A software plug-in that enables certain diagnostic tests to be run on its products is now available. ValveAnalysis works with Emerson Process Management’s AMS Suite to run the Ramp Signature test for the identification of leaks in tubing fittings, improperly aligned plugs and seats, loose linkage, broken actuator spring sand sticky spool valves. For the HDL test, the plug-in calculates the four standard diagnostic signatures — hysteresis, deadband, repeatability and linearity — by opening and closing valves. ValveAnalysis does not bypass AMS, thereby ensuring that a complete device history is maintained.
