Siemens Series PS2 Electropneumatic Positioners
The SIPART PS2 electropneumatic positioner is used to control the final control element of pneumatic linear or part-turn actuators. The electropneumatic positioner moves the actuator to a valve position corresponding to the setpoint. Additional function inputs can be used to block the valve or to set a safety position.
The PS2 is the state-of-the-art in valve positioners. Compatibility with HART, Fieldbus and Profibus is available. Partial stroke testing and advanced diagnostics are standard.
The PS2 is also a no-bleed device when in steady-state, and the PS2 can be operated with natural gas. No hand-held devices or calibrators are required. Any configuration and setup can be done through the integral interface. Rated SIL (Safety Integrity Level) 2.
