ABSTRACT:
A dip angle data transmitter wherein a laminated pendulum, housed in a viscous fluid completely filling a casing, is arranged in the latter so that the distance between the surfaces of the pendulum's plates and the inner surface of the casing is found from the following formula: ##EQU1## WHEREIN .chi. IS THE DISTANCE BETWEEN THE SURFACES OF THE PENDULUM PLATES AND THE INNER SURFACE OF THE CASING FOR THE GIVEN TWO POINTS;
.nu. is the kinematic viscosity of the viscous fluid at a minimum working temperature;
.omega. is the natural frequency of the transmitter oscillations; and g is the gravity acceleration.
