Abstract

In many industrial applications a connecting tube between the measured object and the pressure meter is a component part of the pressure measurement system, which may significantly influence the accuracy of the dynamic measurements of pressure. The aim of the paper is to determine the optimal dimensions of the connecting tube from the viewpoint of magnitudes of amplitude dynamic errors. The limit frequencies of the pneumatic pressure measurement system with connecting tubes of different dimensions were obtained with Bergh and Tijdeman mathematical model and experiments.
