ABSTRACT:
A pressure sensor Comprising a disk-type base part having a preferably central opening spanned at one end by a surface-type pressure transducer, a pressure receiving part having a diaphragm arranged at distance from the other end side of said opening and integrally formed with a rigid ring having the same peripheral dimensions as the disk-type base part and being connected thereto. A distance holder is provided between the diaphragm and the pressure transducer fully transmitting any deformation of the diaphragm to the pressure transducer. Such a pressure transducer may be manufactured by a simple and cost-effective procedure with the various elements formed of ceramic, sintered and combined.
