Abstract: An ionization vacuum measuring cell has: a) an evacuatable housing (10) with a measuring connection (8) for the vacuum to be measured, b) a first outer and a second inner electrode (3, 4) which are coaxially arranged in an interspaced manner with a common axis (7), whereby a measuring chamber (20) is formed between the two electrodes, the measuring chamber communicating with the measuring connection (8), c) a voltage source (16) which is connected to the electrodes (3, 4), d) a current measuring mechanism (17) for analyzing a discharge current generated between the electrodes (3, 4), and e) at least one permanent magnet ring (1) which surrounds the coaxial electrode (3, 4) arrangement, has a magnetizing direction (13) directed radially to the axis, and has a soft-magnetic yoke (2) that surrounds the permanent magnet ring (1).
