Digital valve positioner extends features
Spring House, Pa. - SIPART PS2 is Siemens newest digital valve positioner incorporating auto-tuning, improved diagnostics, and actuator leak test as standard in all units, permitting users to identify and schedule necessary maintenance actions, thereby avoiding unplanned shutdowns. The PS2 supports Profibus-PA or HART communications protocols and can be operated through a Microsoft Windows-based HMI using simple PC software. Where manual valve position actuation is preferred, PS2 is reported to support a simple built-in interface. Other features include user-defined ramping, tight shut-off, and full open settings; seven pre-set flow characterization curves; a 21-point user defined characterization curve; split-ranging; and a universal shaft for linear or rotary applications.
