Over 2 Million SIPART PS2 Positioners Sold!
Siemens SIPART PS2 is the most widely used valve positioner for linear and part-turn actuators in industrial applications. The all-round positioner of Siemens provides an extensive range of functions and is well equipped – even for extreme ambient conditions. The following enclosure options are available: Polycarbonate, Aluminum, Stainless steel, Flameproof aluminum or 316L stainless steel.
The SIPART PS2 positioner is used, for example, in the following industries:
- Chemical/petrochemical
- Power stations
- Paper and glass
- Water, waste water
- Food and pharmaceuticals
- Offshore plants
The SIPART PS2 positioner is available:
- For single-acting actuators: In Makrolon, stainless steel or aluminum enclosure, as well as flameproof aluminum enclosure
- For double-acting actuators: In Makrolon enclosure, stainless steel enclosure and flameproof aluminum enclosure
- For non-hazardous applications
- For hazardous applications in the versions
- Intrinsic safety type of protection
- Flameproof enclosure type of protection
- Non-sparking type of protection
- Dust protection by enclosure type of protection
and in the versions:
- With 0/4 … 20 mA control with/without communication through HART signal
- With PROFIBUS PA communication interface
- With Foundation Fieldbus (FF) communications interface.
Explosion-proof versions
- Device with protection type “intrinsic safety” for use in Zone 1, 2, 21 / Class I, Division 1, Groups ABCD
- Device with protection type “dust protection with enclosure” for use in Zone 22
- Device with protection type “non-sparking” for use in Zone 2 / Class I, Division 2, Groups ABCD
- Device with protection type “flameproof enclosure” for use in Zone 1 / Class I, Division 1, Groups ABCD
Stainless steel enclosure for extreme ambient conditions
The SIPART PS2 is available in a stainless steel enclosure (with no window in the cover) for use in particularly aggressive environments (e.g. offshore operation, chlorine plants etc.). The device functions are the same as for the basic version.
Benefits
SIPART PS2 positioners offer decisive advantages:
- Simple installation and automatic commissioning (self-adjustment of zero and span)
- Simple operation with
- Local operation (manual operation) and configuration of the device using three buttons and a user-friendly two-line display
- Parameterization via SIMATIC PDM
- Very high-quality control thanks to an online adaptation procedure
- Negligible air consumption in stationary operation
- “Tight shut-off” function (ensures maximum positioning pressure on the valve seat)
- Numerous functions can be activated by simple configuring (e. g. characteristic curves and limits)
- Extensive diagnostic functions for valve and actuator
- Only one device version for linear and part-turn actuators
- Few moving parts, hence insensitive to vibrations
- External non-contacting position sensor as option for extreme ambient conditions
- “Intelligent solenoid valve”: Partial Stroke Test and solenoid valve function in a single device
- Partial Stroke Test e. g. for safety valves
- Can also be operated with purified natural gas, carbon dioxide, nitrogen or noble gases
- SIL (Safety Integrity Level) 2
