ABSTRACT:
A pressure transducer of miniature design with a silicon diaphragm which is provided with a monolithic resistor arrangement, the resistance of which changes with the deformation of the diaphragm in which the diaphragm is arranged between two overload bodies, one of which rests on a support body, whose surfaces facing the diaphragm are each provided with a pressure chamber and pressure canals to obtain an overload-proof pressure transducer which is very small and can be used for measuring large pressure differences.
