ABSTRACT:
A pressure sensor comprises an optical system which is coupled to a diaphragm an which couples light emitted by a transmitting light guide into two receiving light guides depending on the deflection of the diaphragm. In order to enable the pressure values thus detected to be measured by means of a simple circuit, the transmitting light guide and the receiving light guides are arranged parallel to the diaphragm and the optical system is constructed as a focusing system, preferably a spherical lens arranged to be movable by the diaphragm 11 in a direction perpendicular to this diaphragm.
