Position Detection for Pneumatic Cylinders.

摘要

The two most widely used techniques for position detection on pneumatic logic controlled production equipment are the use of limit valves and of sequencing. These techniques are also suitable for use with fluidic logic. This report describes a new technique of position detection by determining the location of cushioning in a pneumatic cylinder, as recently developed by the Ammunition Engineering Directorate, Picatinny Arsenal. It also includes a comparison of that technique with the widely used one employing limit valves and sequencing.
