Abstract
A load platform with multiple stress sensitive magnetic member supports is disclosed in which the frequency of an electrical output signal is proportional to the applied platform load. This device consists of multiple magnetic stress sensitive members in which mechanical stress is induced by the platform load and a magnetic multivibrator constructed so the stress sensitive magnetic characteristics of the stress members are the principal frequency determining elements of the magnetic multivibrator. Also disclosed are various stress member loading configurations, a laminated stress member, and methods for zero-load, linearity, and scale factor adjustments in the variable frequency transducers. Also disclosed is an adjustable frequency-sensitive switch which can be used as a load switch.
