Method and instrument for determining the moisture content and/or temperature of moving material
Abstract
Abstract A METHOD AND APARATUS FOR MEASURING THE MOISTURE CONTENT OF A MOVING MATERIAL BY USING A MOSITURE SENSING DEVICE WHICH SUPPLIES AN ELECTRICAL OUTPUT SIGNAL AS A FUNCTION OF THE VALUE OF THE MOISTURE BEING DETERMINED. A COVER OF NON-HYDROSCOPIC, THERMALLY INSULATING MATERIAL IS FIXEDLY DISPOSED SO AS TO BE SLIGHTLY SPACED FROM THE SURFACE OF THE MOVING MATERIAL. THE COVER IS PROVIDED WITH MEANS FOR CAUSING THE ATMOSPHERE PASSING BETWEEN THE COVER AND THE SURFACE OF THE MATERIAL TO BE DRAWN OFF AND MOVED PAST, AND INTO CONTACT WITH, THE MOISTURE SENSING DEVICE. THE ATMOSPHERE, BEFORE BEING MOVED PAST THE MOISTURE SENSING DEVICE, IS FIRST BROUGHT INTO CONTACT WITH A TEMPERATURE VARYING DEVICE FOR PERMITTING THE TEMPERATURE OF THE ATMOSPHERE TO BE SELECTIVELY VARIED.
