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.
