SIPART PS2-Flameproof

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
