Emerson TopWorx PD Series designed to operate in a range of environmental conditions.

Emerson has released the TopWorx PD Series Smart Valve Positioner that integrates communication via a 4-20mA loop signal and HART protocols. The PD Series uses Hall effect contactless position detection. Two PNP alarms can be configured throughout the full displacement range. The PD Series will launch initially with two models: The PD100 for general purpose applications and the PD200 for use in explosive atmospheres. The series can provide precision control on both single- and double-acting actuators. An LCD screen provides access to device status and optional magnetic key technology. The 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.
