Membrane type pressure sensor has a circular membrane that is divided into concentric areas of varying cross section, so that pressure can be measured accurately over a wide range

摘要

Pressure sensor has a base body (1) and a circular disk shaped membrane (3) that is connected to the base body around its outer edge (5). One or more concentric circular webs (7, 9) are arranged between the outer edge of the disk and its center so that the membrane rests on, or is connected to them. Electromagnetic transducers convert the deformation of the individual membrane areas (I, II, III) by the applied pressure into electrical signals.
