Title:
LINEAR VARIABLE DIFFERENTIAL TRANSFORMER WITH DIGITAL ELECTRONICS
Document Type and Number:
WIPO Patent Application WO2003100355
Kind Code:
A3
Abstract:
Techniques for coupling with devices that convert displacements into differential voltages and improve the sensitivity of such devices. The disclosed system improves the accuracy and resolution of a transducers such as an LVDT by converting certain parts of the circuit to a digital circuit. One embodiment uses a processor 80, although other digital processing circuitry may also be used.
