  1. This paper deriving the theory work inflection point in the static stage characteristics curve of small measurement range linear dimension measurement. by the way of high pressure and back pressure pneumatic measure and designed the parameter of the mainly and measure spray head, which are the key component in the spray head - baffle pneumatic sensor. the different groups for the main - spray head and the measure spray head, will effect the dynamic and static stage characteristic parameter. the author have done contrast experiment and optimization design to test and verify the theory derivation whereby made the rang of show valve of pneumatic measure system measure range up to 40 u m, the sensitivity up to 100mv / u m, resolution up to 0. 05 p m, the uncertainly of measure is less than 0. o2 u m, satisfaction of requirement of groups the carboy hatch thickness size precise measure of soft shims
