Abstract:
A vacuum measuring cell with a membrane between two planar housing parts has a first housing part forming a reference vacuum volume and the second housing part forming a measuring vacuum volume with a connection for the medium to be measured and a mechanism for measuring the membrane deflection. The membrane surface exposed to the medium to be measured is a structured surface.
