APPARATUS FOR DETERMINING CONTENTS - FIRST OF ALL HUMIDITY - OF MATERIALS WITH HIGH FREQUENCY METHOD

摘要

The sensor system (3) is fitted in the container (1) for holding the substance (2) to be measured. The pulse-processing high-frequency instrument (4), which mechanically forms a unit with the sensor system (3), is arranged above the sensor system (3). These are surrounded, up to the filling level (h), by the substance to be measured (2) flowing into the container (1). The output signals of the pulse-processing high-frequency instrument (4), which depend on the moisture content of the substance, pass to the analysis instrument (5). The direct assembly of the pulse-processing high-frequency instrument (4) together with the sensor system (3), as well as linearising and zero point-stabilising circuitry ensure reliable operation and high measurement accuracy even in an industrial environment.
