Abstract

A measuring circuit used for the capacitive examination of a moving elongated textile test material such as card sliver, roving, yarn or woven fabric, having a measuring capacitor for accommodating the test material, and a component with a capacitance which can be changed by an electric control signal. The measuring circuit can thus be balanced in a simple, rapid, cost-effective and especially automatic way.
