Gravimeters with quartz elastic systems that use torsion balances employ a third quartz wire or spring, making possible certain advantages including the use of a capacitance displacement-transducer. The accuracy characteristics of this type of system are evaluated with consideration given to (1) errors caused by wire geometry, (2) errors caused by wire stiffness, (3) temperature compensation, and (4) zero-point drift.
