种智能沟通来提取有价值的反馈，并可以监视提供预测维护见解的趋势，以帮助防止昂贵的停机时间。
为了最大化可靠性，PD系列使用Hall效应无接触位置检测。可以在整个整个位移范围内配置的两个PNP警报有助于在任何过程应用中提高植物生产力和安全性。PD系列产品线的构建还旨在承受各种环境条件。PD系列最初将使用两种型号启动：用于通用应用的PD100和用于爆炸气氛的PD200。
“Every facility, no matter its environment, needs to be sure it’s operating as safely and efficiently as possible,” said Paul Bristow, Global Product Manager at Emerson. “That’s why the PD Series was designed for trusted performance in demanding conditions in many different applications and industries.”
The compact and lightweight design of the PD Series delivers a high degree of versatility, allowing for quick and simple installation on rotary and linear actuators in many applications. The same solution can provide precision control on both single- and double-acting actuators. An LCD screen allows operators access to device status and optional magnetic key technology allows operators to set all functions of the device without removing the cover in the field. Low air consumption and fast response deliver efficient operations, providing a single solution for both standard and heavy-duty conditions.
Topworx PD系列与其他经过验证的Topworx产品相同的行业领先标准构建，可为苛刻的应用提供出色的价值和可信赖的性能。PD系列适用于石油和天然气，化学，工业能源，现场公用事业，发电，纸浆和纸张，废物和废水以及食品和饮料应用。
