Description of SIPART PS2 Positioner
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.
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.
Benefits of SIPART PS2 Positioner
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 closing" 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 sensor as option for extreme ambient conditions
- "Intelligent solenoid valve": Partial Stroke Test and solenoid valve function in
one 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
Application of SIPART PS2 Positioner
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.
