Means for determining the pressure in a tube or pipe without coming into contact with the measured substance, especially for small nominal distances

摘要

The device (1) has a tubular housing (2) containing a membrane (8) the end of which is connected in a gas-tight manner with the housing. A pressure chamber (9) is formed at least partly between the membrane and the inner wall of the housing and this receives the pressure medium. The membrane has, at least looked at in cross-section in the middle section, a circular circumference which is interrupted by at least one segment section.
