Esdun Industrial 
The 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.
Prepared for extreme applications: The SIPART PS2 valve positioner with a separate remote position detection can be used for valves at difficult accessible locations or for particularly critical process conditions, such as extreme vibrations or temperatures, dust or water influences. The following external position detection systems can be distinguished:
