The SIPART PS2 positioner from Siemens sets the standard for precise, reliable, and efficient valve control. Designed for ease of use and maximum performance across industries, it combines advanced functionality with robust design.
Key Advantages & Features:
Quick & Easy Setup: Simple installation with automatic initialization (self-adjustment of zero and span).
Удобное управление: Local control and configuration via three buttons and a clear two-line display. Also configurable via SIMATIC PDM software.
Superior Control Quality: Achieves high-precision control thanks to its online adaptive program.
Energy Efficient: Negligible air consumption during steady-state operation.
Reliable Safety & Control Functions:
Tight Shut-Off: Ensures maximum seating pressure.
Fail-in-Position (Pressure Retention): Maintains last position on power or signal failure (not for use in SIL applications). Example: Position stability of 0.3%/h for an 8L actuator.
High Flexibility: Easy configuration enables multiple functions like characteristic curves and limit setting.
Расширенная диагностика: Extensive diagnostic capabilities for valves and actuators.
Universal Fit: One model fits both linear and part-turn actuators.
Robust Design: Minimal moving parts for low vibration sensitivity.
Versatile Applications: Can be used with non-hazardous process gases like natural gas, CO₂, nitrogen, or inert gases as supply air.
Integrated Partial Stroke Testing (PST): The “Smart Solenoid Valve” function combines solenoid valve functionality with partial stroke testing, ideal for safety valve applications.
Comprehensive Valve Testing: Supports full stroke tests, multi-step response tests, and valve performance tests for maintenance evaluation.
Functional Safety: Compliant with Safety Integrity Level (SIL) 2.
Harsh Environment Ready: Option for external non-contact position sensor for extreme conditions.
