WANG Gui-na, SU Xiao-guang. Research on performance test system of gas proportional valve[J]. 2008, (2): 30-31+34. DOI: 10.13873/j.1000-97872008.02.034.
A test system of gas proportional valve based on industrial personal computer(IPC) is developed.This test system is used for manufactories and quality supervisory departments to do the test of gas proportional valve performance more quickly and conveniently.This IPC’s system uses PCL—818L data acquisition card
24PCDFA6D pressure sensors and AWM720P1 thermal mass flow sensor to test the performances of gas proportional valve
and the curves of the performances are described.The performances include steady pressure performance p2 —p1 and controlling performance p2 —I or Q—I and so on.
