Function

BALANCE-TYPE GRAVITY METER USED TO MEASURE CHANGES IN EARTH'S GRAVITATIONAL FIELD IN ORDER TO IDENTIFY AREAS OF HIGH DENSITY MASS SUCH AS ACCOMPANY ORE BODIES. IT WAS DESIGNED FOR OCEAN SURVEYS, FOR MAKING MEASUREMENTS AT SEA FROM MOVING SHIP. DEVICE CONSISTS OF MASS AT END OF HORIZONTAL ARM THAT IS SUPPORTED TORSION-SPRING ROTATIONAL AXIS.

Technical

2ND GENERATION GRAVIMETER SYSTEM DESIGNED FOR USE AT SEA (1ST GENERATION WAS BUILT IN 1950S). UNIT WAS MODIFIED AT BIO TO PERMIT GREATER ROLL OF SHIP CONTAINING IT (FROM 15 TO 25 DEGREES). GRAVIMETERS FOR USE ON LAND & IN AIRCRAFT WORK ON THE SAME PRINCIPLES THOUGH AT SEA STABILITY IS MUCH GREATER PROBLEM.
