Toroidal Electrolytic Angle Transducer
US Patent:
3946494, Mar 30, 1976
Filed:
Sep 30, 1974
Appl. No.:
5/510662
Inventors:
Perry L. Wells - Loveland CO
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
G01C 906
US Classification:
33366
Abstract:
A toroidal electrolyte-type angular transducer is provided for measuring angular displacement or tilt from a vertical plane. Three conducting paths in the electrolyte are established between two measuring electrodes and an auxilliary electrode respectively and a common electrode. Angular displacement is simply related to the values of the conductances in the various paths. In a preferred embodiment of the invention several guard-ring electrodes are included to divert spurious leakage currents from the common electrode so that the leakage current will not affect the measurement. The guard-ring electrodes are maintained at the same potential appearing at the collector electrode to ensure that no leakage currents pass between the two. Another preferred embodiment the invention provides that the two measuring electrodes are driven by voltages equal in magnitude and opposite in sign. A high gain operational amplifier is interconnected between the auxiliary electrode and the common electrode.
