Emerson recently 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. The PD Series enhances the current TopWorx portfolio of discrete valve controllers, providing 100% control over valve position and integrating communication via a 4-20 mA loop signal and HART protocols. Customers can extract valuable feedback through this intelligent communication and can monitor for trends that offer predictive maintenance insights to help prevent costly downtime. To maximize reliability, the PD Series uses Hall effect contactless position detection. Two PNP alarms that can be configured throughout the full displacement range help improve plant productivity and safety in any process application. The construction of the PD series product line is also designed to withstand a variety of environmental conditions. The PD Series will launch initially with two models: The PD100 for general purpose and non-incendive applications and the PD200 which is also intrinsically safe. The PD Series is suitable for use in oil and gas, chemical, industrial energy, on-site utilities, power generation, pulp and paper, waste and wastewater and food and beverage applications.
