ABSTRACT:
A multi-line electronic media barrier or safety system for preventing liquid contamination of air lines, including a capacitance proximity sensor for detecting a foreign undesirable medium such as paint in an air line. When foreign media is detected, a main air valve is closed which in turn closes valves connected in the air lines, thereby blocking passage of air or liquid and protecting pneumatic control apparatus. The media barrier is especially designed for use with automated or robotic paint spray devices utilized in industry.
