Advantages of SIPART PS2 positioners
- 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 an 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
