StoneL’s new Prism PI integrates an advanced position sensing system and integral pneumatic control for sanitary diaphragm valves and other linear applications. The Prism PI is compact, durable, and well suited for corrosive, heavy washdown and hazardous areas.
StoneL created the PI as the next generation of the Prism series with a reduced envelope size to consume less space. The unique mounting system for the Prism PI allows fast, easy attachment to most popular diaphragm valves. The position of the pneumatic and conduit connections is optimised because the unit can be adjusted in 45° increments on the mounting pad of the valve.
The PI features an intelligent linear magnetic resistive sensor system to precisely measure stroke position at all times. Setup is performed in seconds with high-precision yet flexible switching, which is automatically (intelligently) calibrated depending on stroke length. Convenient, simple push button settings accurately lock in open and closed position, which remain in place when power is removed and reapplied.
The Prism PI is available in three versions: low profile, standard stroke and long stroke, depending on specific requirements. Precision feedback for stroke lengths varying from 4 mm up to 66 mm is available.
