A MICRO CAPACITIVE TRANSDUCER, OF GREAT SENSITIVITY FOR GEOPHYSICAL APPLICATIONS
(Abstract)

The paper presents a capacitive transducer meant for modernizing the underground earth tides studying devices. The block diagram, the equivalent representation, as well as the drawings commented in the text – analytically written in the appendix – show the design features.
The transducer built in a compact form, using only Romanian made elements, has a small size, great sensitivity, good time stability, high kable linearity. These characteristics allow its use for other scientific research fields, as well as for automation purposes.
