Siemens SIPART PS2 Electropneumatic Valve Positioners

SIPART PS2 is currently the most widely used positioner for linear and part-turn actuators in a wide range of process industries. This is not without reason. The proven all-round design has a particularly flexible stroke range, intelligent diagnostics, and communicates either via HART, PROFIBUS PA or Foundation Fieldbus. What has been proven so often is certainly the correct choice.
Designed in a Macrolon, aluminum or stainless steel casing, the SIPART PS2 positioners are suitable for all applications. Designed as standard with IP66 or NEMA 4x degree of protection, they are resistant to even the most hostile environments. SIPART PS2 is also available with an explosion-proof enclosure with EExd IIC T4-T6 type of protection.
SIPART PS2 exhibits its communicative side in dialog with higher-level systems. It can be integrated into the communications landscape via PROFIBUS PA, Foundation Fieldbus or HART protocol. With HART and PROFIBUS, it is also possible to apply SIMATIC PDM to clearly display and document saved trends, histograms, as well as commissioning and operating data.
If you would like to test your solenoid valve or replace its function by a positioner, SIPART PS2 prevents valves from closing or monitors open/close valves as an "intelligent solenoid valve.
By means of a regular partial stroke test, SIPART PS2 ensures that ESD valves (emergency shutdown) and other open/close automated valves remain movable in the event of an emergency. The attached solenoid valve can also be tested.
SIPART PS2 is equipped with comprehensive diagnostics functions as standard. In order to provide advanced warning of expensive failures during operation, our positioners continuously check the actuator and valve.

The most widely used intelligent positioner for linear and rotary actuators, Siemens SIPART® PS2 electropneumatic positioner is used to control their final control elements. The PS2 electropneumatic valve positioner excels through its reduced installation overheads, function expansion with low-cost option modules, and enhanced diagnostics. With its wide range, and an infinitely adjustable 3- to 130-mm stroke range, SIPART PS2 can be directly integrated to modern actuators without pipe work and without additional overhead. And it can be used with even the smallest actuators because the fully integrated valve block comprehends external position signals, and makes SIPART PS2 a lot more compact.
