Abstract

In some specific applications, the strain-gauge bridge branches are separated and remote. Lead resistances between bridge branches and the measuring instrument introduce significant measurement error. The well-known error compensating circuits do not suit all applications, or they cannot be added to the already existing instrumentation without modification of its internal circuits. A circuit for lead resistance compensation and complex balancing of the 1/4 and 1/2, AC or DC excited bridges is described. It is possible to add this circuit in front of the instrumentation already in use with no modification of the instrumentation itself
