ABSTRACT:
In a mechanical electrical transducer strain-sensitive resistors (26, 27) are arranged on a strain member (7, 28, 38, 51, 53) in each case on sections (16-18; 32, 33; 45-48; 58-60) developed in transverse-beam fashion, which from the center of the strain member, are arranged tangentially to a circular arc extending concentrically to the center of the strain member. The transverse-beam sections are subjected on their surfaces substantially only to one-dimensional states of stress. The pairs of strain sensitive resistors are therefore stressed in a manner which does not simulate changes in pressure.
