Manufacturing product monitoring for properties w.r.t. pressure medium - subjecting it to medium and measuring pressure parameters taking account of leakage near test device

摘要

A manufacturing product is monitored w.r.t. its properties relative to a press. medium by subjecting it to a press. medium measuring the press. parameters and deriving the monitored characteristics. The variations in the press. parameters caused by leakage in the region of the test device are detected and taken account of. This involves the monitoring of a master product corresp. to the monitored product as far as the characteristic of interest is concerned. USE/ADVANTAGE - For monitoring capacity and/or leakage testing of hollow vols. in manufacturing products. Improved accuracy.
