ABSTRACT:
A force and mass meter using two transversally vibrating preloaded strings as the force sensitive members. The two strings are placed in a transverse magnetic field and are caused to vibrate by means of an exciting current flowing across them which is delivered by one exciter each. The exciters consist of a metering bridge, and an operational amplifier deriving the exciting current from the error signal measured across the bridge. Mutual interference of the two exciters is drastically reduced, when the point of common potential of the two exciters is connected with at least one conductor to each of the exciters.
