Geodetic System

To level the X- and Y-axes of the Model 520-W Geodetic Platform Tiltmeter, the user turns a knob that raises or lowers an invar screw by means of a worm gear assembly. One complete 360° turn of the knob turns the screw by 6°, or 1/60 of a revolution. The ½-inch diameter screw has a pitch of 40...

The Carnegie Institution of Washington has installed two Jewell Instruments Model 510 Geodetic Borehole Tiltmeters in the sea floor east of Japan. The scientists are attempting to establish long-term sea floor observatories in one of the world's most active earthquake zones. Each observatory...
