A Comparison of Deadweight Testers and Digital Pressure Calibrators – Part 2

Deadweight Testers and Digital Pressure Calibrators Primary vs. Secondary Standards Deadweight testers are primary standards.  This is because they are based solely upon physical parameters and the pressure measurement is not translated into an electronic or analog signal.  Since they are a physical standard, they can be made to cover wide pressure ranges using different masses and effective area components.  Conversely, these units are bulkier and much heavier than most digital standards.  They are often more difficult to set up and require more training to become an efficient user than would be the…Read more
