Abstract
A method of, and apparatus for, measuring the moisture content of flat textile structures, especially textile webs, wherein there are produced, by virtue of the measuring operation, useful signal components of the same polarity dependent upon the conductance of the test material. There are produced disturbance signal components of opposite polarity dependent upon external voltages. And the useful signal components are additively processed into a measurement value, whereas the disturbance signal components, by addition thereof, due to their opposite polarity, at least approximately eliminate one another.
