摘要：
A dispensing system for feeding paste through a screen onto a workpiece monitors the position of a piston applying pressure to the paste with a linear variable differential transformer and sets limits on the slope of the piston displacement is a measure of the feed rate and the “spring back” of the piston when pressure is re- leased, as a measure of trapped air in the system.
